Ideal for your 5.1 home theater system
Marantz sound experts meticulously designed this unit to deliver precise power and accurate musicality.
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.
