The activation of the amplifiers is controlled by the 'Auto on' potentiometer.
Each amplifier actives by themselves when an analog audio signal is present at its
input. The threshold to activate the amplifier can be set with the potentiometer
between 7 mV to 300 mV.

Description Remark
Remote on Activate with inputs of the 'control' connector pins 9-10 or 11-12
Auto on Activates when signal is present
Always on Amplifier is always active
