Power For Your System
The MM7055 power amplifier produces 140 watts per channel (8-ohm, 20Hz – 20kHz, 0.08% THD, 2ch. drive) 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 theatre system, whether based on a moderately powered receiver or a surround sound processor. Two or more can be used to build an advanced system. A combination with MM7025 or MM8077 is possible.
-
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.
"The MM7055 offers excellent value for the money. "
"I do feel that it presents a compelling value to audiophiles who look at more than just rated power when buying an amplifier."
