CAM160 / CAM80 – 7
19. Auxiliary Inputs 1 and 
Unbalanced, auxiliary signals enter the amplifier via 2 pairs
of RCA connectors. Attenuation is controlled by the AUX
potentiometer on the front panel of the amplifier.
Select either Aux 1 or Aux 2 using the front panel selector
switch (item 2 on page 4). The selected Aux input is routed
to the mixing section of the amplifier.
0. Processing Loop
External processing is possible by using the Pre-out/Amp-in
processing loop. The PRE-OUT RCA connector is pre-
amplifier, and represents the same mix as the amplified
output, adjustable by the EQ and the Volume controls. The
amplifier ships with a high quality “U” jumper installed.
To connect an external mono processor, first pull out the
"U" jumper, and connect the PRE-OUT to the input of your
external processor. Connect the output of your external
processor to the MAIN IN. Use high quality RCA patch
cords, as short as possible to do the job.
There will be no output if the U jumper is missing, so check
this as a troubleshooting measure.
1. Tape Outputs and Gain
The Tape-out output can be used to drive an external
recording device. The signal exiting this stacked RCA pair
is the same as the audio mix, pre-master volume control,
and can be used to drive a second amplifier at line level.
It’s output level is controlled by a potentiometer just above
the RCA jacks.
. Chime Level Control
This potentiometer controls the chime level when it is
actuated (via contact closure at the chime barrier strip).
Adjusting the potentiometer effects the chime level passed
on to the amplifier section. It has a range of ± 10 dB.
3. Low Cut Filter
Press this button in to engage the low-cut filter on the
output of the amplifier. It is fixed at 100 Hz with a 12 dB
slope per octave, and it serves to minimize transformer
saturation in constant voltage systems. Frequencies below
100 Hz are attenuated at a rate of 12 dB per octave.
4. Priority Depth Level
When a priority signal is detected, this potentiometer
controls the depth (attenuation) of signals that are being
“ducked.” In the fully CW position, no attenuation will
occur. In the fully CCW position, all signals that are not a
priority signal are completly muted.
5. External Volume Control
This terminal is provided for remote volume control. If you
connect a (user-supplied linear-taper 10K pot), you can
remotely control the volume of the amplifier in the same
way that the front panel volume control does.
6. Fault Relay
If a fault is detected in the amplifier section, the positive
terminal of this external connector is energized. This
external connector can be used to connect to an external
device to initiate a “fault” action as dictated by the user.
Additionally, the “fault” LED on the front of the amplifier
will light.
