PECIFICATIONS

The audio power amplifier shall be a fully balanced, discrete solid state

design employing JFET inputs and 16 lateral power MOSFET output devices. It

shall be constructed on a 16 gauge steel chassis utilizing convection air

cooling.

Each channel shall be rated for a minimum of 250 watts into an 8 ohm load and

375 watts into a 4 ohm load with both channels driven. In bridged mono mode,

the amplifier shall produce at least 750 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 a switch to select Unbalanced inputs

via gold-plated RCA jacks or 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 a switch to operate the UI power transformer on 120V/60Hz AC mains. An

optional transformer for 230V 50-60Hz operation shall be available.

The amplifier’s front panel shall incorporate a lighted main power switch and

have rack handles. The amplifier shall fit standard 19” EIA rack mounting

requirements utilizing 3-rack spaces. The dimensions shall be 19” Wide, 12
