Marantz MM7055 5 Channel Power Amplifier offers multi-channel rich, immersive and powerful, 5 x 140 Watts at 8Ω, sound. And features advance Amplifier Technology including Current Feedback Circuitry, Linear Drive Power Supply and High-Performance power supply to deliver controlled and precise sound.

Marantz MM7055 Multichannel Main Amplifier is the five-channel option in this year's extended line-up of main amplifiers. Based on the technology used in the MM8003 and using the exact same chassis, it delivers a thumping 140 Watts RMS into 8 ohms to each of the channels, while the ultra-wide bandwidth current feedback technology easily handles the highest SACD frequencies - this also makes it ideal for the high definition DTS Master Audio and Dolby TrueHD formats too. The result? Totally precise tonal and image balance, speed and dynamics. And on top of all that, you also get XLR audio inputs, DC triggers and a Marantz control bus system for remote on/off. This is power and convenience to take your breath away.

Current feedback discrete power amp

This is equipped with a current feedback power amp that uses the complementary push-pull circuit used in the SM-11S1 Marantz Hi-Fi power amp. This amp provides increased operating stability, and high-speed, wide-ranging high-density playback.

The current/voltage conversion amplification section in the latter part of the power amp is equipped with a Wilson current mirror circuit that amplifies to the high sound range with low distortion.

Improved instant power supply capability

The final stage of the power amp is equipped with the same LAPT (high-efficiency power transistor) that is installed in the SM-11S1 Marantz Hi-Fi power amp, providing improved instant power supply capability.

The power section is equipped with a large-sized transformer. As one of the essential parts of the power section, this unit is equipped with Marantz original 33,000 μF / 71 V×2 (MM7055), and 15,000 μF / 71 V×2 (MM7025) block condensers, which have been repeatedly tested for sound quality. These improvements to the power supply capability provide a powerful, presence-filled sound.

Other Functions

Equipped with IR flash input that supports custom installations, and DC trigger input and output terminals.

High sound quality design based on pure surround philosophy

Equipped with a chimney-shaped heat sink to efficiently process the heat emitted from each channel amp and exceptionally quiet cooling fans. A high-sensitivity temperature sensor IC is used to control the cooling fans, adjusting the rotation speed to match the amount of heat generated by the amp. These components provide the sound quality and low-noise you would expect at a high-end theatre. In addition, this unit is designed for superb quality sound and is equipped with high-quality components such as a high-end audio condenser and film condenser throughout.

BALANCED/UNBALANCED selecting function

Depending on the desired use, input for each channel can be selected between BALANCED input and UNBALANCED input.

Remote Power Control

This unit is equipped with a remote power control function. When a Marantz AV Pre-tuner AV8003 or AV7005 is connected to this unit, this unit’s power can be switched ON/OFF together with the AV8003 or AV7005 power supply. Connection to the AV8003 or AV7005 is a ground floating connection that prevents negative influences on sound quality as far as possible.
