1. INPUT LEVEL CONTROLS: Controls in the input level control for
the corresponding channels.
2. MASTER LEVEL CONTROL: This controls the final output level
before sending to the output connectors.
3. MASTER OUTPUT INDICATORS: The green LED above the
Master level control will light up when the output signal exceeds -40dB
indicating that a signal is present. The red LED indicator will light
up when the output signal reaches high peaks with the potential of
causing distortion.
4. BASS CONTROL: Turning to the right will increase the response of
low-frequency signals (100 Hz) in your main audio signal. Turning to
the left will decrease the response of low-frequency signals.
5. TREBLE CONTROL: Turning to the right will increase the response
of high-frequency signals (10 kHz) in your main audio signal. Turning to
the left will decrease the response of high-frequency signals.
6. POWER BUTTON AND INDICATOR: This button turns the CMx
mixer/amplifier on. When the unit is turned on, the LED indicator will
illuminate to indicate as such. Be sure that the mixer amplifier is turned
on after all other input sources
7. INPUT AMP CONFIGURATION DIP SWITCHES: These DIP
switches have a number of different functions. See reverse for details.
8. INPUT 1 TERMINAL: This is a 5-pin Phoenix-type connection with
3 pins for balanced input signals and 2 connectors for priority push-to-
talk button connection. The input accepts direct connection of line or
microphone inputs as selected by the mic/line DIP switch.

9. INPUT 1 VOX THRESHOLD CONTROL: This control adjusts the
level at which the Input 1 signal should be before other signals are
muted. This only works when the CH1 VOX DIP switch is turned on.
10. RCA INPUTS: These inputs accept stereo unbalanced line-level
RCA input signals. The input signals received through these connectors
are summed.
11. TELEPHONE (MOH) OUTPUT AND CONTROL: This 4-pin
Euroblock connector provides two different output possibilities. The
8 ohm side is for 1W output to external speakers, while the 600
ohm connectors are for connecting private branch exchange (PBX)
telephone systems for on-hold music. For further info on wiring, see the
Output Wiring section.
12. PREAMP OUTPUT TERMINAL: This balanced 3-pin Phoenix type
connection sends the main signal to external devices. The output signal
level is dependent on the master level control. For further info on wiring,
see the Output Wiring section.
13. AMPLIFIER OUTPUT: Speakers can be connected to this output
terminal. Connections available include COM (common), 70V, 100V
and 8 ohms. These input connections can accept terminal forks up to
10 AWG. For further info on wiring, see the Output Wiring section. The
GA335 offers 35 Watts of power while the GA460 offers 60 Watts.
14. POWER INLET: This is for a standard IEC power cable. Please
connect the cable to a suitable AC power outlet. While the CMx series
offers a universal power supply, be sure to check local voltage levels
before connecting the unit to ensure they correspond.
