The Coliseum CA1 public address amplifier has been designed specifically for installations where a 
versatile paging system with high quality music playback is required.

Ideal for restaurants, small clubs, offices and retail environments where a simple and reliable system
capable of servicing multiple paging zones is required. Multiple inputs for microphone or source material,
and voice activated paging from either a microphone or telephone matrix means the CA1 can be used in
virtually any application.

XLR / TRS balanced combi-jack inputs and attenuated RCA unbalanced inputs ensure the CA1 system can
interface with any source (CD, Cassette, Satellite Tuner, DVD or video system) your installation may require.

Capable of driving either a 4-ohm speaker load, or four separate 70-volt speaker systems (one ‘system’
per zone), the CA1 system delivers 180 watts (mono). A pre-amp output is available to feed an auxiliary
power amplifier or active subwoofer to enhance the system, or to feed video or audio recording equipment.
