EXCLUSIVE MCINTOSH
POWER ASSURANCE SYSTEM
A collection of technologies that enhance
performance and reliability while
protecting the amplifier and loudspeakers.
SENTRY MONITOR ®
TUBE PROTECTION
Fuse-less short-circuit protection
circuit disengages the output stage
before current exceeds safe operating
level -“ resets automatically.
UNITY COUPLED
OUTPUT CIRCUIT ®
Output power is taken from both the
plate and cathode of the output tubes.
Conventional designs only take output
from the latter. This allows ½ the turns
ratio, or ¼ the impedance transformation
of conventional designs. The result is much
lower distortion, wider bandwidth and
increased loudspeaker damping factor.
WATTMETER
Swift, accurate response reveals program
peaks so staying within the power limits
of your loudspeakers is easy.
FOR THE CONSUMERS
PROTECTION
In order to ensure the highest level of
customer satisfaction, new McIntosh
products may only be purchased over-the-
counter or delivered and installed by an
Authorized McIntosh Dealer.
McIntosh products that are purchased
over the Internet, by phone or mail
order are presumed to be used and do
not qualify for any McIntosh Warranty.
McIntosh does not warrant, in any
way, products that are purchased from
anyone who is not an Authorized Dealer
or products that have had their serial
number altered or defaced.
