(Connection to the [REMOTE] connector) 1 Terminal screw Loosen Slotted screwdriver 2 Approx. 5 mm (approx. 0.2") 3 Tighten 4 Euroblock plug NOTE • You must use the supplied Euroblock plugs. If the plugs have been lost, please contact your Yamaha dealer. • Use the 6-pin Euroblock plugs when connecting to the [INPUT] connectors 1-6. • To prepare the cable for attachment to a Euroblock connector, strip the wire as shown in the illustration using stranded wire to make connections. With a Euroblock connection, stranded wires may be prone to breakage because of metal fatigue due to the weight of the cable or due to vibration. When rack mounting your device, use a lacing bar when possible to bundle and fasten the cables. • Do not tin (solder) the exposed end. 1 2 3 4 Loosen terminal screws. Insert cables. Securely tighten terminal screws. Insert the Euroblock plug into a terminal of this device. Connecting Speaker Cables The [SPEAKERS] output connectors on the rear panel are barrier strip type connectors. The connections are described below for two methods: using a spade lug and using a bare conductor. Caution • Ensure that load is not applied to the speaker cable. • This device uses a BTL (Balanced Transformer-Less) connection method for the amplifier output. As the amplifier output is sent to the positive and negative connectors, any contact with other terminals or the device chassis may lead to malfunction. NOTE Connect the cables so that the amplifier’s “+” and “-” symbols match those of the speaker. If they are reversed, the phase will be reversed and the sound will not be output correctly. When using a spade lug When using a bare conductor Loosen the screw, insert the spade lug all the way from below, and tighten the screw. Loosen the screw, wrap the conductor wire around the barrier strip terminal, and tighten the screw. Be sure that the bare wire does not touch the chassis. Speaker cable Wire should not touch the chassis. ≥3.2mm (≥ 0.13") ≥5.8mm (≥0.23") 15mm* (0.6") * Actual size MA2120 Setup Guide 3  Connections Connecting Microphones or External Devices Connect a microphone, BGM tuner, CD player or other portable audio player to an [INPUT] connector/jack using an appropriate cable when the device is powered off. After finishing all connections, connect the power cord to an AC outlet. Warning When connecting the power cord to an AC outlet, an input signal will turn on the power of this device by the auto-wake function. To avoid unexpected loud sounds, be sure to connect microphones and external devices with the power off status. RCA Euroblock MA2120 rear panel NOTE Refer to “Attaching Euroblock Plugs” for Euroblock plug installation. „ Connecting Microphones „ Using the Mono Sum Input Connect microphones to [INPUT] connectors 1 - 6 using a Euroblock plug. When using a microphone that requires phantom power (+24V), set the [GAIN] switch to “MIC(+24V)”. For microphones that do not require phantom power, set the [GAIN] switch to “MIC”. [INPUT 5] and [INPUT 6] are equipped with mono sum input. Each can be used for summing a line level stereo source, or two separate mono sources. The input signal is mixed directly to mono and output to the zone that was selected using the [ROUTE] switch for [INPUT] jack 5 and 6. Use of the [MONO SUM INPUT] jacks can allow a large number of external devices to be connected without the need for a separate mixer. However, note that when there is also input via Euroblock plugs for [INPUT] connector 5 or 6, the signal input from [MONO SUM INPUT] is mixed in with the signal from [INPUT] connector 5 or 6. Caution • Only switch the phantom power on/off when the [VOLUME A] and [VOLUME B] knobs are turned all the way down. • Keep the phantom power turned off when it is not required, or if you wish to connect a non-supporting device. • Do not connect or disconnect the cable while phantom power is left on. „ Connecting External Devices Use the following procedure to connect a line level external device. Use a Euroblock plug to connect via [INPUT] connectors 1 - 6. At this time, set the [GAIN] switch to “LINE”. If the external device has an extremely low output level, set the [GAIN] switch to “MIC” to improve the input gain. Use an RCA cable to connect to [INPUT] jacks 7 and 8. If the source is stereo and you are using zone A and zone B as stereo, set the [MODE] switch to “STEREO”. If you are using zone A and zone B separate from each other, set the [MODE] switch to “MONO” and use the [ROUTE] switch to select which zone receives the audio output. Use a mini-stereo plug to connect via the [AUX IN] jack on the front panel. The signal from the [AUX IN] jack is mixed into the same signal path as [INPUT] jack 8. 4 MA2120 Setup Guide  Connections Connecting the PA2120 Power Amplifier When using a large number of speakers that the MA2120 is not capable of handling alone, it is possible to connect a PA2120 power amplifier to provide extra capacity. To utilize this functionality, connect the [LINE OUT] jack of the MA2120 to the [INPUT] jack of the PA2120 using an RCA cable when all devices are powered off. If you wish to further expand capacity, it is possible to connect another PA2120 power amplifier. Simply connect the [THRU OUT] jacks of the PA2120 to the [INPUT] jacks of the additional PA2120 power amplifier. After finishing all connections, connect the power cord to an AC outlet. Warning When connecting the power cord to an AC outlet, an input signal will turn on the power of this device by the auto-wake function. To avoid unexpected loud sounds, be sure to connect microphones and external devices with the power off status. NOTE When lowering the output level with the [VOLUME] knobs or an external control panel, the Auto-wake function of PA2120 may not work properly because of an absence of input level. Be sure to set the output level to the PA2120 enough for the Auto-wake function to work properly. MA2120 rear panel PA2120 rear panel Further expanding PA2120 rear panel In setup mode, you can set whether the output level from the MA2120 [LINE OUT] jacks is linked with the output level from the MA2120 [SPEAKERS] terminals, or independently controlled. Set the [VOLUME] knobs of the PA2120 to maximum to adjust the level of PA2120 to the same level of MA2120. Linked operation when using the control panel can be set using the [SETUP] DIP switch. MA2120 Setup Guide 5  Connections Connecting a Control Panel Connecting Yamaha Digital Control Panel (DCP1V4S, DCP4S, DCP4V4S) to MA2120 enables you to control the volume, to switch inputs, etc. remotely. You can connect up to two control panels. The total length of the cables from the MA2120 to the last control panel must not exceed 800 meters in the case of 24AWG. NOTE When connecting control panels via DCH8, the total length of the cables to the final control panel must be less than 200m (according to DCH8 specifications). If you need a longer connection, we recommend not using the DCH8, but connecting the devices in a daisy-chain configuration. Precautions when connecting two control panels: • Connect them in a daisy-chain configuration. • Set the panel IDs separately. • Set the second control panel DIP switch 4 to ON. (termination setting) This setting is only for the second device when connecting two devices. • Ensure that the total Ethernet cable length does not exceed 800 meters in the case of 24AWG.

Linked operation of output levels from [SPEAKERS] terminals and [LINE OUT] jacks Set the [SETUP] DIP switch on the rear panel to [SPEAKERS+LINE OUT] to allow the output level of the [SPEAKERS] and [LINE OUT] to be controlled together via the control panel. Input Signal On/Off Switching and Linked Operation The input channel of a device such as a microphone can be switched on and off by using the switch on the control panel. It is also possible to link on/off operation so that it triggers a chime, or mutes the input signal from [INPUT] jacks 7 and 8. 6 MA2120 Setup Guide  Connections Using the [REMOTE] Connector (Euroblock 3-pin) You can connect switches to the rear panel [REMOTE] connector, and use them to remotely mute/unmute outputs of all channels, or switch the power standby/on status. From the left, the [REMOTE] connector consists of M (mute all), S (standby), and G (ground) pins. The [REMOTE] connector uses a Euroblock plug. For details on how to connect Euroblock plugs, refer to “Attaching Euroblock Plugs.” Muting/unmuting all channels Turning mute on Turning mute off Switching the power standby/on status Switching the power to standby Turning the power on NOTE • When the device is put into standby mode via the [REMOTE] connector, it is not possible to turn the power back on by pressing the [z] button on the front panel, or by the auto-wake function with input signal detection. The power can only be turned on via the [REMOTE] connector. • When the device is put into mute mode via the [REMOTE] connector, the [z] button will flash in green.

This allows the speaker system to be effectively driven with much lower current than is required for a low-impedance connection. Therefore, a large number of speaker systems can be connected. Even over long distances, there is very little transmission loss due to the cable resistance being negligible in relation to the impedance of the speaker system. High-impedance speaker connections usually operate at a specific maximum power amplifier voltage of 100 or 70 volts. The more orthodox low-impedance connection does not use a speaker transformer. The speaker systems are directly connected to the power amplifier with a rated impedance generally around 4 - 16 ohms. For short distances over which cable resistance is insignificant, low-impedance connections deliver a sound quality that is superior to high-impedance connections. The differences between connection methods are explained as follows. „ Multiple Speaker System Drive Capability High-Impedance Connections As long as the total nominal power input rating for all speakers is within the power output capability of the amplifier, any number of speaker systems can be connected in parallel. The power input rating is determined by the speaker systems and speaker transformers used. It is also possible to connect speaker systems that have different input power ratings. In the case of speaker systems that are capable of changing their input power rating (Yamaha VXC and VXS series, etc.), this can be utilized to vary the volume of each speaker. Speaker transformer 70V/100V 10W 10W 10W 10W 10W Low-Impedance Connections When connecting multiple low-impedance speaker systems to a single channel, the following methods are possible. Parallel Connection When multiple speaker systems having the same impedance are connected in parallel, the total impedance becomes the individual speaker system impedance divided by the number of systems connected. 4Ω Cannot be connected 8Ω 8Ω 8Ω Total impedance = 4Ω Serial Connection When connected in series, the total impedance is simply the sum of the impedances of the speaker systems connected. However, if one speaker system happens to fail, the electrical signal will not be passed on and subsequent speaker systems will be affected. 4Ω Interruption 18 MA2120 Setup Guide 4Ω Failure No sound Total impedance = 8Ω  Technical Specifications Specification Outputs （SPEAKER OUT) Output Power 20msec Burst (THD+N=1%) AMP MODE = 3Ω 100W x 2ch AMP MODE = 4Ω 120W x 2ch AMP MODE = 8Ω 100W x 2ch AMP MODE = 70V/120W 120W x 2ch AMP MODE = 100V/120W 120W x 2ch AMP MODE = 70V/200W 200W x 1ch AMP MODE = 100V/200W Terminal 200W x 1ch 7.62mm BARRIER STRIP 4pin Outputs (LINE OUT) LINE OUT Actual source impedance For use with nominal Output Level Nominal Terminal 600Ω 10kΩ Lines -10dBV (316mV) MONO RCA PIN x2, unbalanced Inputs MIC IN (INPUT 1-6) Input Level INPUT 1-6, Euro, balanced Sensitivity -56dBu (1.23mV) Nominal -36dBu (12.3mV) Max before clip -8dBu (0.309V) LINE IN (INPUT 1-8) Input Level INPUT 1-6, Euro, balanced Input Level INPUT 5-8, RCA, unbalanced Input Level INPUT 8, ST mini phone, unbalanced Sensitivity -24dBu (48.9mV) Nominal -4dBu (0.489V) Max before clip +24dBu (12.3V) Sensitivity -30dBV (31.6mV) Nominal -10dBV (316mV) Max before clip +10dBV (3.16V) Sensitivity -30dBV (31.6mV) Nominal -10dBV (316mV) Max before clip +10dBV (3.16V) Terminal MIC/LINE IN INPUT 1-6 3.5mm Euro Block 6pin x3 balanced LINE IN INPUT 5-6 MONO RCA PIN x4 unbalanced INPUT 7-8 STEREO RCA PIN x2 unbalanced INPUT 8 (Front Panel) 3.5mm STEREO mini phone x1 unbalanced MA2120 Setup Guide 163  Technical Specifications Electrical Characteristics Class D Amplifier type (Output circuitry) THD+N Frequency Response LINE IN to SPEAKER OUT, Half power@1kHz AMP MODE = 3Ω, 4Ω, 8Ω ≤ 0.2% LINE IN to SPEAKER OUT, Half power@1kHz AMP MODE = 70V, 100V/120W ≤ 0.2% LINE IN to SPEAKER OUT, Half power@1kHz AMP MODE = 70V, 100V/200W ≤ 0.2% LINE IN to SPEAKER OUT, 50Hz to 20kHz@1W AMP MODE = 3Ω, 4Ω, 8Ω 0dB, -3.0dB, +1.0dB LINE IN to SPEAKER OUT, 90Hz to 20kHz@1W AMP MODE = 70V, 100V/120W 0dB, -3.0dB, +1.0dB LINE IN to SPEAKER OUT, 90Hz to 20kHz@1W AMP MODE = 70V, 100V/200W 0dB, -3.0dB, +1.0dB LINE IN to LINE OUT, 20Hz-20kHz 0dB, -2.5dB, +1.0dB Crosstalk MIC/LINE IN to other MIC/LINE IN Load Protection POWER/STANDBY SW on/off Output Voltage Protection Amplifier Protection Power Supply shutdown Thermal Limit output → Mute → Shutdown Mute the output (with automatic restoration) Integrated Power Limit Thermal Connectors Power supply shutdown Over current Limit power → Power supply shutdown Conventional cooling, bottom to up airflow Front Panel POWER/STANDBY SW, INPUT volume x 8, SETUP encoder x 1 OUTPUT volume x 2, BASS EQ volume x 2, TREBLE EQ volume x 2 Rear Panel SETUP DIP SW x1, SPEAKER A/B DIP SW x2, ROUTE SW x4, GAIN SW x3, MODE SW x1 Analog In (MIC/LINE) Analog In (LINE) Analog Out Speakers Remote Indicators AC Power Requirement 164 MA2120 Setup Guide Compress output Power supply shutdown Over voltage Cooling Controls Compress output voltage when needed DC-fault Over current Power Supply Protection ≤ -70dB Mute the output 3.5mm Euro Block 6pin x3 (Rear) MONO RCA PIN x4 (Rear), STEREO RCA PIN x2 (Rear), 3.5mm STEREO mini phone x1 (Front) MONO RCA PIN x2 (Rear/LINE OUT) 7.62mm BARRIER STRIP 4pin x1 (Rear) RJ45 x1 (Rear/DCP), 3.5mm Euro Block 3pin x1 (Rear/REMOTE) POWER x1 (Green/Orange), INPUT SIGNAL x8 (Green), INPUT PEAK x8 (Red), SETUP x3 (Green), OUTPUT SIGNAL x2 (Green), OUTPUT LIMIT x2 (Red) 100V, 120V, 230V-240V 50Hz/60Hz (*1) *1 It has confirmed that it is working with ±10% of the voltage of the rated supply voltage.  Technical Specifications Power Consumption Standby, default setting AMP MODE = All ≤ 1W Idle AMP MODE = 3Ω, 4Ω, 8Ω 15W Idle AMP MODE = 70V, 100V 20W 1/8 Output, Pink noise AMP MODE = 4Ω 60W 1/8 Output, Pink noise AMP MODE = 70V/120W 60W ENERGY STAR • It automatically enters into standby mode when no input signal is detected for 25 minutes in order to save power while not in use. • Amplifier efficiency: 44% and more. • Less than 1W in standby.
