Introduction
· Power Output
The MC352 consists of two separate power amplifier chan-
nels, each capable of 350 watts into 2, 4 or 8 ohm speakers
with less than 0.005% distortion.
· Full Balanced Circuity
The MC352 is fully balanced from inputs to outputs. Each
channel consists of two matched power amplifiers operat-
ing in push-pull with their outputs combined in a McIntosh
Autoformer. The double balanced configuration cancels
virtually all distortion.
· Power Guard
Both channels include the patented McIntosh Power Guard
circuit that prevents the amplifier from being overdriven
into clipping with its harsh distorted sound that can also
damage your valuable loudspeakers.
· Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage protection
circuits ensure the MC352 will have a long and trouble free
operating life. Built-in thermal protection circuits guard
against overheating.
· Patented Autoformers
McIntosh designed and manufactured Output Autoformers
provide an ideal match between the amplifier output stages
and speaker loads of 2, 4 and 8 ohms. The Autoformers
also give perfect DC protection for your valuable loud-
speakers.
· Illuminated Power Meters
The illuminated power output watt meters on the MC352
are peak responding, and indicate the true power output of
the amplifier. The Peak Hold Mode allows the meters to
temporarily stay at the highest power output and then
slowly decay.
Now you can take advantage of traditional McIntosh stan-
dards of excellence in the MC352 Power Amplifier. Two
350 watt high current output channels will drive any high
quality loudspeaker system to its ultimate performance.
The MC352 reproduction is sonically transparent and abso-
lutely accurate. The McIntosh Sound is The Sound of the
Music Itself.
