Crest Audio CA 18 5000W Power Amplifier

Price: ₦ 899,999.00

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.
