Introduction

Terms

This section explains terminology speciﬁc to the TXn.

■ Amp Editor

This is computer application software. This software allows you to monitor and control the TXn ampliﬁers from your com-

puter.

■ Scene

Settings such as power-on/standby or mute for each ampliﬁer are called a “scene.” By recalling a scene, the saved settings

can be immediately applied to the ampliﬁers. Each TXn unit has 50 scenes.

■ Signal Path

This is the audio signal processing functionality provided by the internal DSP. Components organized into modules accord-

ing to their functionality are placed in the signal path.

■ Component

These are modules in the signal path that organize audio signal processing according to their functionality.

■ Library

The settings of all Speaker Processor components can be saved together in a library. A library can be saved only from Amp

Editor, but can be recalled from the unit’s front panel as well.

■ Device ID

This is an ID for uniquely identifying a TXn unit within a network. In order to allow monitoring and control from Amp Edi-

tor, you must specify non-conﬂicting IDs within a workspace.

t [PROTECTION] indicator

When the protection system is active, this indicator will light red. The protection circuit will operate in the following situa-

tions.

• If the ampliﬁer overheats and the output limiter operates

The speaker output will be attenuated if the heat sink of the ampliﬁer section exceeds 80°C (80%), and will be muted if

the heat sink exceeds 90°C (90%). The [PROTECTION] indicator will light at 80°C (80%) or higher.

• If the power supply overheats and shuts-down

The fan will rotate at high speed if the power supply section exceeds 90°C, and the analog circuits will shut down if it

exceeds 100°C. The [PROTECTION] indicator will light only if shut-down occurs.

• The thermal meter in the METER screen and in Amp Editor indicates the heat sink temperature of the amp section.

The temperature of the power supply section is not shown.

• If the load falls below 0.5 ohms

If a short occurs and the load falls below 0.5 ohms, the speaker output will be muted, and muting will be cleared approx-

imately 1 second later.

• If DC output is detected

The speaker output will be muted, and the power supply section will shut down.

• If the power supply malfunctions

The speaker output will be muted.

• If ultra-high frequencies, overcurrent, excessive total current, or maximum current is detected

The speaker output will be compressed.

y [BRIDGE] indicator

This will light green if the ampliﬁer mode is set to Bridge.

u [PARALLEL] indicator

This will light orange if the ampliﬁer mode is set to Parallel.

i [MUTE] indicator

This indicator will light red if muting is turned on by the [MUTE] button or from Amp Editor. When the power is turned on,

the output signal will also be muted and the indicator will blink red until audio begins being output.

•Even if mute is off, this indicator will blink if Solo was turned on from Amp Editor, or when the output has been muted by

the protection circuit.

o [MUTE] button

By holding down the [MUTE] button for one second or longer, you can turn muting on/off for that channel. When muting

turns on, the [MUTE] indicator will light. By holding down the [MUTE] button when the Solo function is turned on from

Amp Editor, Solo will be defeated.

!0 [ALERT] indicator

This will light to indicate an alert related to the ampliﬁer’s audio signal. If an alert for a speciﬁc channel has occurred, the

indicator of the corresponding channel will light; for other alerts, the indicators of both channels will light. At this time, the

alert message will appear in the upper part of the display.

!1 [CLIP] indicator

When the signal of the speaker output’s power amp section exceeds the clipping level, this indicator will light and the output

signal will be compressed.

!2 [SIGNAL] indicator

This will light green when the level of the signal being output from the [SPEAKERS] jack exceeds 1 Vrms (equivalent to

0.2 W into an 8 ohms load, 0.4 W into a 4 ohms load or 0.8 W into a 2 ohms load).

NOTE

TX6n/5n/4n Reference Manual

Controls and Connectors

!3 Encoders A, B

When the display shows the attenuation meter, these encoders adjust the attenuation of channels A and B. If any other

screen is displayed, encoder A moves the cursor and encoder B modiﬁes the parameter value.

• Only encoder A can be operated if you’re adjusting the attenuation when the ampliﬁer mode is Bridge.

!4 Display

This shows the ampliﬁer’s settings or a level meter. Refer to “Screen Structure” (page 13) for details.

• If the power supply is in Standby mode or if the LCD Setup’s Backlight setting is Auto OFF, the backlight will go dark if no

panel operation has been performed for ten seconds. It will light again when a panel operation is performed.

!5 Function buttons

These buttons move to the screen indicated above each button in the display. If a channel name (e.g., CH A, CH B) is

shown, this means that a parameter for that channel is displayed; press the corresponding function button to switch the

channel that is shown. These buttons may also operate in different ways depending on the screen shown in the display.

!6 [HOME] button

This accesses the HOME screen (page 15) in the display.

By holding down this button for three seconds or longer, you can switch the power between Standby and On modes. When

the conﬁrmation message appears, press the [ENTER] button to switch the setting.

!7 [EXIT] button

By pressing this button when the display shows a screen other than the HOME screen, you can move to the screen of the

next highest level.

•To temporarily disable panel lock, simultaneously hold down the [HOME] button and [EXIT] button for three seconds or

longer.

• If you hold down this button for three seconds or longer in the HOME screen, the FAULT OUTPUT connector output will

be reset (NC and C will be connected).

!8 [ENTER] button

Use this to select a parameter or to ﬁnalize an edited parameter value. Depending on the screen shown in the display, this

button may also be used in other ways. If the parameter value is blinking, you must ﬁnalize the value by pressing this but-

ton.

• If you hold down this button for one second or longer in the HOME screen, the UTILITY screen Device Setup page (page

19) will appear.

!9 Air intakes

The ampliﬁer uses forced-air cooling. The variable speed cooling fan draws air in from the front and exhausts it through the

rear. The cooling fan speed varies depending on the heat sink temperature: It operates at low speed when it is below 40 °C

(40%), increases in speed according to increases in temperature, and operates at high speed when temperature exceeds 60

°C (60%). If the power supply exceeds 90°C, the variable speed fan will operate at high speed regardless of the heat sink

temperature.

Please be sure that you do not block the air intakes or exhaust vents. Also, clean the ﬁlter elements regularly. If the air

intakes are clogged with dust or debris, the ampliﬁer will overheat, which may result in the ampliﬁer shutting down.

@0 Screw holes for handles

These four screw holes (four locations) are for the included handles. Fix the handles to the ampliﬁer, using the included ﬂat-

head screws.

NOTE

TX6n/5n/4n Reference Manual

Controls and Connectors

@1 [SPEAKERS] jacks

These are speaker output jacks.

• Speakon connectors : Speakon type cable plugs (Neutrik NL4) can be connected here.

• Five-way binding post connectors : Bare wires or Y plugs can be connected here.

• The ﬁve-way binding post connectors and Speakon connectors are internally connected in parallel. If you’re using both

simultaneously, make sure that the speaker impedance of each connector is 4–16 ohms (8–32 ohms in Bridge mode).

@2 Digital input/output connectors (I/O card slot)

An AES-IO card is installed as standard, allowing AES/EBU digital audio signals to be input and output.

• [IN] connector : This is an XLR-3-31 type balanced input connector for inputting two-channel digital audio sig-

nals.

• [OUT] connector : This is an XLR-3-32 type balanced output connector for outputting two-channel audio signals

processed by the internal DSP.

• [THRU] connector : This is an XLR-3-32 type balanced output connector that outputs the unprocessed signal received

at the [IN] connector. Even if the power is turned off, this connector will output the input signal

without any change (page 44). However, internal settings will be switched when the power is

switched on/off, causing the output signal to be muted for an instant.

• If desired, you can remove the AES-IO card and install a separately sold MY card. For details on the types of MY card

that can be used and how to install them, refer to “Optional I/O cards” (page 9).

• The removed AES-IO card cannot be installed and used in other devices.

•You must use a 110 ohm digital cable to make AES/EBU connections.

@3 Analog input/output connectors

These connectors input and output analog audio signals.

• [IN] connector : These are XLR-3-31 type input connectors for inputting ana-

log audio signals. The pin polarity is shown at right (IEC

60268).

• In Parallel mode and Bridge mode, only the signal of

channel A is output from the speaker output connector

by default. The channel B signal is not sent from the

speaker output, but the audio signal processed by the

internal DSP can be output from the digital output con-

nector.

• [THRU] connector : This is an XLR-3-32 type balanced output connector

that outputs the unprocessed analog signal received from

the [IN] connector.

Controls and Connectors

@4 [NETWORK] connector

This is a 100BASE-TX/10BASE-T Ethernet connector. You can connect this to a computer so that the ampliﬁer can be mon-

itored and controlled from Amp Editor. This also allows an external controller such as AMX or Crestron to be connected.

•To prevent electromagnetic interference, use an STP (Shielded Twisted Pair) cable for the [NETWORK] connector.

@5 [FAULT OUTPUT] connectors

This is a 3P Euroblock connector for controlling an external analog device when an abnormality occurs in the CPU or trig-

gered by the occurrence of a Fault event speciﬁed in Amp Editor. NC and C will be connected when the ampliﬁer is operat-

ing normally; NO and C will be connected when a problem occurs (page 51). You can also reset this output from Amp

Editor.

A message will appear in the screen if a problem occurs. To reset the output, hold down the [EXIT] button for three seconds

or longer in the HOME screen.

@6 Power cable

Connect the plug of the power cable to an AC outlet of the correct voltage.

@7 Grounding screw

The AC power cord is a 3-wire type. If the AC outlet used is earthed (grounded), this device will be properly earthed as well.

Also, grounding the screw sometimes reduces hum and interference noise.

■ Supported I/O cards

You can remove the AES-IO card from the TXn’s rear panel, and install a separately sold MY (mini-YGDAI) card. As of Sep-

tember 2009, the following MY cards are supported. For the latest information, refer to the Yamaha pro audio website.

Backup : The input signal from the card installed in the slot will be the main signal; if the

input from the card becomes unlocked, the ampliﬁer will automatically switch

to the input from the analog jack. Refer to “Supported I/O cards” (page 9) to

check if your I/O card supports the Backup mode.

Override : The input signal from the card installed in the slot will be the main signal; if

input from the analog jack is detected, the ampliﬁer will automatically switch to

the input from the analog jack.

Auto Return ON/OFF When using Backup mode, this speciﬁes whether the slot input will be re-enabled when the

interrupted slot input has recovered.

When using Override mode, this speciﬁes whether the slot input will be re-enabled when the

analog input is interrupted.

Ovrrid Ch Link ON/OFF When using Override mode, this speciﬁes whether both channels will switch together (ON) or

separately (OFF) when analog input is detected as being present or absent.

Ovrrid Thrsld -30.0–0.0 dBFS When using Override mode, this speciﬁes the input level threshold value used to determine

the presence or absence of analog input.

■ Signal Chain

Here you can make settings for checking whether the input or output has been interrupted by a broken connection, etc.

● Analog Input Signal Chain/Slot Input Signal Chain

Here you can make settings to specify how a pilot tone supplied from the external device will be detected to determine whether

the input has been interrupted by a broken connection, etc. The settings for the Analog Input and the Slot Input are separate, but

the items to be set are identical.

● Output Signal Chain

Here you can specify how the speaker output impedance will be detected to determine whether the output has been interrupted

by a broken connection or a failed speaker. By outputting a pilot tone, the impedance can be detected reliably without relying

on the audio signal output.

• The impedance and output level cannot be detected when the output level is lowered by the attenuator.

Parameter name Range Explanation

Enable ON/OFF Enables/disables monitoring of input interruptions. If a pilot tone greater than the level spec-

iﬁed by Detection TH could not be detected within the time speciﬁed by Detection Time, it will

be determined that the input has been interrupted.

Detect TH -80.0–0.0 dBFS Speciﬁes the threshold value for the pilot tone input level.

Detect Time 0–100 s Speciﬁes the detection time for the pilot tone. If the pilot tone was not detected within the

speciﬁed time interval, it will be determined that the input has been interrupted.

Frequency 5 Hz–40.000 kHz Speciﬁes the center frequency of the pilot tone. If the sampling frequency is 44.1/48 kHz, a

pilot tone above 20 kHz cannot be detected appropriately.

Notch On ON/OFF Enables/disables the notch ﬁlter that eliminates the frequency component of the pilot tone so

that the pilot tone will not be output by the ampliﬁer.

Notch Q 0.10–63.0 Speciﬁes the width of the notch ﬁlter’s frequency band.

Detected Lvl — Indicates the level of the detected pilot tone.

Parameter name Range Explanation

Frequency Type 5 Hz & 20 kHz,

10 Hz & 20 kHz

Speciﬁes the center frequency (5 Hz or 10 Hz) for the low-frequency component of the pilot

tone that is output to the speaker. The high-frequency component is ﬁxed at 20 kHz.

With the exception of Detect Time, the parameters listed below are displayed and edited

separately for the high-frequency component (High) and low-frequency component (Low).

Tone Level -17.8–22.22 dBu Speciﬁes the output level of the pilot tone.

Enable ON/OFF Enables/disables monitoring of output interruptions.

Detect ImpMax 0.0–250.0 Ω Speciﬁes the upper threshold value of the impedance that is detected. If the speciﬁed value

is exceeded, it will be determined that the output has been interrupted.

Detect ImpMin 0.0–250.0 Ω Speciﬁes the lower threshold value of the impedance that is detected. If the measurement

falls below the speciﬁed value, it will be determined that the output has been interrupted.

Detect TH -17.8–22.22 dBu Speciﬁes the lower threshold value of the level that is detected. If the measurement falls

below the speciﬁed value, it will be determined that the output has been interrupted.

Detect Time 0–100 s Specify the interval (in seconds) at which checking for interrupted output will occur. If the

value is shorter than the time required for one measurement (approx. 0.5–8.0 seconds), the

measurement time will take effect instead.

Detected Lvl — Indicates the current output level value.

Detected Imp — Indicates the current impedance value.

● Calibrate by Pilot Tone

This performs the measurements using a pilot tone generated by the amp.

● Calibrate by Prog Source

This performs the measurements by outputting an audio source (program source) other than the pilot tone.

Parameter name Range Explanation

Frequency Type 5 Hz & 20 kHz,

10 Hz & 20 kHz

Speciﬁes the center frequency (5 Hz or 10 Hz) for the low-frequency

component of the pilot tone that is output to the speaker. The high-fre-

quency component is ﬁxed at 20 kHz.

With the exception of Start and Apply, the parameters listed below are

displayed and edited separately for the high-frequency component

(High) and low-frequency component (Low).

Enable ON/OFF Turns pilot tone output on/off.

Calibration Start Start Starts detection of level and impedance.

Detected Lvl — Indicates the detected level.

Detected Imp — Indicates the detected impedance value.

Apply Apply Based on the detected level and impedance value, settings will be

made for the Output Signal Chain screen (page 27) parameters Fre-

quency Type, Tone Level, Detect ImpMax (double the detected imped-

ance value), Detect ImpMin (half the detected impedance value), and

Detect TH (the detected level divided by √2).

Parameter name Range Explanation

Calibration Start Start Starts detection of impedance.

Detected Lvl — Indicates the detected impedance value.

● Filter types

• PEQ

This is a conventional parametric equalizer.

• L.SHELF (Low Shelving)

Without attenuating the low frequencies, this ﬁlter applies a ﬁxed amount of attenuation to the region above the cutoff

frequency. 6 and 12 (dB/Oct) specify the amount of attenuation per octave.

• H.SHELF (High Shelving)

Without attenuating the high frequencies, this ﬁlter applies a ﬁxed amount of attenuation to the region below the cutoff

frequency. 6 and 12 (dB/Oct) specify the amount of attenuation per octave.

• HPF (High Pass Filter)

A gently (12 dB/Oct) diminishing curve will be applied to the lower frequencies.

• LPF (Low Pass Filter)

A gently (12 dB/Oct) diminishing curve will be applied to the higher frequencies.

• APF (All Pass Filter)

This ﬁlter modiﬁes only the phase, passing the signal at all frequencies. This is used to correct the phase at the crossover

band. APF 1st will invert the phase 0°–180° and APF 2nd will invert the phase 0°–360°. For APF 2nd, you can adjust the

Q setting.

• Horn EQ

CD (Constant Directivity) horn speakers have the characteristic of rolling-off the level of the high-frequency range.

Horn EQ is an equalizer that compensates for this characteristic. For this reason, the Gain is limited to 0 dB or higher,

and the Frequency is limited to 500 Hz or higher.

■ Output Level (Speaker Processor)

This adjusts the output level in a range of -∞ – +10 dB.

■ Mute On/Off (Speaker Processor)

Turns output muting on/off.

■ Limiter (Speaker Processor)

This compresses signals exceeding the threshold at ∞:1, preventing signals higher than the threshold level from being output.

■ Output Router

Here you can specify the routing for the slot output. For each slot output channel, you can select from the following four types

of output points. For details on output points, refer to “SIGNAL PATH Block Diagrams” (page 30).

Parameter name Range Explanation

On ON/OFF Turns the limiter on/off.

Threshold -54–0 dB Speciﬁes the threshold value for the limiter.

Attack Mode Fast, Mid, Slow, Manual Selects the attack speed of the limiter. If the Manual setting is selected,

use the Attack setting below to specify the attack time. If Fast/Mid/Slow

is selected, the attack time is speciﬁed roughly according to the HPF

cutoff frequency of Speaker Processor’s Crossover.

Fast : 1/4 wavelength of cutoff frequency

Mid : 1/2 wavelength of cutoff frequency

Slow : 1 wavelength of cutoff frequency

System Connection Examples

Here is an example of multiple ampliﬁers connected in a daisy-chain via analog audio signals or digital audio sig-

nals (e.g., AES/EBU).

In the case of analog connection, daisy-chain the [THRU] jack and [IN] jack.

In the case of digital connection (the standard AES-IO card), daisy-chain the [THRU] jack and [IN] jack, or the

[OUT] jack and [IN] jack. The [THRU] jack will output the input signal without change, and the [OUT] jack will

output the signal with processing applied.

In order to monitor and control the ampliﬁers from Amp Editor, use Ethernet cables to connect the computer to each ampliﬁer.

This allows you to monitor and control all of the amps in the workspace from a single computer.

In the case of digital connections, you’ll need to make word clock settings (page 20). Specify whether you want the slot’s

CH 1/2 to be the master clock, or turn Auto Scan Mode on.

System Connection Examples

■ Thru-output for digital connections

For digital connections (the standard AES-IO card), the “thru” output from the [IN] jack to the [THRU] jack will be a signal

that has passed through the buffer if the power is on, or a signal that bypasses the buffer if the power is off.

If the power is on, the signal is regenerated in the buffer, theoretically allowing daisy-chain connection of any number of units.

At this time, a slight latency occurs (40 nsec when operating at 96 kHz), but even if ten units are connected this will be only 400

nsec (a mere 0.14 mm when calculated as a difference in distance).

If the power is off (or if the power will not turn on because the ampliﬁer has malfunctioned), a relay circuit will bypass the

buffer and directly “thru-output” the input signal so that the signal to the daisy-chained ampliﬁers connected downstream is not

interrupted. At this time, there will be a slight interruption in the sound due to the switching of the relay circuit. (Power-on ➝

off will take approximately 200 ms, and power off ➝ on will take approximately 10 ms.)

■ Regarding digital connections

When using a digital connection (the standard AES-IO card), please note the following points regarding connection cables.

•You must use a 110Ω digital cable to make digital connections. Do not use an analog mic cable. Although the same XLR con-

nector as for analog connections is used, take care not to inadvertently connect a digital signal and analog signal.

•A high-quality 110Ω digital cable can be extended to approximately 100 meters when operating at 96 kHz (theoretically to

approximately 200 meters when operating at 48 kHz). However, this length cannot be guaranteed in some cases, due to dif-

ferences in cable quality and the number of connector contacts. Please use cables that are impedance-matched and have min-

imal attenuation through the high-frequency range (12 MHz).

• If you need to extend a digital cable longer than 100 meters, we recommend that you use an impedance conversion connector

to change from the 110Ω XLR connector to a 75Ω coaxial (BNC) connector, and use a 75Ω coaxial video cable to convey the

signal. Even in this case, the signal will be dependent on the quality of the cable, but can usually be extended up to 300

meters.

• As far as possible, connect the digital cable directly to the TXn ampliﬁer itself without routing it through a patch panel on

your amp rack, etc. Routing the signal via a patch panel will make impedance matching more difﬁcult.

• If you want to distribute a digital signal to multiple ampliﬁers, we recommend that you use the TXn’s “thru” output to make

daisy-chain connections, or distribute it using an external device (such as a digital mixer in which an AES/EBU card is

installed, or a DME series unit). Using a parallel cable to distribute the signal cannot be recommended from the viewpoint of

impedance matching.

System Connection Examples

By connecting both the analog audio signal and the digital audio signal, you can make a redundant connection

(duplicate audio connections). If the digital audio signal is interrupted by a problem such as a broken connection,

the system will switch to the analog audio signal.

In order to enable a redundant connection, you’ll need to access the MENU screen ➝ General ➝ Input Redun-

dancy, and choose “Backup” so that the digital audio signal has priority (page 26).

You can connect a lamp etc. to the rear panel [FAULT OUTPUT] connector to

indicate that an abnormality has occurred.

The [FAULT OUTPUT] connector consists of NO (Normally Open), C (Common), and

NC (Normally Closed). The [FAULT OUTPUT] connector is a relay circuit, and oper-

ates as follows.

The relay contacts used in the [FAULT OUTPUT] connector are rated for a load of 1A, DC 30V. Do not apply a load that

exceeds this rating.

Use Amp Editor to make settings for the [FAULT OUTPUT] connector.

Euroblock plugs are used for the [FAULT OUTPUT] connector. Euroblock connection methods are described in “Euroblock

● Cable preparation

•To prepare the cable for attachment to a Euroblock connector, strip the wire as

shown in the illustration, and use stranded wire to make connections. With a

Euroblock connection, the stranded wire may be prone to breakage because of

metal fatigue due to the weight of the cable or due to vibration. When rack-mount-

ing your equipment, use a lacing bar when possible to bundle and fasten the cables.

• If cables will be frequently connected and disconnected, as in the case of a portable

installation, we recommend that you use ferrules with insulation sleeves. Use a fer-

rule whose conductor portion has an external diameter of 1.3 mm or less, and a

length of approximately 5 mm (such as the AI0,5-6WH made by the Phoenix Con-

tact corporation).

• If you use stranded wire, do not tin (plate with solder) the exposed end.

TX6n/5n/4n Reference Manual

Adjusting the Input/Output Levels

■ Basic level adjustment

If we think of the TXn ampliﬁer in a similar way as a conventional analog ampliﬁer, there are two parameters that determine the

gain/level.

• Gain / Input sensitivity:

The input level before A/D conversion is adjusted from the front panel MENU screen ➝ [General] ➝ [Sensitivity/Amp

Gain].

If the level is not modiﬁed within the internal DSP (SIGNAL PATH), the gain / input sensitivity can be thought of as

being exactly the same as on a conventional analog ampliﬁer. The gain can be adjusted in a range of 19.8 to 43.8 dB in 0.1

dB increments. However, the input sensitivity range differs between models.

• Attenuator:

The output level at the ﬁnal stage after D/A conversion can be adjusted by turning encoders A/B in the HOME screen.

The range is 0.0 to -80.0 and -∞dB, adjustable in 0.5 dB increments.

Unlike a conventional analog ampliﬁer, the level can also be adjusted using the 4x4 Matrix Mixer or Speaker Processor of the

internal DSP (SIGNAL PATH screen). These can be used as appropriate for different purposes. For example, the Speaker Pro-

cessor can be used to adjust the level for each speaker unit.

■ Level adjustments between TX6n/TX5n/TX4n units

In a system where different TX6n/TX5n/TX4n models coexist, set the same gain on each unit if you want to obtain the same

output level (V, dBu) for a given input level. These settings are convenient when you need to manage the gain in a multi-way

speaker system. In this case, the maximum output will differ depending on the model, meaning that as you raise the input level,

the power amp section of the TX5n and TX4n will clip earlier than the TX6n.

Conversely, if you want to obtain the maximum output power (W) from the ampliﬁers for a given maximum input level, set the

input sensitivity to match the maximum input level. In this case, the output level for a given input level will differ depending on

the model, but each ampliﬁer’s maximum output will be obtained for the same input level (the power amp section will begin

clipping when the maximum input occurs).

■ Level adjustments between analog and digital

To match the digital signal level to the analog signal level

without changing the analog signal level, adjust the gain of the

slot input.

If you want the level to be consistent between analog and dig-

ital signals from an audio source (such as a digital mixer)

equipped with both analog and digital outputs, refer to “Gain /

Input Sensitivity conversion table” (page 53). Set the gain so

that even when using the TX5n or TX4n, the input sensitivity

of the TX6n and the maximum analog output level of the

audio source are equivalent.For example, the Yamaha PM5D

features a maximum output level of +24 dBu, so in this case

you would set the ampliﬁer’s gain to 19.8 dB.The DM2000 or

the MY8-DA96 card have a maximum output level of +18

dBu, so in this case you would set ampliﬁer’s gain to 25.8

dB.With these settings, the digital full-bit will be equivalent to

the audio sources’ analog maximum output level.

explains operation and specifications for the TX6n, TX5n, and TX4n (subsequently referred to as TXn) power amplifiers. When using the TXn, you will also need to consult various manuals other than this document. ● Manuals other than this document TX6n/5n/4n Owner’s Manual (printed) Explains mainly the initial setup. Amp Editor Installation Guide (PDF) Explains the installation procedure for Amp Editor and the uninstallation procedure. Amp Editor Owner’s Manual (PDF) Explains how to use Amp Editor. PDF manuals and Amp Editor can be downloaded from the following URL. http://www.yamahaproaudio.com/ NOTE • In order to view the downloaded manuals, Adobe Reader must be installed in your computer. If you don’t have Adobe Reader, please access the Adobe Corporation’s website at the following URL, and download Adobe Reader (free of charge). http://www.adobe.com/ Setup For details on setting up the TXn and Amp Editor, refer to the “TX6n/5n/4n Owner’s Manual” and “Amp Editor Owner’s Manual.” TX6n/5n/4n Reference Manual 3 Introduction Terms This section explains terminology specific to the TXn. ■ Amp Editor This is computer application software. This software allows you to monitor and control the TXn amplifiers from your computer. ■ Scene Settings such as power-on/standby or mute for each amplifier are called a “scene.” By recalling a scene, the saved settings can be immediately applied to the amplifiers. Each TXn unit has 50 scenes. ■ Signal Path This is the audio signal processing functionality provided by the internal DSP. Components organized into modules according to their functionality are placed in the signal path. ■ Component These are modules in the signal path that organize audio signal processing according to their functionality. ■ Library The settings of all Speaker Processor components can be saved together in a library. A library can be saved only from Amp Editor, but can be recalled from the unit’s front panel as well. ■ Device ID This is an ID for uniquely identifying a TXn unit within a network. In order to allow monitoring and control from Amp Editor, you must specify non-conflicting IDs within a workspace. 4 TX6n/5n/4n Reference Manual Controls and Connectors Front Panel !9 @0 !9 @0 i i !4 o !0 e !2 r q t y u q w o !1 !1 !0 !2 !5 !3 !6 !7 !8 !3 q [POWER] switch and indicator This switch turns the amplifier’s power on or off. When you turn this switch on, the [POWER] indicator will light white. In Standby mode, it will light white as well. w [STANDBY] indicator This indicator will light orange when the amplifier’s power is in Standby mode. To switch between Standby/On modes, hold down the TXn’s panel [HOME] button for three seconds or longer, or switch the mode from the MENU screen ➝ General ➝ Sensitivity/Amp Gain or Amp Editor’s Detail View window. NOTE • Standby is a state in which the speaker output’s power amp section is off (operation other than speaker output will continue). e [IDENTIFY] indicator When you click the [Identify] button in the Tree View window of Amp Editor, the [IDENTIFY] indicator of the corresponding amplifier will blink blue. r [NETWORK] indicator This will blink green when the amplifier is connected to a computer via the [NETWORK] connector, and data is being sent or received. TX6n/5n/4n Reference Manual 5 Controls and Connectors t [PROTECTION] indicator When the protection system is active, this indicator will light red. The protection circuit will operate in the following situations. • If the amplifier overheats and the output limiter operates The speaker output will be attenuated if the heat sink of the amplifier section exceeds 80°C (80%), and will be muted if the heat sink exceeds 90°C (90%). The [PROTECTION] indicator will light at 80°C (80%) or higher. • If the power supply overheats and shuts-down The fan will rotate at high speed if the power supply section exceeds 90°C, and the analog circuits will shut down if it exceeds 100°C. The [PROTECTION] indicator will light only if shut-down occurs. NOTE • The thermal meter in the METER screen and in Amp Editor indicates the heat sink temperature of the amp section. The temperature of the power supply section is not shown. • If the load falls below 0.5 ohms If a short occurs and the load falls below 0.5 ohms, the speaker output will be muted, and muting will be cleared approximately 1 second later. • If DC output is detected The speaker output will be muted, and the power supply section will shut down. • If the power supply malfunctions The speaker output will be muted. • If ultra-high frequencies, overcurrent, excessive total current, or maximum current is detected The speaker output will be compressed. y [BRIDGE] indicator This will light green if the amplifier mode is set to Bridge. u [PARALLEL] indicator This will light orange if the amplifier mode is set to Parallel. i [MUTE] indicator This indicator will light red if muting is turned on by the [MUTE] button or from Amp Editor. When the power is turned on, the output signal will also be muted and the indicator will blink red until audio begins being output. NOTE • Even if mute is off, this indicator will blink if Solo was turned on from Amp Editor, or when the output has been muted by the protection circuit. o [MUTE] button By holding down the [MUTE] button for one second or longer, you can turn muting on/off for that channel. When muting turns on, the [MUTE] indicator will light. By holding down the [MUTE] button when the Solo function is turned on from Amp Editor, Solo will be defeated. !0 [ALERT] indicator This will light to indicate an alert related to the amplifier’s audio signal. If an alert for a specific channel has occurred, the indicator of the corresponding channel will light; for other alerts, the indicators of both channels will light. At this time, the alert message will appear in the upper part of the display. !1 [CLIP] indicator When the signal of the speaker output’s power amp section exceeds the clipping level, this indicator will light and the output signal will be compressed. !2 [SIGNAL] indicator This will light green when the level of the signal being output from the [SPEAKERS] jack exceeds 1 Vrms (equivalent to 0.2 W into an 8 ohms load, 0.4 W into a 4 ohms load or 0.8 W into a 2 ohms load). 6 TX6n/5n/4n Reference Manual Controls and Connectors !3 Encoders A, B When the display shows the attenuation meter, these encoders adjust the attenuation of channels A and B. If any other screen is displayed, encoder A moves the cursor and encoder B modifies the parameter value. NOTE • Only encoder A can be operated if you’re adjusting the attenuation when the amplifier mode is Bridge. !4 Display This shows the amplifier’s settings or a level meter. Refer to “Screen Structure” (page 13) for details. NOTE • If the power supply is in Standby mode or if the LCD Setup’s Backlight setting is Auto OFF, the backlight will go dark if no panel operation has been performed for ten seconds. It will light again when a panel operation is performed. !5 Function buttons These buttons move to the screen indicated above each button in the display. If a channel name (e.g., CH A, CH B) is shown, this means that a parameter for that channel is displayed; press the corresponding function button to switch the channel that is shown. These buttons may also operate in different ways depending on the screen shown in the display. !6 [HOME] button This accesses the HOME screen (page 15) in the display. By holding down this button for three seconds or longer, you can switch the power between Standby and On modes. When the confirmation message appears, press the [ENTER] button to switch the setting. !7 [EXIT] button By pressing this button when the display shows a screen other than the HOME screen, you can move to the screen of the next highest level. NOTE • To temporarily disable panel lock, simultaneously hold down the [HOME] button and [EXIT] button for three seconds or longer. • If you hold down this button for three seconds or longer in the HOME screen, the FAULT OUTPUT connector output will be reset (NC and C will be connected). !8 [ENTER] button Use this to select a parameter or to finalize an edited parameter value. Depending on the screen shown in the display, this button may also be used in other ways. If the parameter value is blinking, you must finalize the value by pressing this button. NOTE • If you hold down this button for one second or longer in the HOME screen, the UTILITY screen Device Setup page (page 19) will appear. !9 Air intakes The amplifier uses forced-air cooling. The variable speed cooling fan draws air in from the front and exhausts it through the rear. The cooling fan speed varies depending on the heat sink temperature: It operates at low speed when it is below 40 °C (40%), increases in speed according to increases in temperature, and operates at high speed when temperature exceeds 60 °C (60%). If the power supply exceeds 90°C, the variable speed fan will operate at high speed regardless of the heat sink temperature. Please be sure that you do not block the air intakes or exhaust vents. Also, clean the filter elements regularly. If the air intakes are clogged with dust or debris, the amplifier will overheat, which may result in the amplifier shutting down. @0 Screw holes for handles These four screw holes (four locations) are for the included handles. Fix the handles to the amplifier, using the included flathead screws. TX6n/5n/4n Reference Manual 7 Controls and Connectors Rear Panel @1 @2 @7 @4 @6 @5 @3 @1 [SPEAKERS] jacks These are speaker output jacks. • Speakon connectors : Speakon type cable plugs (Neutrik NL4) can be connected here. • Five-way binding post connectors : Bare wires or Y plugs can be connected here. NOTE • The five-way binding post connectors and Speakon connectors are internally connected in parallel. If you’re using both simultaneously, make sure that the speaker impedance of each connector is 4–16 ohms (8–32 ohms in Bridge mode). @2 Digital input/output connectors (I/O card slot) An AES-IO card is installed as standard, allowing AES/EBU digital audio signals to be input and output. • [IN] connector : This is an XLR-3-31 type balanced input connector for inputting two-channel digital audio signals. • [OUT] connector : This is an XLR-3-32 type balanced output connector for outputting two-channel audio signals processed by the internal DSP. • [THRU] connector : This is an XLR-3-32 type balanced output connector that outputs the unprocessed signal received at the [IN] connector. Even if the power is turned off, this connector will output the input signal without any change (page 44). However, internal settings will be switched when the power is switched on/off, causing the output signal to be muted for an instant. NOTE • If desired, you can remove the AES-IO card and install a separately sold MY card. For details on the types of MY card that can be used and how to install them, refer to “Optional I/O cards” (page 9). • The removed AES-IO card cannot be installed and used in other devices. • You must use a 110 ohm digital cable to make AES/EBU connections. @3 Analog input/output connectors These connectors input and output analog audio signals. • [IN] connector : These are XLR-3-31 type input connectors for inputting analog audio signals. The pin polarity is shown at right (IEC 60268). NOTE • In Parallel mode and Bridge mode, only the signal of channel A is output from the speaker output connector by default. The channel B signal is not sent from the speaker output, but the audio signal processed by the internal DSP can be output from the digital output connector. • [THRU] connector : This is an XLR-3-32 type balanced output connector that outputs the unprocessed analog signal received from the [IN] connector. 8 TX6n/5n/4n Reference Manual Hot Ground Cold Controls and Connectors @4 [NETWORK] connector This is a 100BASE-TX/10BASE-T Ethernet connector. You can connect this to a computer so that the amplifier can be monitored and controlled from Amp Editor. This also allows an external controller such as AMX or Crestron to be connected. NOTE • To prevent electromagnetic interference, use an STP (Shielded Twisted Pair) cable for the [NETWORK] connector. @5 [FAULT OUTPUT] connectors This is a 3P Euroblock connector for controlling an external analog device when an abnormality occurs in the CPU or triggered by the occurrence of a Fault event specified in Amp Editor. NC and C will be connected when the amplifier is operating normally; NO and C will be connected when a problem occurs (page 51). You can also reset this output from Amp Editor. A message will appear in the screen if a problem occurs. To reset the output, hold down the [EXIT] button for three seconds or longer in the HOME screen. @6 Power cable Connect the plug of the power cable to an AC outlet of the correct voltage. @7 Grounding screw The AC power cord is a 3-wire type. If the AC outlet used is earthed (grounded), this device will be properly earthed as well. Also, grounding the screw sometimes reduces hum and interference noise. Optional I/O cards ■ Supported I/O cards You can remove the AES-IO card from the TXn’s rear panel, and install a separately sold MY (mini-YGDAI) card.

CAUTION TX6n/5n/4n Reference Manual 43 System Connection Examples Daisy-chain connection via analog or digital audio Here is an example of multiple amplifiers connected in a daisy-chain via analog audio signals or digital audio signals (e.g., AES/EBU). In the case of analog connection, daisy-chain the [THRU] jack and [IN] jack. In the case of digital connection (the standard AES-IO card), daisy-chain the [THRU] jack and [IN] jack, or the [OUT] jack and [IN] jack. The [THRU] jack will output the input signal without change, and the [OUT] jack will output the signal with processing applied. Computer Amp Editor Amp control Amp control Amp control Network switch Amp control Analog audio or Digital audio Analog audio or Digital audio THRU/ OUT IN TXn Analog audio or Digital audio THRU/ OUT IN TXn IN TXn Mixer In order to monitor and control the amplifiers from Amp Editor, use Ethernet cables to connect the computer to each amplifier. This allows you to monitor and control all of the amps in the workspace from a single computer. In the case of digital connections, you’ll need to make word clock settings (page 20). Specify whether you want the slot’s CH 1/2 to be the master clock, or turn Auto Scan Mode on. 44 TX6n/5n/4n Reference Manual System Connection Examples ■ Thru-output for digital connections For digital connections (the standard AES-IO card), the “thru” output from the [IN] jack to the [THRU] jack will be a signal that has passed through the buffer if the power is on, or a signal that bypasses the buffer if the power is off. DIGITAL (AES/EBU) IN THRU Relay Relay Buffer If the power is on, the signal is regenerated in the buffer, theoretically allowing daisy-chain connection of any number of units. At this time, a slight latency occurs (40 nsec when operating at 96 kHz), but even if ten units are connected this will be only 400 nsec (a mere 0.14 mm when calculated as a difference in distance). If the power is off (or if the power will not turn on because the amplifier has malfunctioned), a relay circuit will bypass the buffer and directly “thru-output” the input signal so that the signal to the daisy-chained amplifiers connected downstream is not interrupted. At this time, there will be a slight interruption in the sound due to the switching of the relay circuit. (Power-on ➝ off will take approximately 200 ms, and power off ➝ on will take approximately 10 ms.) ■ Regarding digital connections When using a digital connection (the standard AES-IO card), please note the following points regarding connection cables. • You must use a 110Ω digital cable to make digital connections. Do not use an analog mic cable. Although the same XLR connector as for analog connections is used, take care not to inadvertently connect a digital signal and analog signal. • A high-quality 110Ω digital cable can be extended to approximately 100 meters when operating at 96 kHz (theoretically to approximately 200 meters when operating at 48 kHz). However, this length cannot be guaranteed in some cases, due to differences in cable quality and the number of connector contacts. Please use cables that are impedance-matched and have minimal attenuation through the high-frequency range (12 MHz). • If you need to extend a digital cable longer than 100 meters, we recommend that you use an impedance conversion connector to change from the 110Ω XLR connector to a 75Ω coaxial (BNC) connector, and use a 75Ω coaxial video cable to convey the signal. Even in this case, the signal will be dependent on the quality of the cable, but can usually be extended up to 300 meters. • As far as possible, connect the digital cable directly to the TXn amplifier itself without routing it through a patch panel on your amp rack, etc. Routing the signal via a patch panel will make impedance matching more difficult. • If you want to distribute a digital signal to multiple amplifiers, we recommend that you use the TXn’s “thru” output to make daisy-chain connections, or distribute it using an external device (such as a digital mixer in which an AES/EBU card is installed, or a DME series unit). Using a parallel cable to distribute the signal cannot be recommended from the viewpoint of impedance matching. TX6n/5n/4n Reference Manual 45 System Connection Examples Redundant connections (Backup) By connecting both the analog audio signal and the digital audio signal, you can make a redundant connection (duplicate audio connections). If the digital audio signal is interrupted by a problem such as a broken connection, the system will switch to the analog audio signal. In order to enable a redundant connection, you’ll need to access the MENU screen ➝ General ➝ Input Redundancy, and choose “Backup” so that the digital audio signal has priority (page 26).

CAUTION TX6n/5n/4n Reference Manual 51 Connecting External Controllers and Analog Devices Euroblock plug connection Use the included Euroblock plug (3P) to make connections to the [FAULT OUTPUT] connector. ● Cable preparation • To prepare the cable for attachment to a Euroblock connector, strip the wire as shown in the illustration, and use stranded wire to make connections. With a Euroblock connection, the stranded wire may be prone to breakage because of metal fatigue due to the weight of the cable or due to vibration. When rack-mounting your equipment, use a lacing bar when possible to bundle and fasten the cables. • If cables will be frequently connected and disconnected, as in the case of a portable installation, we recommend that you use ferrules with insulation sleeves. Use a ferrule whose conductor portion has an external diameter of 1.3 mm or less, and a length of approximately 5 mm (such as the AI0,5-6WH made by the Phoenix Contact corporation). • If you use stranded wire, do not tin (plate with solder) the exposed end. CAUTION 1. Loosen the terminal screws. NOTE • Use a slotted screwdriver with a blade approximately 2 mm wide. Slotted screwdriver 2 mm Loosen Euroblock plug Terminal screw 2. Insert the cables. 3. Securely tighten the terminal screws. Pull the cables (not too strongly) to confirm that they are securely connected. 4.

level adjustment If we think of the TXn amplifier in a similar way as a conventional analog amplifier, there are two parameters that determine the gain/level. • Gain / Input sensitivity: The input level before A/D conversion is adjusted from the front panel MENU screen ➝ [General] ➝ [Sensitivity/Amp Gain]. If the level is not modified within the internal DSP (SIGNAL PATH), the gain / input sensitivity can be thought of as being exactly the same as on a conventional analog amplifier. The gain can be adjusted in a range of 19.8 to 43.8 dB in 0.1 dB increments. However, the input sensitivity range differs between models. • Attenuator: The output level at the final stage after D/A conversion can be adjusted by turning encoders A/B in the HOME screen. The range is 0.0 to -80.0 and -∞dB, adjustable in 0.5 dB increments. Unlike a conventional analog amplifier, the level can also be adjusted using the 4x4 Matrix Mixer or Speaker Processor of the internal DSP (SIGNAL PATH screen). These can be used as appropriate for different purposes. For example, the Speaker Processor can be used to adjust the level for each speaker unit. ■ Level adjustments between TX6n/TX5n/TX4n units In a system where different TX6n/TX5n/TX4n models coexist, set the same gain on each unit if you want to obtain the same output level (V, dBu) for a given input level. These settings are convenient when you need to manage the gain in a multi-way speaker system. In this case, the maximum output will differ depending on the model, meaning that as you raise the input level, the power amp section of the TX5n and TX4n will clip earlier than the TX6n. Conversely, if you want to obtain the maximum output power (W) from the amplifiers for a given maximum input level, set the input sensitivity to match the maximum input level. In this case, the output level for a given input level will differ depending on the model, but each amplifier’s maximum output will be obtained for the same input level (the power amp section will begin clipping when the maximum input occurs). ■ Level adjustments between analog and digital To match the digital signal level to the analog signal level without changing the analog signal level, adjust the gain of the slot input. If you want the level to be consistent between analog and digital signals from an audio source (such as a digital mixer) equipped with both analog and digital outputs, refer to “Gain / Input Sensitivity conversion table” (page 53). Set the gain so that even when using the TX5n or TX4n, the input sensitivity of the TX6n and the maximum analog output level of the audio source are equivalent.For example, the Yamaha PM5D features a maximum output level of +24 dBu, so in this case you would set the amplifier’s gain to 19.8 dB.The DM2000 or the MY8-DA96 card have a maximum output level of +18 dBu, so in this case you would set amplifier’s gain to 25.8 dB.With these settings, the digital full-bit will be equivalent to the audio sources’ analog maximum output level. 54 TX6n/5n/4n Reference Manual Redundancy [Analog Input A] ADC Pol.
