The audio power amplifier shall be solid state design employing 8 vertical
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 50 watts into an 8 ohm load and
55 watts into a 4 ohm load with both channels driven. In bridged mono mode,
the amplifier shall produce at least 110 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 a screw type terminal barrier strip 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 either 115V/60Hz or 230V/
50-60Hz AC mains.
The amplifier’s front panel shall provide Full Range 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%, and thermal protection should the heatsink temperature become
excessive.
The amplifier shall fit standard 19” EIA rack mounting requirements utilizing 1-
rack space. The dimensions shall be 19” Wide, 8
