1. SYSTEM POWER INDICATORS

When  Power  switch  is  on,  AC  or  DC  LED  will  illuminate  depending  on  input  Power  source.  When  Power
switch is off, STBY LED will illuminte.

NOTE: During operation of DC, amplifier is keep going to work even if the switch of power is turned off.

2. SIGNAL INDICATORS (CH1, CH2, CH3, CH4[DPA-300Q/QO ONLY])

The LEDS indicate the amplifier’s output signal levels. 
SIG : Green, -10dB : Green, Clip : Yellow, PROTECT : Red

3. VOLUME CONTROL (CH1, CH2, CH3, CH4[DPA-300Q/QO ONLY])

Turn the volume controls clockwise to increase gain and counterclockwise to decrease gain.

4. COOLING VENTS

Air flow is front to back. DO NOT block front or rear air vents.
