Legacy Series - CA12

12x 50w Distribution Amp

The Coliseum CA12 multi-channel amplifier is the ideal solution for powering any complex multi-zone, multi-speaker installation. Designed with versatility in mind, the CA12 can be configured as 12 single channel 50-watt amplifiers, each capable of driving 4 or 8-ohm loads or 70-volt speakers. The 12 mono channels can be configured in six stereo pairs for easy hook up to stereo source mixers. Stereo channels can be bridged mono, effectively turning the CA12 into six 100-watt (at 8 ohms) amplifiers.
