Exclusive McIntosh Power Assurance System:
A collection of technologies that enhance performance and reliability while protecting the amplifier and loudspeakers.

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 Autoformer:
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 to make staying within the power limits of your loudspeakers is easy.
