Precautions
User’s Guide
Precautions
1 Avoid excessive heat, humidity, dust, and vibration.
Keep the MT4X away from locations where it is likely to be
exposed to high temperatures or humidity, such as direct
sunlight, near radiators, stoves, etc. Also avoid locations which
are subject to excessive dust accumulation or vibration which
could cause mechanical damage.
2 Avoid physical shocks
Strong physical shocks can cause damage. Handle the unit with
care.
3 Clean with a soft dry cloth
Never use solvents such as benzine or thinner to clean the
MT4X. Wipe it clean with a soft dry cloth.
4 Do not open the case or attempt repairs or modification
yourself
The MT4X contains no user-serviceable parts. For other than
routine cleaning, refer all maintenance to qualified YAMAHA
service personnel. Opening the case and/or tampering with the
internal circuitry will void the warranty.
5 Make sure power is off before making or removing
connections
Always turn the power OFF prior to connecting or
disconnecting cables. This will prevent damage to the MT4X as
well as other connected equipment.
6 Handle cables carefully
Always plug and unplug cables — including the AC cord — by
gripping the connector, not the cord.
7 Always use the correct power supply
The MT4X is sold configured to the appropriate power
specifications for the local area. The power supply voltage and
power consumption are listed on the bottom panel. If you move
to an area with a different AC mains voltage, be sure to check
with your nearest YAMAHA dealer before using the unit.
8 Keep the heads and tape path clean
To ensure consistent high performance and sound quality from
the MT4X, it is important to clean the heads and tape path
regularly — ideally before each recording session. Use a
cleaning kit specifically designed to use with cassette tape
equipment.
9 Use only high-quality chrome cassette tape
The MT4X is designed to be used with Chrome tape (CrO
2
tape
— Bias: HIGH or TYPEII position; EQ: 70
µ
s). It will not work
properly with Ferrichrome tape formulations. You may
experience high frequency distortion if you use such tapes.
The use of tapes longer than 90 minutes (C-120 and longer) is
not recommended. These tapes are much thinner and therefore
prone to poor performance or failure.
TDK SA 46 – 90 and Maxell XLII 46 – 90 are recommended.
10 Handle the cassette tapes properly
You should fast forward and rewind new tapes before you
record on them. This will prevent any possible binding that
could be caused by the tape being tightly wound at the factory.
It is best not to use the first and last 20 seconds of a tape. The
splice between the leader and the tape can cause distortion.
When loading a cassette, check that the tape is not loose, then
load the tape firmly into the cassette compartment. If the tape is
not loaded properly, the unit may jam or otherwise malfunction.
11 Use the dbx™ switch correctly
To obtain the best possible sound quality, you should always use
the dbx™ noise reduction system to playback tapes that were
recorded with the dbx™ system on. If the tape was recorded
without dbx™, turn the noise reduction system off.
The dbx™ noise reduction system was manufactured based on a
patent licence from THAT Corporation. dbx is a trademark of
Carillion Electronics Corporation.

User’s Guide
Introduction
Your MT4X Multitrack Cassette recorder is a powerful recording tool that will allow you to capture your
music at a very high level of sound quality. It is an advanced technology, easy-to-use four-track cassette
tape recorder with a comprehensive four-channel mixer.
In order to make use of the many features of the MT4X and to obtain the best performance, please read this
manual thoroughly — and keep it in a safe place for future reference.
Features
General
The MT4X consists of a four-channel mixer section and a four-track cassette tape recorder section inside a
compact enclosure. Independent recording and playback is possible for each track. This allows you to
create high-quality multi-track recordings.
Mixer
The mixer section is equipped with independent stereo buses for greater flexibility.
Continuously variable gain controls are provided for each input channel. These can be used with any
input source, from microphones to electronic instruments.
Each channel has a three band equalizer (HIGH, MID, and LOW) giving you flexible tone-shaping
capabilities.
Dual AUX SEND and AUX RETURN (stereo) connectors allow you to add effects from external signal
processors. You can assign the AUX RETURN signal to each channel as required.
Recorder
The dbx
noise reduction system provides substantial noise reduction and a wide dynamic range.
An automatic punch-in/out recording function and a rehearsal function make recording easier and
more accurate. Locate functions, such as memory and return-to-zero are provided for additional
convenience.
A large, multi-functional display shows the recording and playback levels, along with a tape counter
and other indicators, giving you immediate and helpful information about the status of the MT4X.
The pitch control allows you to vary the tape speed with in a range of approximately
±
10%. This can be
useful when you have to compensate for pitch variations during an overdub.
The tape transport is a full-logic mechanism, making recording and playback operation smooth and
simple.
The transport offers two speeds: 9.5 cm/sec and 4.8 cm/sec.

User’s Guide
Structure of the MT4X
The MT4X can be divided into three basic sections – the mixer, the recorder, and the bus lines which
connect them:
Mixer
The mixer has four input channels. It adjusts the input signals at each respective channel and sends them
to the bus lines.
The signals input to each channel of the mixer can be switched to either input signals (MIC/LINE) or
playback signals (TAPE). When TAPE is selected, the playback signal from each track is input to the
corresponding channel. The tone of the signal is adjusted through the equalizer and the volume at the
channel faders. It is then sent to the bus lines using the ASSIGN keys and PAN control.
Bus Lines
There are four main bus lines (group buses) which receive the input signals from each respective channel
of the mixer. If signals from two or more input channels are sent to a bus line, these signals are overlaid or
mixed.
There is also a STEREO bus (L, R), an AUX bus (1, 2), and a CUE bus.
Recorder
The signals from the bus lines are recorded by the cassette recorder. It also sends the signal to the
TAPE OUT connectors and back to the mixer (including the CUE bus).
Also refer to the "Block Diagram" on page 48.

3 Recording Functions
The basic functions of multitrack recording are as follows:
Monitoring
The MT4X offers you a great deal of flexibility in monitoring the status of your recordings. You can
monitor the individual channel groups, the stereo bus, the cue bus, or any combination.
Of these three monitor sources, you will probably find the cue bus is the most useful. This bus allows you
to monitor the previously recorded tracks as well as new material independently of the mixer section. It is
sometimes very important to be able to listen directly to the tracks, for example, to compare different
mixer settings to the original signal.
You adjust the overall monitoring level with the MONITOR/PHONES control.
Monitoring
Monitoring the recording or playback to listen for mistakes or
unwanted distortion.
Initial recording
Recording the first instrument or part.
Overdub recording
Recording additional instruments or parts while monitoring the
previously recorded tracks.
Punch-in/out recording
Correct mistakes or add short segments to an existing track.
Ping-pong recording
Bounce several existing tracks onto another track.
Mixdown
Mix the results of your multitrack recording onto a stereo master
tape.
You control monitoring with the MONITOR SELECT keys
0
:
GROUP
The GROUP keys allow you to monitor the group bus signals. If you only
press one key, you will hear monaural output. If you press both keys, you will
hear groups 1 and 3 in the left channel and groups 2 and 4 in the right channel.
The signals on the group buses go directly to the recorder.
STEREO
The STEREO key allows you to monitor the stereo bus signal. You can monitor
the signals from the four input channels as well as the AUX RETURN signal.
Some of these signals may not have been assigned to the group bus, allowing
you to listen to signals that will not be recorded.
CUE
The CUE key allows you to monitor the playback signals directly from the
cassette tracks. You can set the volume for each track with the CUE LEVEL
controls. The cue bus is monaural.
When you are recording, the record signal is monitored.

Initial recording
The first step in multitrack recording is to record the initial tracks. Usually, these are your rhythm tracks:
bassguitar, rhythm guitar, and drums.
Preparations for recording
1) Insert a cassette tape into the cassette tape compartment (
D
).
2) Connect the input source to the corresponding MIC/LINE INPUT connector for each channel.
3) Set the input select key (
6
) to the MIC/LINE position.
4) Rotate the GAIN control (
1
) to adjust the initial level of the input signal.
If you have plugged a microphone into the corresponding connector, rotate the control fully
clockwise to the MIC setting.
If you have plugged a synthesizer into the connector, or are running a bassguitar or guitar through a
signal processor (line level output), rotate the control fully counter-clockwise to the LINE setting.
Note:
Before you record anything, you must connect the MT4X to both an input source and a monitoring
system. See "Example System" on page 14.
Note:
This level setting is temporary — just to get a rough signal level based on the type of input you have
connected. Be aware that you could easily be sending a signal that is overloading the gain amplifier and
causing distortion. To set the final level, see steps 10 and 11.

5) Using the ASSIGN keys (
4
) and the PAN control (
5
) select the group bus you want the input
signal to go to.
If the PAN control is set to a position partway between L/ODD and R/EVEN, the input signal will
be sent to both the odd and even group buses.
If you press both ASSIGN keys, the input signal will be sent to at least two group buses.
6) Press the REC SELECT keys (
G
) for the tracks you want to record.
The corresponding REC SELECT - TRACK indicator (
c
) on the display will flash.
Press the REC SELECT key again to cancel the selection.
7) Press the MONITOR SELECT - CUE key (
0
). Adjust the CUE LEVEL controls (
A
) for the selected
tracks. Set the monitor volume with the MONITOR/PHONES level control (
B
).
8) Press the COUNTER RESET key (
Q
) to set the tape counter (
Y
) to “0000”.
Set the recording levels
In order to obtain the best possible sound quality, it is very important to set optimal recording levels. If
you set the levels too low, you will be able to notice tape noise. If you set the levels too high, the tape will
be saturated and distortion will result. Therefore, you should set the recording levels to the highest level
before distortion sets in.
The MT4X is equipped with sensitive peak-hold level meters (
Z
). You can monitor the level of the
individual tracks and the stereo bus. Use the level meters in conjunction with the monitoring modes (see
"Monitoring" on page 15) to set your recording levels.

11) Adjust the GAIN control while watching the level meters.
When dbx™ is off, adjust the gain control so that the +3 dB segment occasionally illuminates.
When dbx™ is on, adjust the gain control so that the +9 dB segment occasionally illuminates.
Record the track
12) Press the PLAY key (
T
).
The indicator above the key lights and the MT4X starts the tape. Start playing.
13) When the track is complete, press the RETURN TO ZERO key (
I
) to stop and rewind the tape.
The indicators above the REC/PAUSE and PLAY keys switch off and the REC SELECT - TRACK
indicators resume flashing.
Check the completed recording
Once the tape has rewound back to “0000” on the tape counter, you should check the recording.
14) Press the PLAY key to playback the tape.
15) If the recording needs to be redone, repeat the previous steps.
If the problem with the recording was a musical error, press the REC/PAUSE key and repeat
steps 12 to 14.
If the problem was due to incorrect recording levels or other engineering problems, adjust the
parameters by repeating steps 4 to 14.
16) When you are finished with an instrument, you should set the channel fader to “0”. You may even
want to disconnect the input source.
Note:
The meters display a range of -20 dB to +9 dB. If the meters exceed the normal limit momentarily, this is
usually perfectly acceptable. Cassette tape is reasonably forgiving of transients – and human hearing has difficulty
detecting the minor distortion that results. Where you start getting audible problems is when the meters are
constantly above the normal limit. You must lower the levels in order to maintain decent sound quality.
Note:
The MT4X can recall and display the maximum recording levels obtained during a session. See
"Recording Levels Function" on page 42.
Tip:
If your song starts with drums, bassguitar, and guitars all on the first bar, you will need to record a
count-in.
Tip:
You may want to use the STOP key (
W
) to stop the tape and mark a memory point. See "Memory
Functions" on page 41.

Overdubbing
Overdub recording is the basis of all multi-track recording. It enables you to record additional instruments
or parts track-by-track while listening to the previously recorded tracks.
Preparations for recording
1) Connect the input source for each channel to the corresponding
MIC/LINE INPUT connector.
2) Set the input select key to the MIC/LINE position.
3) Rotate the GAIN control to adjust the level of the input signal.
4) Using the ASSIGN keys and the PAN control select the group bus you want the input signal to go to.
5) Press the REC SELECT keys for the tracks you want to record.
The corresponding REC SELECT - TRACK indicator on the display will flash.
6) Press the MONITOR SELECT - CUE key.
7) Press the PLAY key to playback the tape. As the tape plays, adjust the CUE LEVEL controls for the
selected tracks. Set the monitor volume with the MONITOR/PHONES level control.
8) Press the RETURN TO ZERO key to rewind the tape back to “0000” on the tape counter.
Set the recording levels
9) Press the REHE key (
R
).
The indicator above the key lights and any flashing REC SELECT - TRACK indicators will be
illuminated.
10) Set the channel fader to the nominal level between “7” and “8” and adjust the GAIN controls.
Note:
Connecting an instrument with a high output impedance such as an electric guitar or bassguitar
to the MT4X may increase noise and distortion. If this happens, connect a direct box or effect unit between
the instrument and the MT4X to reduce the impedance.

14) Press the PLAY key.
The indicator above the key lights and the MT4X starts the tape. Play the part again.
15) When the track is complete, press the RETURN TO ZERO key to stop and rewind the tape.
The indicators above the REC/PAUSE and PLAY keys switch off and the REC SELECT - TRACK
indicators resume flashing.
Check the completed recording
16) Press the PLAY key to playback the tape and check the recording.
17) If the recording needs to be redone, repeat the previous steps.
Tip:
Sometimes the pitch of an instrument and the pitch of the previously recorded tracks is slightly
different. If you cannot adjust the pitch of the instrument, you can compensate for the error with the TAPE
SPEED CONTROL (
F
) - PITCH control. The PITCH control can adjust the tape speed by approximately
±
10%. During rehearsal, adjust the PITCH control until you have matched the instrument with the tracks.
Note:
To prevent wow and flutter effects, do not accidentally adjust the PITCH control while you are
recording.

To overdub another part, simply repeat steps 1 to 17.
Punch-in/out recording
This technique is used to re-record short sections, correct mistakes, or add new sections to silent passages.
You play your part while punching in and out to start and stop the recorder. For the greatest precision, you
should use the advanced automatic punch-in/out features of the MT4X.
However, it is reasonably easy to punch-in manually. If you have a footswitch, you can also punch in and
out using your foot. This keeps your hands free for making music.
There are three basic methods for punch-in/out recording:
Using the automatic punch-in/out function.
Using the REC/PAUSE key and the PLAY key.
Using the optional footswitch.
Using the automatic punch-in/out function
With the automatic punch-in/out function, you specify the punch-in and punch-out locations. The
operation is then carried out automatically. If you make a mistake, you can repeat the operation with
precision.
1) Connect the input source, set the input select key, and adjust the GAIN control and channel fader so
that the mixer setting is identical to the previous recording.
2) Press the REC SELECT key for the track you want to punch-in.
Tip:
You should ensure that the mixer and instrument settings are identical to the original recording. If you
record a punch-in at a different volume level, for example, it will not blend into the previously-recorded track and
your edit will be obvious. You will find keeping accurate track sheets invaluable to making invisible punch-in/out
recordings. See "Tracking Sheet" on page 49.
Note:
If you are using an optional FC5 footswitch, plug it into the PUNCH I/O footswitch connector.

The REC SELECT - TRACK indicator on the display will flash.
Set the working points:
The pre-roll point - the punch-in/out operation starts playback at this point to give you a count-in.
The punch-in point - recording begins.
The punch-out point - recording ends.
The post-roll point - the punch-in/out operation stops.
3) Fast-wind or rewind the tape to the location where you want to start the pre-roll. A location two or
three measures before the punch-in point usually works well. Press the AUTO PUNCH I/O key
(
M
) to mark the pre-roll point.
Note:
You can skip step 2 at this point. However, you must select a track before you perform the actual
recording.
Note:
When you perform a punch-in/out recording, you need to find a blank section of about 1 second for your
punch-in and punch-out locations. This is because of the gap between the erase head and record/playback head.
Otherwise you may find that you have accidentally erased material that was before or after the re-recorded segment.
Note:
If you press this key while a memory point is stored (either or both memory indicators
a
on the
display are illuminated), the memory point data will be temporarily deleted and the indicator(s) switched
off. When you cancel the Auto Punch function, the memory point data will be restored and the indicator(s)
illuminated again. See "Memory Functions" on page 41.

This technique is a combination of overdubbing (see "Overdub recording" on page 15) and ping-pong
recording.
1) Connect the input source for the overdubbing channel to its corresponding MIC/LINE INPUT
connector.
2) Set the input select key to the MIC/LINE position.
3) Rotate the GAIN control to adjust the level of the input signal.
4) Use the ASSIGN keys and the PAN control to select the group bus for the destination track.
5) Set up the source tracks as listed in the previous section ("Preparation for recording" on page 29).
6) Press the REHE and PLAY keys to rehearse the overdub/ping-pong.
Play along with the tape. Adjust the channel fader, PAN controls, and equalizer controls for each
source and input channel.
7) Press the RETURN TO ZERO key to stop and rewind the tape.
8) Press the REC/PAUSE and PLAY keys to start recording. When the recording is finished, press the
RETURN TO ZERO key to stop and rewind the tape.
9) Check the recording.
Ping-pong notes
Avoid ping-pong recordings to an adjacent track (for example, avoid bouncing track 2 to track 1 or
track 3) as much as possible. Otherwise, crosstalk (the signal leak at the record/playback head) may
cause feedback.
If you must ping-pong to an adjacent track, set your recording levels carefully. Set the tape speed to
9.5 cm/sec for the highest quality sound. Do not boost the HIGH equalizer control too much. You
should also use the dbx™ noise reduction system to avoid feedback and control noise levels.
Unfortunately, sound quality will deteriorate rapidly if you overuse the ping-pong recording
technique. You should try to plan out your multitrack recording to minimize the amount of bouncing
that you need to perform. Remember, Sgt. Pepper’s Lonely Hearts Club Band by the Beatles, was recorded
on a four-track system!

Mixdown
Mixdown is the process of combining the four individual tracks into a final stereo mix. You blend
and polish the sounds before you record them onto a stereo cassette recorder or DAT recorder.
The mix is created using the various mixer controls. You adjust the track levels with the channel
faders, change the equalizations, and modify the stereo image with the pan controls. You can also
connect external signal processors, such as a reverberator or digital delay, to further refine your mix.
Connections and setup
In these instructions, the MT4X is your multitrack recorder and the stereo cassette recorder or DAT recorder
is the master recorder.
1) Using compatible cables, plug the stereo inputs of the master recorder into the STEREO OUT
connectors (g).
2) Connect any external signal processors to the MT4X. Plug a compatible cable from the AUX SEND
connector (j) into the input connector on the effect unit. Plug the output from the effect unit into
the AUX RETURN connectors (i).
For an alternative setup, you can connect an external effects unit in between the MT4X
(STEREO OUT connectors) and your master recorder.
3) Set the input select keys to the TAPE position for the individual tracks.
4) Press the MONITOR SELECT - STEREO key 0. Set the master fader to the nominal level between
“7” and “8”.
Note: If the effect unit has stereo outputs, connect it to the MT4X in stereo. Otherwise, plug it into the
L/MONO connector.
Note: The MT4X has two auxiliary (AUX SEND and AUX RETURN) channels.

10) When the recording is finished, rewind the master recorder and play back the tape.
Note: You may want to remove any count-ins before you create your master tape. There are several ways
of doing this. One method is to switch (input select key) the track that contains the count-in to the MIC/
LINE position until the count is completed and then switch it to the TAPE. Another method is to set the
MT4X to start playback after the count-in. Use the method that you find most comfortable.
Tip: You can add a synchronized MIDI part to your mix. See "Synchronized mixdown" on page 39.
Synchronization 34
User’s Guide
4 Synchronization
The MT4X has the ability to synchronize MIDI sequencers, rhythm programmers, and other devices to the
existing tracks on your tape. The following section describes some of the advanced techniques you can
employ.
When you create an overdub recording, you play along with the previously recorded tracks – matching the
tempo. This is easy for a guitarist, vocalist, or keyboard player, but not so easy for a MIDI sequencer or
rhythm machine. To synchronize MIDI instruments, you need to provide a timecode signal that the MIDI
instrument can follow. This involves recording MIDI timecode onto a track using a technique called FSK
(Frequency Shift Keying). Typically, the best time to do this is when you are laying down your basic tracks
using a MIDI sequencer or rhythm machine to set the tempo.
Some MIDI sequencers and rhythm machines are already equipped with a SYNC OUT connector. You can
plug this type of machine directly into the MT4X to record FSK onto one of the tracks.
If your MIDI sequencer or rhythm machine is not equipped with a SYNC OUT connector, you may need a
MIDI/FSK converter such as the Yamaha YMC10. You plug the MIDI/FSK converter in between your
MIDI sequencer or rhythm machine and the MT4X to record FSK onto one of the tracks.
Please refer to the user’s manual supplied with your MIDI instrument to see if it can output compatible
FSK signals.

FSK recording
Record FSK signals on track 4
The MT4X is equipped with a dbx™ noise reduction system. For recording normal audio signals, the noise
reduction system is beneficial. However, dbx™ interferes with the recording of FSK signals. This
sometimes results in an unusable sync track. Therefore, the MT4X is also equipped with a SYNC key.
When you press the SYNC key, the dbx™ system is defeated on track 4, allowing you to have noise
reduction on your audio tracks and a usable sync track.
Connections and setup
1) Connect the MIDI/FSK output from your sequencer, rhythm machine, or converter to one of the
MIC/LINE INPUT connectors.
2) Set the input select key for the corresponding channel to the MIC/LINE position.
3) Rotate the GAIN control fully counter-clockwise to the LINE setting.
4) Set the equalizer controls to the “0” (flat) position.
6) Set the channel fader to the nominal level between “7” and “8”.
7) Press the REC SELECT key for track 4.
The REC SELECT - TRACK indicator on the display will flash.
8) If dbx™ system is on, press the SYNC key (K).
The SYNC indicator (]) on the display will light.
9) If you are going to record audio signals from the MIDI instrument along with the FSK signal,
connect the audio outputs to the channel connectors and set the mixer channels. See "Initial
recording" on page 15.
Rehearsal
10) Press the REHE key to put the MT4X into rehearsal mode.
11) Start the MIDI instrument and adjust the recording levels.
Adjust the level of the FSK signals so that the level meters indicate about +6 dB.
12) Adjust the monitoring levels.
13) Stop the MIDI instrument.
Record the sync track
14) Fast-wind or rewind the tape to the beginning of your recording. Press the COUNTER RESET key to
set the tape counter to “0000”.
15) Press the REC/PAUSE and PLAY keys to start recording.
5) Press the ASSIGN
key:
and rotate the
PAN control:
fully clockwise to select the fourth (even)
group - track 4.
Note: These instructions assume you have recorded a song on your MIDI sequencer or rhythm machine that
consists of a song start, tempo, and a song end. If you programmed tempo changes, these will also be recorded on
the FSK track.

RETURN TO ZERO key to stop and rewind the tape.
Synchronized playback
Overdubbing with a synchronized performance
If your MIDI sequencer or rhythm machine cannot accept FSK signals, you may need a MIDI/FSK
converter such as the Yamaha YMC10. You need to plug the MIDI/FSK converter in between the MT4X

Synchronized mixdown
You can use the FSK signal to synchronize MIDI instruments to the previously recorded tracks on the
MT4X while you are creating a mixdown recording (see "Mixdown" on page 32).
One of the advantages of this technique is that you can add multiple instruments to your mix without
having to bounce-down tracks. To take full advantage of this technique, you may have to use an external
mixer.
Connections and setup
1) Plug a compatible cable from the TAPE OUT - SYNC/4 (k) connector into the MIDI/FSK input on
your sequencer, rhythm machine, or converter.
Set the connected MIDI instrument to receive the FSK signals from the MT4X.
2) Set any other connected MIDI instruments to MIDI clock mode to slave to the MIDI device receiving
the FSK signals. Perform any other required setup on your MIDI instruments to ensure they
perform correctly once the MT4X starts playing the FSK timecode.
Please refer to the instruction manual supplied with your MIDI instrument for further setup details.
Tip: A special feature of the MT4X is its TAPE OUT connectors. These allow you to send the track signals
directly from the recorder to your external mixer.

location of the highest level is also stored and can be displayed along with the level.
If the signal is beyond the recommended level, the maximum level segment will flash.
Confirm the maximum level
1) Press and hold the CHECK key.
2) Press the REHE key (R).
The maximum level segment of the level meters (Z) will light for as long as the two keys are
pressed. If the level is beyond the recommended level, the segment will flash.
Confirm the tape position
1) Press and hold the CHECK key.

2) Press the REC SELECT key (G) corresponding to the track you want to check.
The maximum level segment of the selected track will light and the tape counter will display the
corresponding location value for as long as the two keys are pressed. If the level is beyond the
recommended level, the segment will flash.
The following display shows Track 2 being checked.
If you reset the tape counter after the recording, the location displayed will be incorrect. Unlike the
memo function, the MT4X does not re-calculate the maximum level memory locations.
Clear the maximum level data
1) Press and hold the STOP key (W).
2) Press the CLEAR key (L).
When the data is cleared, the -20 dB segments on the level meters for all four tracks and the stereo
signal will flash three times.
Note: If the maximum level is reached a several locations, only the first location is
displayed.
Note: The maximum recording level data is NOT cleared automatically. Before each
recording, you should reset the stored levels. Otherwise you could mistake the levels of a
previous recording for the current recording.

Troubleshooting
If you experience difficulty operating the MT4X, or it does not seem to be working as it should, look up the
problem in the following table. You may find it is just a simple error, easy to correct.
Symptom Possible Cause Solution
The MT4X cannot be
powered ON.
The power cable is not correctly
connected.
Make sure the power cable is connected to a suitable
AC outlet and plugged into the AC IN connector on
the MT4X’s rear panel.
The POWER switch has not been
correctly set.
Make sure the POWER switch on MT4X’s rear panel
is pressed ON.
Note:
If the MT4X still cannot be powered ON, please contact your Yamaha dealer.
Cannot record. The REC SELECT key is not set
correctly.
Set the REC SELECT key correctly.
The setting of the ASSIGN key(s)
is incorrect.
Select the correct ASSIGN key(s) for the group and
tracks you intend to use.
The cassette is loaded incorrectly. Make sure the tape is firmly inserted in the cassette
compartment.
The cassette’s record protect tabs
have been removed.
Make sure that the cassette’s record protect tabs are
intact.
Cannot hear a connected
instrument.
The corresponding input select
key is set incorrectly.
Set the input select key to the correct position.
The fader or monitor is set
incorrectly.
Raise the fader for the input module. Make sure the
MONITOR SELECT switch is set to CUE and adjust
the CUE LEVEL control.
Recordings sound noisy or
distorted.
The recording level is set
incorrectly.
Set the channel fader so that the level occasionally
reaches +9 dB (with dbx™ ON or +3 dB with it
OFF). If the signal level is too low, the recording
may sound noisy. If it is too high, distortion may
occur.
Recordings sound dull,
suffer from wow and
flutter, or are of poor
quality.
The record/playback head and
capstan is dirty.
Clean the record/playback head and mechanism.
See "Maintenance" on page 45.
The wrong type of cassette is
being used.
Be sure to use high-quality Type II (High Bias, 70
µ
s
EQ) chrome cassettes.
The cassette tape is defective. Try a new cassette tape.
Recordings playback at
the wrong pitch.
The PITCH control was reset
during recording.
Set the PITCH control to the “0” centre-detent
position.
The tape speed was reset. Press the tape speed select key to set the MT4X back
to the correct tape speed.
Tape sync does not
function correctly.
The SYNC key was not pressed
when the dbx™ system was ON.
Press the SYNC key and connect the FSK source to
track 4.
The FSK track was recorded at too
low a level.
Re-record the FSK signal. Make sure the recording
level is set to about +3dB.
The MIDI-to-FSK converter is
incorrectly connected.
Make sure the connections are correct.

Maintenance
The MT4X requires regular maintenance to remain in top operating condition. If you observe the following
problems, you should clean and possibly demagnetize the unit:
A drop in level at high frequencies.
An increase in wow and flutter.
Fluctuating sound or signal dropout.
Excessive noise.
Cleaning the recording head and
components
The record/playback head is in constant contact with
the recording tape. Over time it will become coated
with an oxide residue and need to be cleaned. The
other components — the capstan and pinchroller —
also tend to become coated with residue and dust
particles.
Pinchroller
Record/playback head
Erase head
Capstan
Clean the Shaded Areas
To clean the record/playback head and capstan, use a head-cleaning kit. These kits generally include
specially-made cotton swabs and an isopropyl alcohol-based cleaning solution, and are available at audio
and electronics shops. Follow the directions on the kit, carefully wiping the record/playback head and the
capstan with a swab soaked in cleaning solution. It is best to clean the pinchroller with a non-alcohol based
rubber cleaning solution, which is often included in the cleaning kits. Alcohol tends to dry out and corrode
the rubber part of the roller.
You should clean the record/playback head and capstan after every 10 hours of use.
Demagnetizing the recording head
As the recording tape passes over the record/playback head, it tends to impart a tiny amount of
magnetism to the head. The head collects this magnetism over a period of time, slowly becoming
magnetized. You need to demagnetize the head using a commercially-available head demagnetizer. These
are also available at most audio and electronics shops.
You should demagnetize the record/playback head after every 20 to 30 hours of use.
Note:
Read the directions on the demagnetizer carefully. If you do not use the demagnetizer correctly, you could
seriously damage the record/playback head. Also, keep recorded tapes away from the demagnetizer when it is in use;
the demagnetizer can accidentally erase your tapes.

Glossary
Auxiliary Bus
The MT4X has two auxiliary buses. These buses are generally used to send signals to external signal
processing units.
Auxiliary Send — Each channel module includes an AUX control, which selects an auxiliary bus
and determines the amount of signal fed to corresponding the AUX SEND output connector.
Auxiliary Return — The AUX RETURN controls determine the destination and amount of signal
that is fed back into the MT4X via the AUX RETURN input connectors. You can return an effect in
stereo, to further enhance your recording.
Capstan
A slender metal pillar adjacent to the pinchroller. The capstan is driven by the DC servo motor and
controls the tape speed. The tape pulled across the erase and record/playback heads by the pressure
between the capstan and pinchroller.
CUE monitor
This bus is used to listen to previously recorded tracks. It is mostly used to assist the musicians
recording a new part. You can also process effects through the monitor bus without recording them
to tape. The CUE bus is monaural.
DAT (Digital Audio Tape)
A two-channel, 16-bit digital recording system using magnetic tape and a rotary head mechanism.
DAT machines are often used as master recording units. Professional units can record at 33 kHz,
44.1 kHz, and 48 kHz sampling rates.
dbx™ noise reduction
A system to reduce tape noise and improve the dynamic range of analog tape. dbx™ employs a pre-
emphasis to boost the high frequencies, followed by a 2:1 compression of the signal during

recording. The signal is expanded and then de-emphasized on playback. The MT4X uses dbx™
noise reduction to reduce noise and keep your recordings clean and crisp.
Demagnetizer
A hand-held device that removes the residual magnetic field that routinely builds up on a recording
head. Without demagnetizing (also called degaussing), this residual magnetic field can cause
distortion. Use of a demagnetizer is an integral part of maintaining any tape recorder.
Equalization (EQ)
The process of adjusting (boosting or cutting) the frequency ranges for optimal sound. Many
engineers try to record with flat equalization, only adjusting the frequencies on mixdown.
Fader
Each channel module contains a fader, a slider that is used to adjust the level of that channel relative
to the other channels. The MASTER module fader is used to adjust the overall stereo level.
FSK (Frequency Shift Keying)
A method of recording MIDI clock data onto one of the tracks of the MT4X. A device translates the
data into two distinct frequencies that represent the two binary states: “on” and “off”. Some MIDI
instruments can directly output FSK sync signals. Otherwise, you will need a MIDI/FSK converter
such as the Yamaha YMC10.
GAIN
Various musical instruments and devices output different levels of signal. Gain is a measure of
electronic input over output. Each channel module includes a GAIN control that can alter the input
levels to compensate for line, instrument, or microphone levels.
Head
A transducer used to convert electrical impulses into patterns of magnetism during recording and
to convert patterns of magnetism into electrical impulses during playback. The MT4X uses a special
4-track permalloy record/playback head.
Instrument level
The level of gain output by such devices as an electric bass or guitar.
Line level
The level of gain output by such devices as a synthesizer, drum machine, CD player, etc.
Master recorder
A second tape recorder used during the mixdown process. The master recorder can be any two-
track stereo recorder, such as a stereo cassette, reel-to-reel, or DAT recorder.
MIC/LINE input
Each channel module includes a MIC/LINE input to connect a microphone, musical instrument, or
electronic device for recording.
MIDI (Musical Instrument Digital Interface)
A digital data format standardized to ensure communication compatibility between electronic
musical instruments from different manufacturers. MIDI allows you to control multiple instruments
from one keyboard.
Mixdown
Usually the final process in a multitrack recording where you combine the previously recorded
tracks (often four), plus any effects or signal processing, into a stereo mix.
Module
The MT4X includes four channel modules. Each module consists of an input section (input select
key and GAIN control), an equalization section (HIGH, MID, and LOW controls), an auxiliary
section, a routing section (ASSIGN keys and PAN control), and a fader.

MONITOR/PHONES control
Controls the amount of signal fed to the speakers through the left and right MONITOR OUT jacks
or to the stereo PHONES (headphone) jack.
Multitrack
A tape recorder with more than two tracks. The MT4X is a four-track machine. Each track can be
independently recorded at an optimum level, and then mixed, equalized, processed, and panned
into a final mixdown.
Overdub recording
Recording one track while listening to another track or tracks. The process of overdubbing can also
be implemented by a synthesizer synchronized to a sync track. See Synchronization.
Pan
A control that sets the relative position of a sound in a stereo image. Each channel module includes
a PAN control. The PAN control is also used for track group assignment.
Pinchroller
A small rubber wheel which presses the tape against the capstan.
Ping-Pong recording
Also known as bouncing. The transfer of recordings from several tracks to one other track
effectively increase the number of tracks available for recording.
Pitch
The frequency of a musical sound — its relative highness or lowness compared to other notes. The
PITCH control changes the pitch of a playback by fine-tuning the speed at which the tape passes
over the head.
Post-fader
MT4X’s auxiliary sends are configured post fader, which means that the send signal is sourced after
the fader. To feed a signal to an external effects processor via the auxiliary send, turn up the AUX
control and raise the fader. The advantage is that you can fade both channel and auxiliary send
signals simultaneously. Compare with Pre-fader.
Pre-fader
A signal that is sourced before the fader, therefore, the fader has no control on the signal.
Punch-In/Out recording
A recording technique used primarily to correct mistakes by re-recording over a short section of a
track.
Stereo mix
A two-track mix with left and right stereo channels. The finished product of a mixdown session.
Striping the tape
Applying a timecode to the tape for synchronization purposes. On the MT4X, you apply the
timecode to Track 4.
Synchronization
The technique of coordinating external MIDI instruments and the playback of the MT4X via a
timecode. See Overdub recording.
Track
A physical band on a recording tape created by a recording head. The MT4X creates four tracks on
one side of a standard audio cassette.
Tracking sheet
A chart that lists what was recorded on each track, the settings used, and in what order.
