Key info

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.


  • 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.
