15. INPUTS
These inputs allow you to connect balanced XLR plugs
from microphones or 1/4" TRS or TS plugs from line-level
sources.
INPUT 1 has "Voice Priority" over the other inputs. If an
announcement is made using a microphone connected to
INPUT 1, then the other inputs are over-ridden.
16. AUX INPUTS
These left and right unbalanced RCA inputs allow you to
connect your audio sources, such as tuner, CD player, DVD
audio, tape deck, etc. They accept stereo line-level input
signals, and sum them to mono. This input is suitable for
connecting most common line-level sources. Use high-
quality, two-conductor shielded cable for the connections.
17. MAIN IN, PREAMP OUT
These two connections are normally joined using a U-shaped
jumper.
Note: If the U-shaped jumper is missing, then there will
be no output from your unit.
Use the PREAMP OUT to send a line-level signal to an
external amplifier, or to an external processor or equalizer.
The output is affected by the Level controls, but not by the
Master Volume or Tone controls.
The output from an external processor can connect to
MAIN IN. The Master Volume and Tone controls will adjust
any signals before they reach the main amplifier section.
18. OUTPUT TERMINALS
This terminal is normally covered by a protective cover.
Remove the two screws and the cover while making or
undoing connections. Securely refit the cover when you
have finished making the connections.
The five output terminals are labeled COM, 4
Ω
, 25 V, 70 V
and 100 V.
CONSTANT IMPEDANCE
To connect a speaker directly,
connect the COM terminal
to the negative post of your
speaker, and connect the 4
Ω
terminal to the positive post.
Make sure that your
average speaker impedance
is not less than 4
Ω
, 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.
CONSTANT VOLTAGE
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 "COM"
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).
Make sure that the taps on the speakers add up to no
more than 90% of the rated power for the amplifier
being used CAM150: 135 watts, CAM60: 54 watts.
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.
