1. Power LED

This LED illuminates when the AC Mains are plugged in.
Input 1
2. Limit LED Indicator
Balanced Input
The LIMIT LED will illuminate when the MA40G/MA60G is in a clipping condition, caused by excessively high input levels
or a GAIN control is turned up too high. An occasional flash is OK. Check that the proper signal level is being fed into the
inputs and/or turn the input gain down until the LED is no longer illuminated. Refer to Limit LED & Load Conditions for
more information.
3. Signal LED
When the signal LED illuminates, this indicates that input signals connected to the amplifier are capable of
driving the MA40G/MA60G to full power.
