Crest Audio CA 4 1000W

Professional sound at its best.

The Crest Audio CA 4 power amplifier is designed to achieve unsurpassed sonic performance and long-term reliability. With professional power-handling capabilities and exceptional low-end response this rack amp is an ideal choice for installations and touring applications that demand the finest audio quality. The CA 4 provides high power output coupled with true clarity, and is well-suited for high-powered subwoofers and passive full range systems.

Absolute sonic accuracy is the hallmark of the Crest Audio power 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 4 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 Series' combination of value and sonic quality.
