User manual CREST AUDIO PRO SERIES 6001 SPECIFICATIONS

[. . . ] The 6001 is fully compatible in design with other Crest Audio Professional Series amplifiers, Octal Socket Accessories, and the NexSys® computer-controlled audio system. 6001 Features · · · · · · · · · · NexSys-ready Toroidal power transformer Tunnel cooling Variable speed DC fan High thermal mass heat sinks Balanced XLR inputs 5-way output binding post connectors Stereo/Parallel/Bridged Mono mode selector switch Rear panel ground lift jumper Extensive protection circuitry: - Clip Limiting prevents speaker damage with gentle gain reduction at clip threshold. - IGM (Instantaneous Gain Modulation) monitors connected loads to detect conditions that may overstress output devices, allowing safe operation into nominal 2 impedances. - AutoRamp gradually increases gain to attenuator setting level when amplifier is turned on.

(23. 10 kg. ) 5 years, parts and labor Architect's & Engineer's Specifications The power amplifier shall have two channels. Each channel shall deliver a minimum of 400 watts at 8 ohms, 600 watts at 4 ohms, and 720 watts at 2 ohms; 20Hz - 20kHz, <0. 05% THD+N. In bridged mono mode, it shall deliver 1200 watts at 8 ohms and 1440 watts at 4 ohms, 20Hz 20kHz, <0. 05% THD+N. The amplifier shall be rear-to-front tunnel-cooled, with a variable-speed DC fan. The amplifier shall have circuitry to protect itself and the speaker load from output short circuits, DC voltage on outputs, and thermal overload. The amplifier shall include circuitry to gradually increase gain to attenuator setting levels when the amplifier is turned on, and circuitry for impedance sensing and clip limiting. The amplifier shall have a voltage gain of X40 with an input sensitivity of 1. 2V for rated power at 4 ohms. The hum and noise level shall be at least 100dB below rated output, "A" weighted. SMPTE IMD shall be less than 0. 1% at rated power, 60Hz and 7kHz. The amplifier shall have a class AB output stage with a modulated power supply. The frequency response shall be greater than 20Hz20kHz, +0/-0. 3dB (1W/8). The amplifier shall operate at 100-240V, 50-60 Hz AC (configured at factory). Maximum current draw shall not exceed 21 amperes at 120VAC, (circuit breaker limited), with both channels driving continuously into a 4 ohm resistor. The amplifier front panel shall include Active, Temp/DC, Signal Present and Clip/Limit LED indicators for each channel, a combination power switch/magnetic circuit breaker and recessed and detented gain pots. Rear panel input connectors shall be actively balanced and have female XLR-type, 3-pin connectors (pin 3+).
