ARCHITECT’SAND ENGINEER’SSPECIFICATIONS
The audio power amplifier shall be solid state design employing 8 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 150 watts into an 8 ohm load and
200 watts into a 4 ohm load with both channels driven. In bridged mono mode,
the amplifier shall produce at least 400 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 exces-
sive, and short circuit protection in case a problem on the speaker system
arises.
The amplifier shall fit standard 19” EIA rack mounting requirements utilizing 2-
rack spaces. The dimensions shall be 19” Wide, 97⁄8” Deep, 31⁄2” High, and be
finished in black with a net weight of 23 pounds. It shall be a Hafler P3000.
