MC501
Monoblock Power Amplifier

The MC501, 500 watt mono block amplifier has a new and bold, yet unmistakably McIntosh look. It features 3-dimensional glass and new cool-running, ultra long life, fiber optic LED lighting. The chassis gleams in polished stainless steel. Upward facing connectors at the back make attaching cables easier. The extraordinary quad-differential amplifier design reduces noise and distortion to record low levels. Total Harmonic Distortion: 0.005% maximum from 250 milliwatts to rated power output for 2 channels. Specifications are very conservative.

MC501 Monoblock Power Amplifier Features

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 MONITORTM

Fuse-less short-circuit protection circuit disengages the output stage

before current exceeds safe operating level – resets automatically.

 

OUTPUT AUTOFORMERTM

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.
