l e g e n d a r y

power amplifier

With a total of 1000 watts of power, the MC205 delivers all the explosive dynamics that
high-performance home theater systems require. What’s more, by incorporating McIntosh’s
Dynamic Power Management (DPM)™ circuit topology, the MC205 delivers full power into a
wide variety of loudspeaker types.

Unlike other high-current designs, the MC205 delivers the same 200 watts per channel
into both 4-Ohm and 8-Ohm loudspeakers. The Dynamic Power Manager automatically
controls and optimizes the power supply’s voltage and current balance delivering higher
voltage that 8-Ohm speakers require, and automatically adjusting for current-hungry
4-Ohm speakers.

Versatility reigns with the MC205. Aside from a 5-channel home theater amplifier the
MC205 can also be used as a two zone amplifier with three channels in one zone and the
remaining two channels assigned to a second zone.

McIntosh amplifiers, whether two-channel or multi-channel designs, are known for smooth,
non-fatiguing sound, and the MC205 is no exception. Distortion remains below 0.005%
across the entire 20-20,000 audio band at full power. Noise levels are vanishingly low, and
five balanced (XLR) input connections help prevent noise pickup in connecting cables
from degrading the amplifier’s low noise advantages.

A collection of technologies that
enhance performance and reliability
while protecting the amplifier and
loudspeakers.

200 Watts into 4-Ohm or 8-Ohm loads minimum
sine wave continuous average power output per
channel with all channels operating. The output
RMS voltage is 40.0 across 8-Ohms and 28.3
across 4-Ohms.

OUTPUT LOAD IMPEDANCE

8 or 4 Ohms

RATED POWER BAND

20Hz to 20kHz

TOTAL HARMONIC DISTORTION

level from 250 milliwatts to rated power per channel
from 20Hz to 20kHz, all channels operating.

DYNAMIC HEADROOM

1.7dB

FREQUENCY RESPONSE

+0, -0.25dB from 20Hz to 20kHz
+0, -3.0dB from 10Hz to 100kHz

INPUT SENSITIVITY

8 Ohms: 1.4 volt unbalanced; 2.8 volts balanced
4 Ohms: 1 volt unbalanced; 2 volts balanced

SIGNAL-TO-NOISE RATIO (A-WEIGHTED)

112dB below rated output

INTERMODULATION DISTORTION

Maximum intermodulation distortion if
instantaneous peak output per channel does
not exceed twice the rated output, for any
combination of frequencies from 20Hz to
20kHz, with all channels operating is 0.005%
for 4 or 8 Ohm loads.

INPUT IMPEDANCE

10,000 Ohms unbalanced 20,000 Ohms balanced

WIDE BAND DAMPING FACTOR

8 Ohms; grate than 140, 4 Ohms; greater than 70

DIMENSIONS (INCLUDING CLEARANCE
FOR CONNECTORS) H X W X D

9-7/16” (24cm) x 17-1/2” (44.5cm) x 21” (53.3cm)

WEIGHT

81 lbs. (44.1 kg) net,
114 lbs. (51.8 kg) in shipping carton

POWER GUARD

A waveform comparison circuit
continuously monitors both input and
output signals. Power Guard dynamically
adjusts the input level to avoid clipping
while preventing harsh sounding
distortion.

SENTRY MONITOR

Fuse-less short-circuit protection
circuit disengages the output stage
before current exceeds safe operating
level – resets automatically.

DYNAMIC POWER MANAGER
(DPM)™

By matching the characteristics of the
output stage to 4 or 8 Ohm loudspeakers
DPM insures the most efficient power
transfer, reduces distortion, and promotes
cool operation; with DPM you get all the
power you paid for.

WATTMETER

Swift, accurate response reveals program
peaks so staying within the power limits
of your loudspeakers is easy.
