140W 5-Channel Current Feedback Power Amplifier
5ch Power Amplifier
The 5 channel MM7055 is expertly crafted to meet all your high power needs with 140W per channel and drives even the most demanding surround speaker setups. The entire unit is designed to deliver consistent and precise power whenever needed.
5 channels of pure power
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.
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."
