Architects' & Engineers' Specifications:

The power amplifier shall consist of 2 channels. Each channel will delver a minimum of (450 / 595 / 800) watts at 8 ohms, (700 / 965 / 1,350) watts at 4 ohms, (1,850 / 2,800 / 4,000) watts at 2

ohms, 20 Hz – 20 kHz. In Bridged mono mode, it will deliver a minimum of (1,850 / 2,800 / 4,000 W) at 4 ohms, 20Hz – 20 kHz. It shall weigh (32.6 / 39.8 / 43.3) lbs.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 1.32 / 1.7 / 1.88 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 / -111 dB / -112 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 for the CC 1800 and 10 Hz - 50 kHz, +0, -3 dB for the CC 2800/4000 at full rated output power @ 4 ohms, .1% THD. The amplifier will

operate at either 120 VAC, 60 Hz (safe operating range 100-132 VAC) or at 230 VAC, 50 Hz (safe operating range 200-264), voltage selection determined at factory. Maximum current draw at

120 V shall be no greater then 15 A, both channels driven continuously into a 2 ohm load at 1/8 power. Front panel indicators shall include LED indicators for signal present, ACL (automatic clip

limiting),Temp, and Active status. Front panel attenuators will be recessed and detented. Input connectors shall be XLR per channel. Output connectors shall be 5-way binding posts and Speakon,

per channel.The packaging of the amplifier shall allow for standard rack mounting without requiring space between similar units as long as the rack is properly ventilated. Dimensions main chassis

shall be 19" wide (482.6mm), 14.875" deep (482.6mm), 3.5" high.The amplifiers shall be designated the Crest Audio model CC 1800, CC 2800 and CC 4000.
