Key Benefits

Power For Your System

The MM7055 power amplifier produces 140 watts of high current output from each of its five channels.

The Many Faces Of Excellence

In practical terms, the MM7055 is ideal for a “5.1” home theater system, whether based on a moderately powered receiver or a surround sound processor.

More Marantz Power

A massive power supply includes a multiple-secondary EI-core transformer and over 65,000 µF of custom-designed energy storage capacity.

Cool Machine, Warm Sounds

Physically, the MM7055’s output stages mount on an extruded aluminum “thermal tunnel” for efficient heat dissipation.

Flexible Connections

Balanced inputs and single-ended RCA inputs are both supported, and you can choose either type of input for each channel, individually, for easy and flexible connectivity. Audiophile grade, gold-plated four-way binding post speaker terminals insure tight connections to your choice of speaker wire.
