Introduction
Power Output
The MC207 consists of seven Power Amplifier Channels,
each capable of 200 watts into 4 ohm or 8 ohm Loudspeak-
ers with less than 0.005% distortion.
Now you can take advantage of traditional McIntosh stan-
dards of excellence in the MC207 Power Amplifier. Seven
200 watt high current output channels will drive any high
quality Loudspeaker System to its ultimate performance.
The MC207 reproduction is sonically transparent and abso-
lutely accurate. The McIntosh Sound is “The Sound of the
Music Itself.”

Patented Power Guard
The patented McIntosh Power Guard Circuit prevents the
amplifier from being over driven into clipping, with its
harsh distorted sound that can also damage your valuable
Loudspeakers.
Dynamic Power Manager
TM
The MC207’s Dynamic Power Manager (DPM) circuitry
allows for the connection of either 4 ohm or 8 ohm Loud-
speakers, while at the same time delivering identical power
output. A peak output current of 25 amperes per channel
ensures that it will successfully drive high quality Loud-
speakers such as McIntosh for a truly exciting sound expe-
rience.
Balanced and Unbalanced Inputs
Balanced connections guard against induced noise and al-
low long cable runs without compromising sound quality.
Patented Sentry Monitor with Thermal Protection
McIntosh Sentry Monitor power output stage protection
circuits ensure the MC207 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 MC207 Power Amplifier from a McIntosh
A/V Control Center or Preamplifier for a single or dual
Zone System.
Illuminated Power Meters
The Illuminated Power Output Watt Meters on the MC207
are peak responding, and indicate the power output of the
Front Amplifier Channels. The 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 extra long life
LEDs.
Glass Front Panel and Super Mirror Chassis Finish
The famous McIntosh Illuminated Glass Front Panel and
the Stainless Steel Chassis with Super Mirror Finish ensure
the pristine beauty of the MC207 will be retained for many
years.
