The McIntosh MC303 is a formidable 3-channel solid-state power amplifier, providing a robust 300 Watts per channel into 2, 4, or 8 Ohms. Designed for the critical front (LCR) channels in a home theater, it ensures dynamic and distortion-free performance. Its hallmark McIntosh Autoformer™ guarantees optimal power delivery regardless of speaker impedance.

Equipped with Power Guard® to prevent clipping and Sentry Monitor™ for short-circuit protection, the MC303 is built for reliability. It features balanced XLR and unbalanced RCA inputs, plus heavy-duty binding posts. Aesthetically, it showcases a polished stainless steel chassis, black glass front panel, and three iconic blue McIntosh Watt Meters. With an ultra-low 0.005% THD, the MC303 delivers powerful, precise, and immersive audio for cinematic excellence.

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.
