"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.
