Performance Features
Introduction
•••••
Power Output
The MC402 consists of two separate power amplifier chan-
nels, each capable of 400 watts into 2, 4 or 8 ohm speakers
with less than 0.005% distortion.
•••••
Exclusive Double Balanced Circuity
Each channel of the MC402 consists of two balanced
power amplifiers operating in push-pull with their outputs
combined in a McIntosh Autoformer. This double balanced
configuration from input to output cancels virtually all dis-
tortion.
•••••
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 provide perfect DC protection for your valuable Loud-
speakers.
•••••
Patented Power Guard
Both channels include the patented McIntosh Power Guard
circuit that prevents the amplifier from being over driven
into clipping, with its harsh distorted sound that can also
damage your valuable Loudspeakers.
•••••
Patented Sentry Monitor with Thermal Protection
McIntosh Sentry Monitor power output stage protection
circuits ensure the MC402 will have a long and trouble free
operating life. Built-in Thermal Protection Circuits guard
against overheating.
•••••
Power Control
The McIntosh Power Control Circuit allows for remote
turn-on of the MC402 Power Amplifier from a McIntosh
Audio/Video Control Center or Preamplifier. If any addi-
tional McIntosh Power Amplifiers are part of the system a
delayed Power Control Output Trigger is available. This
delayed trigger reduces the strain on the house’s electrical
wiring and protection devices.
Now you can take advantage of traditional McIntosh stan-
dards of excellence in the MC402 Power Amplifier. Two
400 watt high current output channels will drive any high
quality Loudspeaker system to its ultimate performance.
The MC402 reproduction is sonically transparent and abso-
lutely accurate. The McIntosh Sound is “The Sound of the
Music Itself.”
•••••
Balanced and Unbalanced Inputs
Balanced connections guard against induced noise and al-
low long cable runs without compromising sound quality.
•••••
Illuminated Power Meters
The Illuminated Power Output Watt Meters on the MC402
are peak responding, and indicate the true power output of
the amplifier. The Peak Watt Hold Mode allows the meters
to temporarily stay at the highest power output and then
slowly decay. The Front Panel Meter Illumination may be
switched Off at any time.
•••••
Fiber Optic Solid State Front Panel Illumination
The Illumination of the Front Panel is accomplished by the
combination of custom designed Fiber Optic Light Diffus-
ers and Light Emitting Diodes (LEDs). This provides even
Front Panel Illumination, together with the extremely long
life LEDs.
•••••
Glass Front Panel and Super Mirror Chassis Finish
The famous McIntosh Illuminated Glass Front Panel with a
three dimensional look and the Stainless Steel Chassis with
Super Mirror Finish ensures the pristine beauty of the
MC402 will be retained for many years.
