CAM160 / CAM80 – 3. FRONT PANEL FEATURES
1. INPUT LEVEL
5. MASTER VOLUME
These controls allow you to individually adjust the volume
level of each input. We recommend that you turn down the
level controls of any unused or little-used inputs. Unity gain
is straight up.
The main output program is a mix of all inputs playing, and
either Aux 1 or Aux 2.
2. AUX 1/AUX 2 SELECTOR
Use this volume control to adjust the sound output level
to your speakers. Adjust the master level and the input
levels to average settings, not too high and not too low.
For example, if you find you have to turn the master volume
up high, then the input level controls might be set too low.
If the master volume becomes loud after a small rotation,
then the input level controls might be set too high.
6. STATUS LEDS
This high-quality toggle switch selects either Aux 1 or Aux
2 to be the auxiliary input passed through to the amplifier
section. The Aux 1 and 2 inputs on the rear panel are
unblanced RCA line-level connections.
These LEDs show:
OVERLOAD (RED)
SIGNAL PRESENT (AMBER)
The Aux master level control below the selector switch
increases or decreases the signal level of the selected Aux
input to the amplifier.
3. EQ-LOW

POWER ON (GREEN)
7. POWER
Turn this clockwise to boost the level of the low-frequency
range below 100 Hz. Turn it counter-clockwise to cut the
level. In the detented center position, there is no change in
level. The maximum boost and cut is 12 dB.
Use this switch to turn the unit on or off. The power is on
when the top of the switch is pressed, and off when the
bottom is pressed. Turn it off if you are not using the unit
for long periods of time.
4. EQ-HIGH
Turn this clockwise to boost the level of the high-frequency
range above 10 kHz. Turn it counter-clockwise to cut the
level. In the detented center position, there is no change in
level. The maximum boost and cut is 12 dB.

INPUT CONNECTORS
Inputs 1 and 2 each have four different styles of input
connections. Choose one which suits your system the best:
8. Combination XLR/TRS connector. This
can accept a male balanced XLR connector, a
balanced TRS or unbalanced TS 1/4" connector.
9. Phoenix (Euroblock) connector. This
three-pin connector accepts the positive, negative
and ground terminals of a balanced audio line. It
accepts a push-in connector for easy installation.
10. Terminal strip. This three-terminal connector
accepts the positive, negative and ground
terminals of a balanced audio line. Secure the
connections with the screws.
All inputs are designed to accept balanced or unbalanced
microphone-level signals, or may be configured to accept
line-level signals by means of the DIP-switch (see below).
11. GAIN pot and LED
This screwdriver-adjustable rotary potentiometer acts as a
trim control, and a red indicator LED displays the nominal
input level. With normal source material playing, adjust the
pot until the LED lights only occasionally during the loudest
moments of your program. (The LED will light 3 dB before
clipping.)
12. DIP switches
Input 1 has an eight-pole DIP-switch from which the inputs
(all four types) can be configured.
Input 2 has a seven pole DIP-switch,
identical to the first seven poles of
Input 1.

DIP switch details:
1. Mic/line (line-level is default). Select UP if using a
microphone, or DOWN if it is a line-level input such
as from a CD or DVD player. Note: You must set
DIP 2 to the same setting as DIP 1.
2. Mic/Line. Set this to whatever DIP 1 is set to. See
above for details.
3. Phantom Power. Select UP if using a microphone
that requires phantom power, otherwise, it is
important to keep this DOWN.
4. High-pass filter enable. The default position is
enabled (DOWN). This rolls off the low frequencies
below 120 Hz, at a rate of 12 dB per octave. Use
this to reduce low frequencies, such as from low
bass notes, microphone handling and stage noise.
It is useful when using smaller speakers that do
not reproduce the low frequencies well.
5. 10 dB pad enable. Select UP to reduce the input
level by 10 dB.
6. and 7. Ducking Threshold Select. Use these two in
combination to select the threshold when ducking
occurs. See Ducking Threshold and table below.
8. Transformer enable. Select UP to engage the inline audio transformer (input 1 only).
Ducking Threshold
DIP-switches 6 and 7 are used in combination with each
other to determine the threshold that the signals from input
1 or 2 must cross to initiate automatic ducking of the other
inputs. This table shows the combinations:
DIP 6

CAM160 / CAM80 – Ducking will take place within 300 mS of detecting that an
input signal has crossed the ducking threshold. This delay
also applies to the manual activation of the Priority circuit
by the use of external contact closures.
Inputs 3, 4, 5, 6
Inputs 3, 4, 5 and 6 have identical connections and
controls. (Input 3 is shown here.)
When the signal that initiated the ducking stops, or manual
activation has ceased, there will be a one second timeout
period to make sure it is completely over. When it is over,
the other inputs will ramp up to their original volume over
the next 0.5 seconds.

INPUT CONNECTORS
Inputs 3-6 each have two different styles of input
connections. Choose one which suits your system the best:
15. Phoenix (Euroblock) connector. This
three-pin connector accepts the positive, negative
and ground terminals of a balanced audio line. It
accepts push-in connectors for easy installation.

13.Priority Functions
16. Terminal strip. This three-terminal connector
accepts the positive, negative and ground
terminals of a balanced audio line. Secure the
connections with the screws.
Priority means that you can manually duck the other
channels using an external switch, and play only input 1 or
input 2.
Priority functions can be initiated by a user-supplied,
normally open, dry contact closure switch (or switches)
connected to the terminal strip (GND, Priority 1, Priority 2).
Connecting one leg of the switch to the GND
screw and the other side to either PRI 1 or
PRI 2 prepares the circuit. Closing the switch
actuates the specific priority, allowing input 1
or 2 to play
14.Chime Function
Chime functions can also be initiated by means of usersupplied, normally open, dry contact closure switch (or
switches) connected to the terminal strip (COM, Chime 1,
Chime 2).
Connecting one leg of the switch to the COM
screw and the other side to Chime 1 or Chime
2 prepares the circuit. Closing the switch
actuates the Chime.
– CAM160 / CAM80
All inputs are designed to accept balanced or unbalanced
microphone-level signals, or may be configured to accept
line-level signals by means of DIP-switches 1 and 2
(explained below).
17. GAIN pot and LED
This screwdriver-adjustable rotary potentiometer acts as a
trim control, and a red indicator LED displays the nominal
input level. With normal source material playing, adjust
the pot until the LED lights only occaisionally during the
loudest moments of your program. (The LED will light 3 dB
before clipping.)
18. DIP switches
Each input 3-6 has a five-pole DIP-switch
from which the inputs (both types) can be
configured. (These are identical to the first
five switches of inputs 1 and 2 described
on page 5.)

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.

19. Auxiliary Inputs 1 and 2
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.
20.Processing Loop
External processing is possible by using the Pre-out/Amp-in
processing loop. The PRE-OUT RCA connector is preamplifier, 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.
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.
24. 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.
25. 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.
26. 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.
21.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.
CAM160 / CAM80 – 29
27
HIGH IMPEDANCE
If you are using a constant-voltage distributed speaker
system, connect either the 25 V, 70 V, or 100 V output
terminal to the "+" side of the speaker system, and connect
the upper "GND" output terminal to the "–" side of the
speaker system.
The voltage of your speakers must equal the voltage of the
amplifier's output terminal ( 25 V, 70 V, or 100 V).
28
27. Output Connectors
This is a five-position barrier strip for connection of speaker
loads. Each terminal accepts bare wire from 22 AWG
to 10 AWG, or spade lugs sized for the same range of
conductors.
CAUTION: Make sure that you do not overload the
amplifier. This may cause overheating to the amplifier, and
possible damage to your speakers. To avoid overloading,
make sure that the taps on the speakers add up to no more
than 80% of the rated power of the amplifier being used
(CAM160: 128 watts, CAM80: 64 watts). For example, for
the CAM160, you could use a maximum of 12 speakers
with 10 watt taps (12x10 = 120 watts). For further
protection, use these figures as the maximum power sum
of all the speaker taps: CAM160: 100 watts, CAM80 50
watts.
Terminals are provided for 4 ohm low-impedance loads or
25, 70 and 100 Volt high-impedance loads.
CAUTION: To prevent the risk of electric shock, never
touch the bare wires coming from the OUTPUT TERMINALS
of the amplifier when it is switched on. When the
connections have been made, insulate the 25 V, 70 V, and
100 V terminals of the amplifier using the protective cover
supplied.
All outputs with the exception of the 4 ohm output are
transformer isolated.
GND and 25V are used to connect a string of 25V speakers.
Use Class II wiring:
LOW IMPEDANCE
To connect a speaker directly, connect the lower GND
terminal to the negative post of your speaker, and connect
the 4 ohm terminal to the positive post.
Make sure that your average speaker impedance is not less
than 4 ohm, as this may overload the amplifier.
The speaker output connectors are screw terminals. Use
16 or 18 gauge wire for connecting the amplifier outputs to
the speakers. Strip the wire back about 3/8" inch, loosen
the screw enough to loop the wire around the shaft of
the screw (clockwise), and tighten down the screw with a
screwdriver.

The unit seamlessly switches to the backup supply if
there's a power loss, allowing safety instructions and
emergency communications to continue. When both AC
power and 24 VDC power are connected, the AC power is
used and no current is drawn from the DC supply.
100V
Note: The unit will not charge the battery, so you should
have a dedicated charging system. Note also, that when
running on DC power, the output is lower than when
running on AC power.
28. AC Power
The CAM160 and CAM80 are fitted with a detachable IEC
socket for AC input.
Each unit is fitted with a universal power supply, allowing
it to operate from any AC mains supply from 100 to 240
VAC, 50-60 Hz.
A 6-foot U-Ground to IEC power cable is supplied.
An integrated, removable, AC input fuse is fitted just below
the IEC socket. To remove or inspect the fuse, first unplug
the power cord from the AC socket. Then use a small
screwdriver to gently pry open the rectangular fuse holder
and inspect or replace the fuse. Replacement fuses must
be of the same rating as the original fuse.
Low voltage fuses are located internally.
29. DC Power
These terminals allow the amplifier to be powered using 24
VDC emergency power supplies.
The unit will automatically switch to external DC battery
power if your local AC power fails. You will need to
connect an external 24 Volt battery to the DC battery
terminals.
24 VDC
Make absolutely sure the positive post of your battery
connects to the positive terminal, and the negative
post connects to the negative terminal. To minimize the
voltage drop across the wires and prevent overheating, use
at least 14 AWG insulated wire.
CAM160 / CAM80 – 5. THERMAL CONSIDERATIONS
The power amplifier within the unit is convection cooled
rather than fan cooled. Heat is drawn away from the
amplifier by the heatsink and radiated through the cooling
vents in the top and bottom cover.
When installing, be sure to allow sufficient air space
around the top and rear of the amplifier to allow
adequate cooling for the heatsink. Leave at least one rack
space above and below, and at least 6 inches behind the
chassis to allow proper ventilation.
If the amplifier should overheat, a thermal switch turns
off the power amplifier, allowing the heatsinks to cool
down. Once the amplifier has cooled to a safe operating
temperature, the thermal switch resets and reactivates
the amplifier. If this should occur, identify the cause of the
problem and take corrective action. For example:
• Provide better ventilation,
• Install a fan in the rack to move more air,
1/4" TRS Phone Plugs and Jacks
