PECIFICATIONS

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 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, 8
