Q PROTECTION
Indicator
The PROTECTION
indicator
lights for approxi-
mately 6 seconds after the POWER switch is pressed
to indicate that the protection circuitry is operating.
No sound is output from the speakers while this
indicator is lit.
This indicator will also light and
sound will be cut off to the speakers if the protec-
tion circuitry is activated at any other time during
amplifier operation due to factors such as overheat-
ing or the detection of excessive DC voltage at the
outputs. When the problem is corrected, the protec-
tion circuitry is automatically deactivated, the indi-
cator goes out, and the amplifier resumes normal
operation.
SIGNAL Indicators
The SIGNAL indicators light when the output level
(output voltage at the speaker terminals) exceeds 2
Vrms.
This is equivalent to 1/2 watt with an 8 ohm
load or 1 watt with a 4 ohm load.
A lit SIGNAL
indicator indicates that some type of signal is being
input to that channel.
CLIP Indicators
The CLIP indicators light if the output distortion
exceeds approximately 190. These indicators, which
are independently provided for each channel, indi-
cate that an excessively large input signal is being
applied to the amplifier causing clipping to occur.

© Input Attenuators
The input attenuators аге 31-position click-stop con-
trols used for adjusting input sensitivity.
Rotating
fully in the clockwise direction sets the attenuator at
0 dB, while rotating fully in the counterclockwise
direction provides infinite attenuation.
POWER
Switch & Indicator
Pressing this switch turns the power ON, and press-
ing again turns the power OFF.
The indicator lights
when the power is ON.
Knob Locks (supplied)
Push these locks over the attenuation controls to
prevent accidental resetting of the levels. Pull them
off again if you need to reset the levels.
