EXCLUSIVE MCINTOSH
POWER ASSURANCE SYSTEM
A collection of technologies that enhance
performance and reliability while
protecting the amplifier and loudspeakers.
POWER GUARD®
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.
ELECTRONIC SWITCHING AND
BALANCED CONNECTIONS
The preamplifier uses Logic Circuits
controlling Electromagnetic Switches
on all inputs and operating functions
for reliable, noiseless distortion free
switching. There are two Balanced Inputs
for connection of source components and
a Balanced Preamplifier output for driving
an external Power Amplifier
POWER CONTROL AND
REMOTE CONTROL
The power control output connection
provides convenient Turn-On/Off of
McIntosh Source components. The
Data Ports together with the supplied
Remote Control provides control of
McIntosh Source components
connected to the MA6600.
WATTMETER
Swift, accurate response reveals program
peaks so staying within the power limits
of your loudspeakers is easy.
FOR THE CONSUMER’S
PROTECTION

customer satisfaction, “new” McIntosh
products may only be purchased over-the-
counter or delivered and installed by an
