Marantz MM7055 Multi Channel Power Amplifier
5-CHANNEL POWER AMPLIFIER
5 channels of pure power
The MM7055 is expertly crafted to meet all your high powered needs. It's designed to deliver consistent and precise power wherever and however you need it.
The MM7055 is the five-channel option in our extended line-up of power amplifiers. 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. There's 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 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 theater system, whether based on a moderately powered receiver or a surround sound processor.
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.
