Overview

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.

Key Features

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.

Pros & Cons

👍 Pros

  • Six input channels with both balanced XLR/TRS and unbalanced RCA connections handle a wide variety of sources
  • User-selectable phantom power on three channels supports condenser microphones without external preamps
  • 70-volt output with four independent zones simplifies distributed speaker installations
  • Pre-amp output allows system expansion with additional amplifiers or recording equipment

👎 Cons

  • 180 watts mono output may not be sufficient for larger venues or high-volume applications
  • No built-in wireless or Bluetooth connectivity for modern source devices
  • Single mono output means it cannot deliver discrete stereo sound to listening areas
