MA2120 Setup Guide
Setup Mode (Advanced settings)
Advanced settings for MA2120 power amplifier can be configured by using the [SETUP] encoder and input level knobs 1 - 8.
There are three types of setup modes that can be used to configure advanced settings. Operation and functionality for each setup mode
type is shown as follows:
• Input channel setup mode  Press and hold the [SETUP] encoder for at least one second.
Microphone high-pass filter, microphone compressor, input EQ (TREBLE, BASS), reverb, ducker, leveler
• Output zone setup mode  Press and hold the [SETUP] encoder and input level knob 1 simultaneously for at least one
second.
Chime volume, linked operation of [SPEAKERS] and [LINE OUT]
• Other setup mode  Press and hold the [SETUP] encoder and input level knob 2 simultaneously for at least one second.
Feedback suppressor, DCP setup
Advanced settings can be configured with the following procedure:
Once each operation is carried out successfully, the corresponding indicator flashes three times at high speed.
When selecting functions or channels, the indicator flashes slowly to indicate which functions or channels are able to be selected.
While adjusting a parameter, you can press an input level knob so that the corresponding [INPUT SIG] indicator (showing the selected
function) and [INPUT PEAK] indicator (showing the selected channel) both flash.
After you set the parameter, press the [SETUP] encoder to confirm the setting.
At this time, press and hold the [SETUP] encoder for at least four seconds to reset the current parameter to the default setting.
Once the parameter has been confirmed, the device mode returns to the channel selection. Press the [SETUP] encoder again to return
to the function selection, and once more to return to the regular mode.
In setup mode, the current settings are indicated by the three indicators above the [SETUP] encoder.
The indicators can turn on or flash to show the on/off state or the currently set value. In addition, depending on the parameter value, the
flashing behavior may differ. For example, when the delay time of echo set is increased, the lighting time during flashing becomes longer.
In this guide, the behavior of the indicators is shown as follows.
: Lights continuously
: Flashes
: Off
