EXCLUSIVE MCINTOSH POWER
ASSURANCE SYSTEM
A collection of technologies that
enhance performance and
reliability and protect the amp and
the loudspeakers.
Power Guard clipping protection
A waveform comparson circuit
continuously monitors both input
and output signals and dynamically
adjusts the input level to insure
maximum output power while
preventing harsh sounding
clipping distortion.
Sentry Monitor current protection
continually senses the voltage and
current of the output stage and
confines it to a safe limit, without
limiting power output.
Thermal cutouts protect your amp
from overheating if cooling air is
blocked and transistors
become too hot.
DC failure protectionguards
speakers against output circuit
failure. The output autoformer
prevents DC from reaching
the speaker.
Turn-on delaydelays operation for
about two seconds after turn-on, to
silence any pops or thumps
generated by other equipment.
Soft Start inrush protection
eliminates component stress
during turn-on. Thermistors in the
power transformer act as a
cushion against inrush current.
Soft Start is one of many details
that contribute to the remarkable
longevity of McIntosh equipment.
