Crest CA9 2 channel pro audio amplifier in original factory packaging. The amp works and sounds great. I used 2 of them in a bi-amped small outdoor PA system and took them out of service 6 years ago.
Since then, they've been in their boxes. Excellent condition, low hours of usage and always mounted in an equipment rack. This is the second of my 2 Crest CA9 amplifiers.
Power output: 550 watts per channel into 8? (stereo), 1600 watts into 8? Frequency response: 20Hz to 20kHz. Total harmonic distortion: 0.1%.
