7 Channel Power Amplifier from Marantz

Designed for the ultimate music and movie surround sound experience, the MM8077 7-channel power amplifier is equipped with the same amplifier technologies that are incorporated in our reference class hi-fi amplifiers, including our unique current feedback discrete power amplifier stage design, which features a high slew rate that provides a wide bandwidth for the utmost enjoyment of todays high resolution audio formats.

All output stages feature identical topology for uniform high quality sound across all channels, and the MM8077 provides the option to choose between balanced (XLR) and unbalanced (RCA) inputs for each channel, for maximum system configuration flexibility.

High current, high bandwidth discrete power transistors can handle short term musical bursts with aplomb, even into difficult low impedance speaker loads.

Masterfully Built

MM8077 is built to deliver on its promise of high-performance power. It’s no-nonsense, yet elegant design ensures that every ounce of amplification is available whenever you require it.

Clean and Consistent Power

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

Sound Master Tuned

The Marantz Sound Master meticulously tuned MM8077 for amazing performance with careful parts selection to create the Most Musical Sound in your home.

Unique Current Feedback

Featuring Marantz's very own 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.
