"the power you want and the flexibility
you need all combined in a single component"

Designed to deliver a continuous 200 Watts
per channel, the MA6900 also provides
selection and control of 6 input sources,
including one balanced input and selectable
moving-magnet phono stage. Loudness
compensation, 5-band equalizer, precision
trimmed volume control and two sets of
switched outputs add to the list of features
of this integrated amplifier.

Unique in the world of solid-state amplifiers,
the MA6900 utilizes an autoformer at the output
of each channel. The autoformer provides an
ideal match for all types of speakers,
regardless of their impedance, and allows the
MA6900 to always deliver all of its rated
200 Watts per channel. Whether your speakers
are 8, 4 or 2 ohms, the exclusive McIntosh
output autoformer ensures that you will always
get all of the power that you pay for.

The preamp section of the MA6900 utilizes
encapsulated switching, which reduces noise
to the vanishing point. Instead of taking
the music signal "for a ride"
through long wires and open connections
that can oxidize and become intermittent
with age, all input switching in the MA6900
is done using sealed electromagnetic
switches located close to the input jacks.
Filled with an inert gas, these
glass-encapsulated devices cannot oxidize
and never need cleaning.
