1. POWER SWITCH
To turn the unit ON or OFF, press the left or right portion
of this button. Before turning on the amplifier, check all
connections and turn down the level controls. A
momentary muting is normal when turning the amplifier
on or off. (Caution: Always turn on your power amplifier
last, after all your other connected equipment, and
always turn off your power amplifier before your other
connected equipment.)

2. POWER LED INDICATOR
This LED flashes and then illuminates when the power is
turned “ON”.

3. CLIP (PEAK) LED INDICATORS
These LEDs illuminate if any section of the power
amplifier’s output are within 3dB of clipping. Occasional
blinking of the LEDs are acceptable, but if they remain on
more than occasionally you should turn down either the
These LEDs illuminate if any section of the power
amplifier’s output are within 3dB of clipping. Occasional
blinking of the LEDs are acceptable, but if they remain on
more than occasionally you should turn down either the
power amplifier’s level controls or reduce the output level
of the preceding component to avoid audible distortion or
hard clipping. (Note: Operating the amplifier at hard
clipping can result in overheating or may damage your
amplifier over a period of time. Amplifiers that are
damaged due to such user neglect, or improper
operation, are not covered under warranty.)

4. SIGNAL LED INDICATORS
These LEDs illuminate to confirm the presence of an
input signal greater than 100 mV at that channel of the
amplifier

5. LEVEL CONTROLS
These control the level of signal coming into each
channel. The actual voltage gain of the amplifier is
shown in dB. Turn these controls counterclockwise if the
peak LEDs illuminate steadily (indicating too strong an
input signal).
