Crest Audio CC Series amplifiers are designed to achieve unsurpassed sonic performance and long-term reliability 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. Wide-bandwidth output devices ensure detailed, transparent high frequency response. And, thanks to Crest's exclusive IGM™ circuit, the CC Series will drive 2 Ohm loads safely without compromising performance.
The power amplifier shall consist of 2 channels. Each channel will deliver a minimum of 450 watts at 8 ohms, 700 watts at 4 ohms, 1.850 watts at 2 ohms, 20 Hz - 20 kHz. In Bridged mono mode, it will deliver a minimum of 1.850 watts at 4 ohms, 20Hz - 20 kHz. It shall weigh 32.6 lbs. (14.8 kg). The amplifier shall incorporate protection circuitry against output short circuits, DC voltage on outputs, thermal overload and load protection due to any form of amp failure. It will include impedance sensing circuitry, a RMS clip limiter and Autoramp signal control. The amplifier shall have a sensitivity of 1.328 volts (x40) at the input, which will deliver full rated output power in any output configuration. Gain can be changed to x20. The hum and noise level shall be greater than -106 dB "A" weighted. The amplifier shall have a class H output stage with a linear power supply. The frequency response shall be greater than 10 Hz - 35 kHz +0, -3 dB at full rated output power @ 4 ohms, .1% THD.
