1. Power Switch -
This switch controls the units main power.
This is used
to activate the channels built-in limiter. The limiter reduces the average
output level when the signal begins to distort, this process is designed
to reduce distortion and protect the speakers. See limiter page 13.
3. Channel 1 Clip Indicator -
This red LED will begin to f lash when
channel one begins to overload (clip). At this point channel one will be-
gin to distort. Under heavy clipping activity lower the channel one gain

These vents are used for proper cooling. Never
block these vents and keep them clean at all times.
10. Channel 1 Gain Control -
This rotary knob is used to control the
output signal of channel one. Turning the knob in a clockwise direction
will increase signal output.
11. Channel 1 Signal Indicators -
These green and yellow LED’s will
glow according to the average signal output.
12. Channel 2 Signal Indicators -
These green and yellow LED’s will
glow according to the average signal output.
13. Channel 2 Gain Control -
