Connecting The Pa2120 Power Amplifier - Yamaha MA2120 Setup Manual

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.

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.
