Front Panel 

1. Power Indicator 

This LED illuminates when the AC Mains is plugged in.

2. Limit Indicator

The LIMIT LED will illuminate when the PA40G/PA60G 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 Indicator 

When the signal LED illuminates, this indicates that input signals connected to the amplifier are capable of driving the PA40G/PA60G to 
full power.

4. Input 1 Gain 

Input 1 level control potentiometer varies the amplitude of the signal fed into the amplifier. Turn clockwise to increase and  
counter-clockwise to decrease the signal level.
