Marantz MM7055 Power-Amp

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

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.

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

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

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.
