Overview

Ideal for power-eating subwoofers or passive full-range systems.

Designed to achieve unsurpassed sonic performance and long-term reliability, the Crest Audio CA 12 power amplifier has professional power-handling capabilities and exceptional low-end response this amplifier an ideal choice for installations and touring applications that demand the finest audio quality. The rackmountable CA 12 provides high power output coupled with true clarity, and is a well-suited power amp for high-powered subwoofers and passive full range systems.

Absolute sonic accuracy is the hallmark of every Crest amplifier. Bass is solid and defined to the limits of audibility, with ample current reserves delivered by an "over-engineered" power supply and advanced Class H circuitry. Wide-bandwidth output devices assure detailed, transparent high frequency response. And, thanks to Crest's exclusive IGM circuit, the CA 12 will drive 2 Ohm loads safely without compromise in performance.

The CA series provides tremendous value in proven amplifier technology. CAs form the backbone of discriminating rental systems and high-power club installations worldwide. Auditoriums, churches, regional tour sound companies and mobile DJs are all ideal candidates for the CA 12 amp's combination of value and sonic quality.
