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. Selectable phantom power is available on three channels to drive condenser microphones, the type most commonly used on podiums or as a lavaliere (tie clip) microphone

XLR / TRS balanced combo-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

Constant Voltage (70-Volt) Audio Systems

Audio distribution systems, especially those commonly used in department stores, warehouses, restaurants, etc., require that many loudspeakers be driven from a single audio amplifier over long runs of speaker wire.  The "constant voltage" or "high impedance distribution" audio systems can be complex to understand at first, however, provides many advantages. Learn how to design your own 70-volt or 25-volt loudspeaker system.Â
