Getting Started
The COM12/COM24 public address amplifier can be switched on by pressing the power button
on the front panel. The blue ‹ ON › led will light up if the device is powered-up.
On the front panel you can route the input signals to a specific zone output simply by pressing the
routing button of the zone output. If you want to route the input signals to all zone outputs, press
the ‹ All › button. By pressing the routing buttons a second time, the routing will be undone. A pre-
announced chime can be played by pressing the ‹ Chime › button on the front panel.
The volume of the input signals can be controlled by turning the volume knobs of the input
signals on the front panel of the COM12/COM24. The master volume knob and the 2 band tone
control let you adjust the volume, bass and treble of the output signal. A VU-bar indicates the
signal level of the output signal.
On the rear panel, the gain of the input channels and the remote microphone can be adjusted. The
volume of the ‹ chime › and the ‹ music on hold › function can also be adjusted on the rear panel.
The output section on the rear panel of the COM12/COM24 has 5 high impedance zone outputs
for 100V lines and 1 low impedance zone output to connect a 4ohm speaker (or two 8 ohm
speakers in parallel).
