If you’re impressed by elegantly restrained industrial design, the MM7025 is guaranteed to make a lasting – and very positive – impression. The subtly curved aluminum/glass resin front panel adds a sophisticated touch that complements any décor.

Marantz® 2 Channel Power Amplifier

If you’re impressed by elegantly restrained industrial design, the MM7025 is guaranteed to make a lasting – and very positive – impression. The subtly curved aluminum/glass resin front panel adds a sophisticated touch that complements any décor.  The central porthole display reflects iconic Marantz designs of the past while it brings you an “at a glace” view of the amplifier’s operating status.

Both single-ended RCA and balanced XLR inputs assure system compatibility regardless of your preamplifier or processor.

For maximum flexibility, you can choose inputs independently for each channel.

The MM7025’s heavy duty, gold-plated, four-way binding posts accept virtually any choice of loudspeaker cable

The MM7025 encourages various system configurations.  Use one for dedicated two-channel listening, or use two to as zone amplifiers to power speakers in different rooms.  Adding a new pair of loudspeakers to an existing home theater? – Get the most from your investment by adding an MM7025 as well.  The exact configuration is up to you.  Sound quality isn’t – it’s Marantz regardless of how you use this power amplifier.

The MM7025’s advanced technology serves all your listening needs. Current feedback circuits, also used in Marantz’s Reference Series amps, insure the purest sonic reproduction regardless of source.  Another MM7025 virtue, and one directly traceable to its substantial current capability, is the control it establishes over difficult speakers to reproduce both dynamic musical peaks and whispered dialog without blemish.

As befits a Marantz amplifier, the high-capacity power supply begins with an oversized EI-core transformer feeding carefully chosen capacitors capable of storing 30,000 µF of energy.  This combination instantaneously delivers peak power to all amplifier stages for distortion-free reproduction of the most complex sources.

In the final amplification stage, specially selected LAPT Hyper-Power output transistors, originally selected for Reference Series use, deliver fortissimo and pianissimo passages with equal aplomb.  To make sure they’re always operating at ideal temperatures, these transistors are mounted on a forced-air “thermal tunnel.”

The MM7025 is less than 14” deep from front panel to rear speaker terminals. This lets you place the amplifier almost anywhere – in a cabinet or on a shelf.  A detachable AC cord makes placement easy, even when there’s little room and you can even rack mount it with the optional rack mount kit RMK8754MSP.

You’ll find rear panel connections for a “flasher” input that conveys On/Off commands from an infrared (IR) remote controller.  There’s a DC trigger input (and output) that lets you ”daisy chain” one or several MM7025s to turn on and off in synchronization with your preamplifer or surround processor.  If you’re going to use the MM7025 with legacy Marantz products, there are RC-5 connectors to give you a level of operating convenience you might not have thought possible.

Refined looks. Flexible connectivity. Superb sound quality. Convenient operation. Yes, these Marantz attributes come together in the MM7025 Stereo Power Amplifier.

It is, as are all Marantz products, devoted to one goal – satisfying your desire for an exceptional listening experience.

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 a

Marantz® 5 Channel Power Amplifier

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.

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.

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.

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.

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.

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 14½” 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.

The power supply features a high current toroidal power transformer along with high power (71WVDC) filter capacitors with a total 100,000µF capacitance to easily handle sharp short-term transient peaks.

Featuring our unique current feedback discrete power amp output stages that are identical for all channels, the MM8077 is equipped with multiple high current discrete power transistors that feature high slew rate and wide operating bandwidth to extract the most detail from today’s high resolution audio formats.

The output devices are mounted on our unique dual extruded aluminum alloy heat sink assembly, configured in a tunnel arrangement that provides both passive and active cooling. The massive heat sinks feature multiple ribbed fins that provide a large passive cooling area, and the assembly is book-ended with a whisper quiet fan that automatically kicks in to provide near silent active cooling when the soundtrack heats up. As the fan is mounted internally directly to the heat sinks, and not externally to the chassis cover as is often the case, even when it’s running, it’s designed to be whisper quiet.

For maximum connectivity, the MM8077 features both unbalanced (RCA) and balanced (XLR) inputs, and each amp channel can be configured to use your choice of input connector. The loudspeaker terminals feature audiophile-grade construction, and are gold-plated for maximum signal transfer, and they can easily handle a wide range of audiophile speaker cable connectors.

The copper-plated chassis provides isolation from extraneous noise, and features a multi-layer reinforced bottom panel assembly for maximum rigidity along with triple-layer top cover. Elegantly finished in anodized black satin, the MM8077 features the classic Marantz ringed porthole display with a blue illumination accent that includes a display on/off function.
