(9.98kg) UL ® C UL ® The audio power amplifier shall be solid state design employing 4 lateral power MOSFET output devices. It shall be constructed on a 16 gauge steel chassis utilizing convection cooling and be technician friendly using modular construction. Each channel shall be rated for a minimum of 75 watts into an 8 ohm load and 85 watts into a 4 ohm load with both channels driven. In bridged mono mode, the amplifier shall produce at least 170 watts into an 8 ohm load. A switch shall be provided for stereo or bridged mono operation and all power ratings shall be measured from 20Hz-20kHz with less than 0.2% THD. The amplifier’s back panel shall provide Balanced inputs via combination XLR and 1/4” phone jacks. The back shall also utilize gold-plated 5-way binding posts for output connectors and a switch to isolate or connect the signal ground to the chassis ground. The amplifier shall include a 3-wire grounded AC line cord and UI power transformer operating on 120V/60Hz AC mains. An optional transformer for 230V 50-60Hz operation shall be available. The amplifier’s front panel shall provide level controls with optional security covers. The front shall also incorporate a lighted main power switch and indicators for each amplifier channel. The indicators shall display signal present when 30mV of signal is detected, signal clipping when distortion rises above 1%, thermal protection should the heatsink temperature become excessive, and short circuit protection in case a problem on the speaker system arises. The amplifier shall fit standard 19” EIA rack mounting requirements utilizing 2rack spaces. The dimensions shall be 19” Wide, 81⁄2” Deep, 31⁄2” High, and be finished in black with a net weight of 21.6 pounds. It shall be a Hafler P1500.
