Features sophisticated protection circuitry (from shorted, open, or mismatched loads, input and high frequency overloads), 5-way fault indicator, red LED on each channel that turns on when distortion becomes audible, green signal-present LED that flashes when the level is extremely low (indicating cabling problems), and detented level controls. Mode select switch for stereo or bridged; 3-speed fan; and electronically balanced XLR inputs; touchproof binding post and Speakon outputs; all in a rugged steel chassis designed to handle serious road use.
