Overview

The master of subwoofers!

The Crest Audio CA 18 professional power amplifier is designed to achieve unsurpassed sonic performance and long-term reliability. With 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 CA 18 provides high power output of 5000 watts coupled with true clarity, and is well-suited for high-powered subwoofers and passive full range systems.

Absolute sonic accuracy is the hallmark of every rack mount 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 (Instantaneous Gain Modulation) circuit, the CA 18 will drive 2-ohm loads safely without compromise in performance.

The CA series by Crest Audio 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.
