Power guard ® A waveform comparison circuit continuously monitors both input and output signals. Power Guard dynamically adjusts the input level to avoid clipping while preventing harsh sounding distortion. sentry MonItor ® Fuse-less short-circuit protection circuit disengages the output stage before current exceeds safe operating level – resets automatically. outPut autoForMers Unique McIntosh technology delivers the full rated amplifier output with the least possible distortion into loudspeaker impedances of 2, 4, or 8 ohms; you get all the power you paid for and the freedom to choose any loudspeaker. wattMeter Swift, accurate response reveals program peaks so staying within the power limits of your loudspeakers is easy.
