The MM7025 is expertly crafted to meet all your high powered needs and drive even the most demanding speakers by designing the entire unit to deliver consistent and precise power wherever and however you need it.
- 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.
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 dialogue 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.
