Product Information

MM7055 5-Channel Home Theater Amplifier

 

MM7055 Features:

Power For Your System

  • The MM7055 power amplifier produces 140 watts of high current output from each of its five channels.  This is real world power, too, measured across the full audio bandwidth (20 Hz 20 kHz) at 8 ohms with 0.08% Total Harmonic Distortion.  Among other attributes, this means the MM7055 is capable of long-term power delivery into low impedance speakers.

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.  You can use it to power speakers in different areas of your home; stereo reproduction in two rooms plus a mono channel for secondary areas such as a den or kitchen.  For more complex home theater systems, the MM7055 pairs with one or several MM7025s to help create a totally immersive 7.1 or 9.1 audio experience.

Inside The MM7055

  • A massive power supply includes a multiple-secondary EI-core transformer and over 65,000 F of custom-designed energy storage capacity.  Critical circuit components from many world-class suppliers were chosen only after extensive listening tests.  Among these, the LAPT Hyper Power output devices were first used in Reference Series components.  Current feedback topology insures astounding accuracy and control under high-drive conditions.

A Temperature-Controlled Environment

  • Physically, the MM7055s output stages mount on an extruded aluminum thermal tunnel for efficient heat dissipation.  With temperature-sensing forced air cooling, this configuration assures cool operating temperatures for long-term reliability, even when making full use of the amplifiers substantial output capabilities.

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.

Custom Touches

  • The MM7055 includes input and output jacks for DC trigger pulses as well as RC-5 jacks for total remote control convenience, even with legacy Marantz products.
  • The chassis itself is heavy gauge steel for maximum isolation from external vibration as well as electromagnetic and radio frequency interference.  And chassis depth is less than 1412 so the MM7055 will fit quite nicely on a shelf, in a cabinet, or in a conventional system rack with the optional rack mount kit RMK8003MM.
  • Power.  Functionality.  Dependability.  And classic looks.  The MM7055 is, simply speaking, a Marantz.

A must have
Best purchase ever must have for music quality enthusiast. Having a power amp allowed me to also add in professional equalizer to my SR 5011 receiver. Provided power to drive the surround speakers to turn up the movies and music experience to another level which was unachievable with the SR 5011 receiver alone

Issues with the MM7055
It is in reliable. I have had to replace or repair the 3 times Over my 5 year ownership lifespan. I experienced my 4th failure in august. Even though it was still under Warrentee, I decided to trash it and move to another brand.

Great Marantz Sound
Paired with the Marantz AV7705, this amplifier performs admirably. I am a fan of the Marantz sound and this pair does not disappoint.

Great amplifier dont be lured.
very clean and transparent amplifier. I use 2 of these in my current setup. They replaced emotiva xpa-5 gen 2 amplifiers. I currently use them both for my front height, surround and atmos speakers but would not be afraid to use them on the mains. They are dynamic and have plenty of headroom for transients. I have had them for 4 years now and will be upgrading my AV7702 this year with the AV7705 or 7706. I will not be changing amplifiers. I have used everything from pro QSC & Crown to Hafler and Emotiva. Do not get lured into the emotiva game. When they fail it will cost you 350 dollars flat rate to repair along with the 150 dollars to ship it to them. That food deal expires very quickly for something that should have lasted for 20 years as I expect the marantz will.

Sound quality and performance.
Quality and performance, I have never had a problem with this unit. I have it paired with a Marantz AV7702 and I use them for audio only the sound quality is excellent. It works great as a multi zone system. I had a Carver system for years and the difference in the sound quality was apparent the first time I listened to this unit. I love it!

AV Pre Tuner loaded with features
I purchased my AV7701 AV Pre Tuner and MM7705 5 channel power amplifier to upgrade an existing system. I was intrigued by the use of balanced connections between the Pre Tuner and power amplifier. Other features of interest to me were the built-in phono pre-amp and the Internet Radio capability. I was pleased to find that the FM Tuner had HD capability, but the tuner sensitivity (ability to pick up stations 60+ miles away, even though I am using a "large" Winegard FM antenna is not as good as expected. See "cons" for reliability comments.
