MC312 Power Amplifier

The McIntosh MC312 is a 300-watt-per-channel solid-state power amplifier for two-channel systems. Its McIntosh Autoformers provide the rated output into 2-, 4-, or 8-ohm loudspeakers, allowing the amplifier to maintain its specified power across those loads.

Quad Balanced circuitry, balanced and unbalanced inputs, and two front-panel Watt Meters form a direct and symmetrical stereo layout. Power Guard, Sentry Monitor, thermal protection, and Power Control support reliable integration with a McIntosh preamplifier and the chosen loudspeakers.
