Marantz MM7025 2-Channel Stereo Power Amplifier

MM7025

2 channel power amplifier with 140W

Focused power.

Featuring a classic industrial design, high-capacity power supply, and assured system compatibility, the Marantz MM7025 delivers consistent and precise power wherever and however you need it.

MM7025 answers many needs for both two-channel devotees and home theatre enthusiasts alike. It produces 140 watts of full-bandwidth, very low distortion power per channel, so it can precisely control demanding speakers in large rooms or deliver subtle nuance in smaller acoustic environments.

The MM7025’s advanced technology serves all your listening needs. Current feedback circuits, originally developed for Marantz Reference Series amps, insure the purest sonic reproduction regardless of source. In the final amplification stage, specially selected LAPT Hyper-Power output transistors, also borrowed from the Reference Series, deliver fortissimo and pianissimo pas- sages with equal aplomb.

The MM7025’s heavy duty, gold-plated, four-way binding posts accept virtually any choice of loudspeaker cable. The amplifier is less than 14” deep from front panel to rear speaker terminals. This lets you place the MM7025 almost anywhere – in a cabinet or on a shelf. Selectable single-ended and balanced inputs assure easy connectivity in any system.

First Impressions

If you’re impressed by elegantly restrained industrial design, the MM7025 is guaranteed to make a lasting – and very positive – impression.

 

Getting Connected

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

 

Your System, Your Way

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.

 

The Power Supply
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.

 

Output Devices
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".

 

Marantz Sound Quality
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.

 

Remote Control, Too
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.
