At 300 watts per channel the new McIntosh MC303 Three Channel Power Amplifier with Autoformers delivers its maximum rated output power into 2, 4, or 8 ohm loads for the lowest noise and distortion performance possible. Premium cosmetics featuring a ½” thick glass faceplate, custom machined and anodized aluminum handles, and a mirror polished stainless steel chassis are standard equipment on the MC303. Power Guard, a McIntosh circuit innovation, maximizes sound quality at high power levels while our Sentry Monitor feature provides continuous short circuit protection of the amplifier and connected loudspeakers. A triple bank of Peak Reading Watt Meters provides instant recognition of power output and may be switched off for theater use.

MC303 Three Channel Power Amplifier Features:

Three 300 Watt Channels

60 Amps Output Current

Large Gold Plated Five-Way Binding Poss

A collection of technologies that enhance performance and reliability while protecting the amplifier and loudspeakers.

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.

Fuse-less short-circuit protection circuit disengages the output stage before current exceeds safe operating level – resets automatically.

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.

Swift, accurate response reveals program peaks so staying within the power limits of your loudspeakers is easy.
