You are Mclntosh protected
six ways with the new
Mclntosh amplifiers.
PROTECTION
1. The patented Mclntosh Sentry Monitoring circuit
constantly monitors the output signal. At signal
levels up to rated output this circuit has high im-
pedance and has no effect upon the output. If the
power output exceeds design maximum, the Sentry
Monitoring circuit operates to limit the signal to the
output transistors. In the event of a short circuit
across the amplifier output or severe impedance
mismatch the Sentry Monitoring circuit will protect
the output transistors from failure. Both positive and
negative halves of the output signal are monitored
independently.
PROTECTION
2. Should the temperature of the heat sinks rise
above normal through restricted ventilation or other
causes, the AC Power is disconnected by an
automatic heat sensing relay. The AC power will be
restored when the temperature returns to normal.
PROTECTION
3. Any loudspeaker damaging DC component in the
output circuit, from whatever cause, is shunted to
ground through the Mclntosh autotransformer. You
and your speakers are protected completely from
this kind of amplifier failure.
PROTECTION
4. Mclntosh gives you a money back guarantee of
performance. Your Mclntosh instrument must be
capable of meeting its published performance limits
or you get your money back. No other manufacturer
offers you this money back guarantee of perfor-
mance.
PROTECTION
5. The Mclntosh 3 Year Service Contract protects
you from the cost of repair for three full years
because Mclntosh will provide the service materials
and labor needed to return the measured perfor-
mance to the original performance limits. The SER-
VICE CONTRACT does not cover any shipping costs
to and from the authorized service agency or the fac-
tory.
PROTECTION
6. The Automatic Test System provides positive pro-
tection and extends the long trouble free life of an
amplifier. Each time the amplifier is turned on seven
tests measure and verify accurate performance.
Automatic Test System protects by verifying circuit
readiness before operation starts. Each time a test
is verified a numeric indicator turns on to indicate
the test being performed. If in the test countdown an
unacceptable voltage is encountered, the numeric
designation locks to isolate the faulty circuit.
