playing), one channel at a time, adjust the TRIM control so the PEAK LED flashes. 

Once the TRIM is adjusted, bring up each channel LEVEL control to a comfortable 

level being careful not to set levels too high, causing feedback. Repeat these steps for 

all input channels. 

Make any necessary adjustments for monitor sends and master, effects sends and 

returns, and equalization settings as needed.

Located on the rear of the mixer, this switch turns the power on 

and off. The POWER LED (#13), on the front of the mixer, will illuminate when the power is on.

Two 

 and two Speakon-type connectors are provided for 

connection of the output of the amplifier to speakers. These outputs are rated for speaker connections 

of 4 to 8 ohms. Do not connect a speaker load of less than 4 ohms (each) to these outputs or it could 

result in damage to the amplifier.

This fan provides cooling to the internal amplifier. To prevent overheating, do not 

obstruct airflow to the back of the mixer.
