CA12 Multi-Zone Professional PA Amplifier

Introduction

The CA12 is a major step forward in installation amplifier technology. Twelve mono Zone power amplifiers, featuring 85% class D design technology, can operate as 6 independent Zone amplifiers. Self-explanatory Input and Output connections are easy to follow since any of the 12 mono amplifiers can be connected to either 70-Volt, 8-Ohm or 4-ohm speaker circuits.

Each of the 12 mono amplifiers has their own input and output connectors and level controls. Up to 6 stereo Zones (4-ohm or 70-Volt at 50 Watts / channel), 6 mono/bridged Zone amplifiers (110 Watt bridged 8-ohm or 140-Volt). Each Zone can be configured independently allowing a combination of Stereo 4-ohm or 70 Volt and Mono/Bridged 8-ohm or 140 Volt Zones. Dual-function LEDs on the front panel provide both activity and Clip indication for each pair of amplifiers, which also have their own button-selectable Limiter; Stereo/Bridge modes and 4-ohm/70V modes are also selectable.

The Ch. Input Line/Bus switch selects between either the Bus Input (button depressed) or the individual Zone’s Input signal. Additional features include: any amplifier with no signal at its input is automatically shut off and the CA12 is able to operate either on 120V/60Hz or 220V/50Hz AC mains.

Features and Functions

AC Mains. The CA12 comes configured to connect to 115V/60Hz mains. For use with 230V/50Hz mains set the rear panel Voltage Select switch to 230V (also, replace the T10.0AL/250V fuse with a T5.0AL/250V fuse).

Front Panel

1. Left/Mono and Right Controls

These controls regulate the level for each amplifier. For the Zones set up in Mono/Bridge mode only the Left/Mono Control will affect the level.

2. On/Clip LED

The individual channel’s On/Clip LED will flash to indicate activity, flashing red will indicate clipping. Reduce levels if clipping is indicated (the LED does not indicate which Zone channel is clipping).

3. Power

 

This switch turns the AC mains On or Off.
