About: This is McIntosh’s one of best Amplifiers built with more than enough power to drive almost any speaker system with very few hours of use.
The MC-205 amplifier teams a very low distortion, with a potent 200 Watt per channel x 5 channels autoformer-coupled amplifier for a total of conservative 1000 Watts of audio power.
■ The MC205 delivers all the explosive dynamics that high-performance home theater systems require by delivering 200 watts of power to each of the 5 individual channels commonly used in home theaters.
■ Massively over built amplifier design does not require cooling fans so the most subtle film soundtracks are not masked by common amplifier fan noise.
■ Precision McIntosh power watt meters allow monitoring of the primary front sound stage while clever engineering matches the output of MC205 with all speaker types.
■ Features many notable McIntosh technologies including Power Guard® to prevent harsh sounding clipping that could damage your speakers as well as Sentry Monitor™ that shuts down the unit if current exceeds safe operating level.
■ May be combined with a stereo amplifier to complete a five-channel home theater plus two channel remote zone.
Power Output: Minimum sine wave continuous average power output per channel, all channels operating is: 200 Watts into a 4 Ohm or 8 Ohm load.
Output Load Impedance: 8 and 4 Ohms
Rated Power Band: 20Hz to 20kHz
Total Harmonic Distortion: 0.005% maximum harmonic distortion at any power level from 250 milliwatts to rated power, 20Hz to 20kHz.
Overall Dimensions (W x H x D): 17-1/2" (44.45cm) x 9-7/16" (23.97cm) including feet x 21" (53.3cm) including the front panel and cables
Weight: 81 lbs. (44.2kg) net 114 lbs. (51.8kg) in shipping carton
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.
Exclusive McIntosh Power Assurance System: A collection of technologies that enhance performance and reliability while protecting the amplifier and loudspeakers.
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.

The MC205 is a powerful amplifier conservatively rated 200 watts for each of the five channels. It delivers all the explosive dynamics that high-performance home theater systems require by delivering 200 watts of power to each of the 5 individual channels generally used in many home theaters. The exclusive Dynamic Power Manager® (DPM) technology from McIntosh enables it to deliver full power into 4 and 8 ohm speakers - making the MC205 a perfect choice for a wide variety of home theater speakers. It can also be used as a two zone amplifier with three channels operating one zone and the remaining two channels assigned to a second zone.
The MC205 does not need cooling fans so even the most subtle soundtracks are not masked by fan noise. It features many notable technologies including Power Guard® and Sentry Monitor™. Inputs for balanced and unbalanced cables are available to provide flexibility in connecting the MC205 to your system or home theater processor. A bank of three blue watt meters provides instant recognition of power output of the front channels (the meters may be switched off if they conflict with the television or movie screen).
The MC205 could be combined with a stereo amplifier to complete a five channel home theater plus two channel remote zone. The classic black glass front panel and custom machined end caps allow the MC205 to blend in easily with any surrounding.

The MC-205 power amplifier utilizes a 2-stage differential-balanced voltage amplifier coupled to a push-pull current amplifier and Output Autoformer. This topology exhibits extremely low noise and distortion along with high current capability and is designed to drive a wide range of loudspeakers to sound their very best. The output Autoformer enables the MC-205 to respond with full rated power and low distortion regardless of the load connected and delivers 200 watts per channel into 8, 4 or 2 ohms.
