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.

Functions Operated Via the Control Panel

Several useful features of the MA2120 power amplifier can be utilized by connecting a control panel.
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.
