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.
