Dynamic Power Manager

“ the muscle power needed for home theater

combined with the

musicality

that McIntosh is known for”

With so much power in the MC207, you might not expect to see super low
noise (112dB down), almost immeasurable distortion (0.005%), and cool
operation. McIntosh has applied over 55 years of power amplifier design
and build experience into the MC207.

Dynamic Power Manager, a new McIntosh innovation, ensures that every­one gets all the power they paid for. Unlike other high-current amplifiers,
the MC207 delivers full power of 200 x 7 channels into either 4 or 8 ohm
loudspeakers. The meters even recalibrate to the speaker load!

The McIntosh inverted, polished stainless steel, chassis design places heat
producing components above the chassis for cooler operation and keeps
sensitive circuits below in a shielded environment.

Modular Construction is used throughout the MC207. This internal construction
is a lesson in clean, computer-aided mechanical and electrical engineering.

The Exclusive McIntosh Power Assurance System built into the MC207
unites several of our patented and unique features that enhance performance
and reliability while protecting the amplifier and loudspeakers.

Seven Channel

Power Amplifier

DYNAMIC POWER MANAGER

TM

A new “smart” circuit

optimizes amplifier

characteristics for

the impedance of the

speakers connected

automatically, always

delivering the full power

the amplifier is capable of.

SENTRY MONITOR

Prevents amplifier damage

in case of accidental short

circuits in the speaker wires,

without the use of fuses.

OUTPUT WATTMETERS

Staying within the power

limits of speakers is

easy with the McIntosh

illuminated, peak-

reading meters.

POWER GUARD

Prevents overdriving the

amplifier (clipping) by

turning the volume down,

and back up before

overload happens. This

can all take place in

1/1000 of a second, using

a photo-optic circuit.

This is protection

at the speed of light.

PANEL DESIGN

McIntosh glass panels do

more than look great. Long-

life fiber-optic back-lighting

makes operation easy in low

light. Applying the lettering

to the rear of the panel

preserves both beauty and

highest resale value…

a McIntosh hallmark feature.
