70V Installation AmplifierProfessional Public Address / Installation Amplifier


Versatile input mixing capabilities make the CA1 the solution for small churches, boardrooms and conference room PA applications. Unlike most installation amplifiers in this class, user 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 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.
