Crest Audio CA2

Description
The Crest Audio CA2 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.
