The Crest Audio CA4 professional power amplifier is designed to achieve unsurpassed sonic performance and long-term reliability — even when operating under extreme stress — in touring or fixed installation applications. 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 AB output circuit design. Wide-bandwidth output devices assure detailed, transparent high frequency response. And, thanks to Crest’s exclusive IGM circuit, the CA4 amplifier will drive 2 Ohm loads safely without compromise in performance.

The Crest Audio CA4 amplifier is built exclusively in Crest’s own USA manufacturing facility, with internal components selected for premium quality and proven durability. Each modular subassembly is pre-tested, and the assembled Crest Audio CA4 amplifier receives a rigorous “hot room” burn-in before thorough final checkout on precision test equipment.
