Highlights of this powerhouse amp:

Producing a minimum 400 watts per channel in stereo, 800 watts in mono, the MC402 delivers power that is fully balanced from input to speaker output. The extraordinary quad-differential design of the MC402 actually consists of four complete amplifier circuits. Each channel contains two amplifier circuits, each the mirror image of the other, whose outputs are combined in the unique McIntosh Output Autoformer® resulting in totally balanced operation from input to speaker output and the cancellation of virtually all noise and distortion.

The exclusive McIntosh Output Autoformer® is a handcrafted matching device that provides an ideal impedance match for all speaker types regardless of their rated impedance. Any departure from an optimum impedance match increases stress on the amplifier which threatens a rise in distortion as well as a reduction in the life expectancy of the amplifier. McIntosh Output Autoformers® enable the MC402 to operate at maximum efficiency and to always deliver full power, without stress, to any type of loudspeaker.

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
