McIntosh MC207 - Manual (Page 16)

McIntosh Laboratory, the company who introduced the
world’s first amplifier that could be called “High Fidelity”,
has done it again. The McIntosh engineering staff has cre-
ated a power amplifier without compromise, using the most
advanced McIntosh circuit design concepts.
A continuous average power output rating of 200 watts
and an output current of greater than 25 amperes per chan-
nel, makes this one of the most advanced and powerful am-
plifiers McIntosh has ever manufactured. The distortion
limits for the MC207 are no more than 0.005% at rated
power output for all frequencies from 20Hz to 20,000Hz.
Typical performance at mid frequencies is less than
0.002%. The true distortion readings on the MC207 are so
low, it takes special measuring techniques to make accurate
readings. The MC207 can deliver the best possible perfor-
mance from any type of high quality Loudspeaker System.
Technical Description
Inside View of the MC207
Creating an amplifier with this level of performance did
not come easily. Many months of design, testing and mea-
suring were required. Extensive controlled listening tests,
the ultimate form of measuring, were made before the final
design was accepted.
Design Philosophy
The design philosophy incorporated in the MC207 involved
several different techniques, all based on sound scientific
logic. Refer to figure 13. Every stage of voltage or current
amplification must be as linear as possible prior to the use
of negative feedback. McIntosh engineers know how to
properly design negative feedback circuits so they contrib-
ute to the extremely low distortion performance expected
from a McIntosh amplifier. The typical McIntosh owner
would never accept the approximately 100 times higher dis-
