Marantz MM7025

The Marantz MM7025 Stereo Power Amplifier answers many needs for both two-channel devotees and home theater 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 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. This is Marantz quality at its best.

Description

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.
