1. POWER SWITCH
To turn the unit ON or OFF, press the upper or lower 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 illuminates when the power is turned “ON”.
3. SUBWOOFER LEVEL CONTROL
This controls the level of the signal for the Subwoofer channel.
The actual voltage gain is shown in dB. Turn the level down
(counterclockwise) if the Clipping LEDs (6) illuminate steadily
(indicating too strong an output signal).
4. CHANNEL 1 & 2 LEVEL CONTROLS
These control the level of channel 1 & 2.
5. SIGNAL LED INDICATORS
These LEDs illuminate to confirm the presence of an input
signal greater than 110mV on that channel of the amplifier.

6. CLIP (PEAK) LED INDICATORS
These LEDs illuminate if the corresponding channel’s output is
within 3dB of clipping. Occasional blinking of the LEDs is
acceptable, but if they remain on more than intermittently you
should turn down either the power amplifier’s level controls or
reduce the output level of the preceding component to avoid
audible distortion.
[Caution: Prolonged use at levels in excess of clipping can
cause damage to your speakers and even the internal amplifier.
Carefully monitor the clipping LEDs to avoid prolonged clipping.]
7. PROTECT LED INDICATORS
These LEDs illuminate if the power amplifier’s safety circuit has
been triggered to shut off the outputs. This can occur if the
output connection has been shorted, the load impedance is too
low, there is DC voltage at the outputs, or if the power amp
overheats due to excessive clipping. When either of these LEDs
is lit up, turn OFF the power and check the output connections
to verify that they are correct. If the output connections are
shorted, or a speaker is blown, correct the problem (or unplug
the speaker) and try turning the amp back on. It’s also prudent
to carefully feel if the amplifier is very hot due to excessive
clipping. If so, allow the amp to cool down before turning the
power back on.
