Each channel shall deliver a minimum of 300W at 8, 550W at 4, 20Hz­20kHz, <0. 1% THD+N. In bridged-mono mode, it shall deliver 1000W at 8, 20Hz­20kHz, <0. 1% THD+N. The amplifier shall be front-to-side tunnel-cooled, with one 110 CFM AC fans. 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 X46. 6 with an input sensitivity of 1. 0V, for rated power at 8. The hum and noise level shall be greater than 105dB below rated output, A-weighted. SMPTE IMD shall be less than 0. 1%, rated power at 8. The amplifier shall have a class AB output. The frequency response shall be greater than 20Hz­20kHz, +0/-0. 3dB (1W/8). The amplifier shall operate at 100­240VAC, 50­60Hz (configured at factory). [. . . ] *Three-year Warranty with two additional years, if Registration Card is sent to Crest Audio.
