The power amplifier shall use digital Class-D technology with active PFC (power factor correction) circuit to achieve a power output of 480 W. The unit shall include 1 line input, 1 speaker line input, 1 line output and 1 switchable 100 V (21 Ω) line or 4 - 16 Ω low impedance outputs.

The line input shall be fixed transformer balanced 600 Ω input via 2 RCA pin jack.

The speaker line input shall be 100V (65 kΩ) line via a 2-pin removable temirnal block.

The line output shall be unbalanced 600 Ω output via 2 RCA pin jack.

The speaker line output shall be switchable 100V (21 Ω) line or 4 - 16 Ω low impedance line via a 3-pin removable temirnal block.

The unit shall have a remote control input for the unit to be powered on and off remotely.

It shall also be equipped with an emergency control input to turn the unit's power on and deliver audio signals at the line output and speaker line output while bypassing the Master Volume Control.

There shall be a visual five-LED output level meter and visual LED indication of power, over current, thermal protection, emergency broadcast.

Power requirements shall be 220 - 240 V AC via a supplied power cord. The device shall have a frequency response of 50 Hz – 20 kHz.
