The power amplifier shall consist of 2 channels. Each channel will delver a minimum of 825 watts at 8 ohms, 1450 watts at 4 ohms, 2250 watts at 2 ohms, 20 Hz – 20 kHz. In Bridged mono mode, it will deliver a minimum of 2900 watts at 8 ohms, 4500 watts at 4 ohms, 20Hz – 20 kHz. It shall weigh 24 lbs (10.90 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 1.87 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 -110 dB “A” weighted. The amplifier shall have a class H output stage with a switch power supply. The frequency response shall be greater than 10 Hz – 100 kHz +0, -2 dB at 1 watt at full rated output power @ 4 ohms .05% 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. 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 (483 mm), 12.25" deep (311 mm), 3.5" high (89 mm). The amplifiers shall be designated the Crest Audio model Pro 8200.
