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