Indicator LEDs:
-
Protect:
Lights red if the amplifier has short-circuited or overheated, which will be muted
automatically. Upon reaching normal operating conditions, the device reverts to normal operating
mode after a few seconds.
-

Lights red when the limiter starts working. If the limiter LED lights up permanently or for
longer periods, the gain level should be reduced. Failure to do so may result in a distorted sound.
-
Signal:
Lights green as soon as an audio signal is present. The input signal monitoring is performed
before the Main Level controller.
-
Power:
Lights green once the system is properly connected to the mains power and switched on.
