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 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 so staying within
the power limits of your loudspeakers is easy.
