Input Volume Controls and Signal / Clip Indicator
Each input module may be individually controlled by its corresponding
volume control knob. A single LED located above each channel’s volume
control indicates the audio activity of that channel’s input. Green indi-
cates signal present at the input. Red indicates that the input signal com-
ing from the input module into the mixer is clipping and distorted. This
is caused by either an input signal that is too high or an input module
volume control (gain) that is set too high.
Bass and Treble Controls
The treble control has a cut/boost range of +/-
1
0 dB at frequencies
above
1
0 kHz and provides a roll off after 20 kHz to reduce gain above
the audio range. The bass control has a cut/boost range of +/-
1
0 dB at
frequencies below
1
00 Hz.
Master Volume Control
The overall volume level of the mixer is set by a Master Volume control.
The Master Volume control is motorized and can be controlled by man-
ually adjusting the knob or by a remotely-mounted control
station. Connections and requirements for the remote control station
are described in the
Connections
section, under
Remote Volume Control
.
Average/Peak Switch & LED Output Meter
The LED Output Meter is an
11
-segment meter that registers either the
average or the peak level of the mixer’s output signal. The meter can be
set to read either the average output signal (button in) or the peak
ouput signal levels (button out) by using the Avg/Peak button at the
bottom of the meter.
Power Switch / Power Indicator
The AC power to the amplifier is controlled by the Power rocker switch.
A red LED indicator lights to confirm the power on status of the mixer.
