The MC207 can easily drive 4 ohm speakers, with their
high current demand. Additionally, the MC207 can be used
with 8 ohm speakers, and deliver equal power. McIntosh’s
new DPM
TM
design enables it to run on higher voltage rails
when connected to less current-hungry 8 ohm speakers and
still deliver 200 watts. The power penalty usually paid with
8 ohm speakers on high current amplifiers does not exist
with this new design.
The high efficiency circuit design of the MC207 con-
tributes to
low oper-
ating tem-
peratures.

Protection Circuits
The MC207 incorporates its version of the McIntosh Sen-
try Monitor out-
put transistor
protection cir-
cuit. Refer to
figure 17. There
is absolutely no
compromise in
sonic perfor-
mance with this
circuit, and it
ensures safe op-
eration of the
amplifier under
even the most
extreme operat-
ing conditions.
The different
types of protec-
tion circuits in-
corporated in
the MC207 in-
sure a long and
safe operating
life.
The MC207
also includes the
unique patented
McIntosh Power
Guard circuit.
Power Guard
eliminates the
possibility of
ever overdriving
the amplifier
into clipping.
Refer to figures
18, 19 and 20.
An overdriven
amplifier can
produce both
audible and in-
audible distor-
tion levels ex-
ceeding 40%.
The audible dis-
tortion is un-
pleasant to hear,
