Description

Meet the MM7055

5-Channel Power Amplifier from Marantz

The MM7055 is a refined amplifier with ample power for the most demanding home theater setups and delivers exceptional musical clarity.  

Based on the technology used in the MM8003 and using the exact same chassis, it delivers a thumping 140W RMS into 8 ohm to each of the channels, while the ultra-wide bandwidth current feedback technology easily handles the highest SACD frequencies this also makes it ideal for the high definition DTS Master Audio and Dolby TrueHD formats too.

The result?

Totally precise tonal and image balance, speed and dynamics. And on top of all that, you also get XLR audio inputs, DC triggers and a Marantz control bus system for remote on/off. Theres even a stylish new display screen showing the actual output power. This is power and convenience to take your breath away. 

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.
