Architect Specifications 6250 The power amplifier shall be a multichannel unit consisting of six independent channels. Each amplifier shall be able to deliver 150 watts into 8 ohms, or 250 watts into 4 ohms. In addition, bridged pairs shall be able to output 500 watts each into 8 ohms. Also, when pairs are bridged, the unit shall provide 500 watts capable of driving a 70 volt system without the use of external transformers. The amplifier shall have a gain of 30.1dB and an input sensitivity of 1.05 Volts RMS for full rated output. Frequency response shall be 20Hz to 20kHz +/- 0.5dB at 8 ohms. The unit shall be stable into any load, including pure capacitors and inductors. Hum and noise shall be at least 100dB below full output (A-weighted) and SMPTE intermodulation distortion shall be less than 0.2%. Total Harmonic Distortion (20Hz - 20KHz at 8 ohms) shall be less than 0.2%. Each amplifier channel shall be supplied with an input attenuator located on the rear panel input module. Each pair of inputs shall have a bypassable high pass filter of 12dB/octave at 50Hz, a switch to select stereo or mono mode and a switch to select dual or bridge mode. There shall be an input ground switch located on the input module to select chassis or floating ground operation. The inputs shall be active balanced design, with an impedance of 10K ohm accessible with combination XLR - 1/4” jacks and eurobloc connectors. The outputs shall be terminated with a 5-way binding post connector. Individual channel indicators for protect, thermal overload, clip and signal present shall be LEDs located on the front panel. Cooling shall be supplied by a temperature sensitive three-speed fan drawing air from the front of the unit and exiting through the rear. The unit shall be capable of operation by means of its own builtin power supply connected to 110 - 125V AC, 220 - 250V AC, 50/ 60Hz. Dimensions of the unit shall be 19”L X 5.25”H X 16.5”D. The chassis shall be constructed from steel with an aluminum face panel and weigh 45lbs. The unit shall be the Powerflex™ 6250 manufactured by Ashly Audio, Inc.
