McIntosh MC205 power amplifier, ex-demo, fully boxed, immaculate condition (£9000 New)
An incredible blend of power and versatility, the MC205 delivers all the explosive dynamics required by today’s demanding high-performance home theater systems. Dynamic Power Manager (DPM), an exclusive McIntosh technology, insures top performance at 8 and 4 ohms, enabling the MC205 to deliver 200 watts per channel into a wide variety of loudspeakers. The MC205 offers outstanding versatility, and can be used as a five-channel home theater amplifier, as well as a two zone amplifier with three channels in one zone and the remaining two channels assigned to a second zone.
POWER ASSURANCE SYSTEM
A collection of technologies that enhance performance and reliability while protecting the amplifier and loudspeakers.
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.
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.
Swift, accurate response reveals program peaks so staying within the power limits of your loudspeakers is easy.
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.
