MM7055 5-channel Power Amplifier

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 µF 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 MM7055’s 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 amplifier’s 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 14˝” 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. From its sculptured front panel to its high quality loudspeaker binding-post s, the MM7055 five channel power amplifier brings Marantz sound quality to virtually any music or home theater system. Using technologies originally developed for the exclusive Marantz Reference Series, this flexible amplifier boasts many possible uses, all united by the singular quest for perfection that has long distinguished Marantz.
