Yorkville 4334197053 CA1 70V 6-Channel PA Amplifier

The Yorkville CA1 is a 6-channel public address amplifier delivering 180 watts of mono power, built for permanent installation in churches, boardrooms, conference rooms, and similar spaces. Its input section combines XLR/TRS balanced combi-jack connectors with attenuated RCA unbalanced inputs on each channel, making it straightforward to integrate microphones alongside line-level sources like CD players, satellite tuners, and video systems. Three channels offer user-selectable phantom power, enabling direct connection of condenser microphones—the type most often found on podiums and clip-on lavalier mics—without requiring separate preamp hardware.

On the output side, the CA1 supports either a standard 4-ohm speaker load or four independent 70-volt speaker zones, giving installers the flexibility to distribute audio across multiple rooms or areas from a single amplifier. A pre-amp output is included for feeding an external power amplifier, active subwoofer, or recording equipment, allowing the system to be expanded as needs grow. Housed in a rack-mountable steel chassis, the CA1 is designed for reliable long-term operation in fixed installations where versatile mixing, phantom power, and zoned distribution are essential from a single unit.
