Those considering a McIntosh system for the first time will find integrated amplifiers a comfortable place to start. In virtually every respect the MA6900 performs as well as McIntosh separates. The MA6900 incorporates premium McIntosh technologies- including autoformers, Power Assurance, and Silent Electronmagnetic Switching- as well as several features that facilitate system integration and expansion.
This massive stereo integrated amplifier
delivers 200 watts/channel. It boasts the classic McIntosh look of glass
front panel with two huge illuminated blue output meters. Convenience
features plus natural sound with no dynamic limitations - what more
could you ask? Power Guard Circuitry protects it from clipping, while
Sentry Monitor circuits protect it under extreme operating conditions.
And, of course, it boasts McIntosh's legendary quality.
MA6900 Integrated Amplifier Features
5 BAND EQUALIZER
Great for touching up an old recording, or
taming the acoustics of a problem room.
FLEXIBILITY
One set of balanced inputs, main
preamp-out/amp-in connection and two additional
switched preamp outputs are included. The
ability to drive speaker loads down to 2 Ohms
make this the perfect amplifier for driving
multiple pairs of speakers.
PHONO INPUT
The ultra-quiet McIntosh phono stage for moving
magnet cartridges is built-in. If desired, this
input may be changed to an “aux” high level
input in seconds.
GROW YOUR SYSTEM
With the addition of optional McIntosh sensors,
the amplifier and other McIntosh components can
be operated from additional rooms. Complete your
system with a McIntosh tuner and a McIntosh CD
changer.
