MM8077

150W 7-CHANNEL CURRENT FEEDBACK POWER AMPLIFIER CIRCUIT FOR SUPERIOR SOUND

The MM8077 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.

Key Features

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.

Ultimate Powerhouse

Designed for the ultimate music and movie surround sound experience, the Marantz MM8077 7-channel power amplifier delivers power and detail, and is rated at 150 watts per channel into 8 ohms, and 180 watts per channel into 6 ohms.

Power The Most Demanding Of Systems

Toroidal Transformer Power Supply

Featuring Our Unique Current Feedback

Featuring our 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.

Masterfully Built

The output devices are mounted on our unique dual extruded aluminum alloy heat sink assembly, configured in a tunnel arrangement that provides both passive and active cooling. The massive heat sinks feature multiple ribbed fins that provide a large passive cooling area, and the assembly is book-ended with a whisper quiet fan that automatically kicks in to provide near silent active cooling when the soundtrack heats up. As the fan is mounted internally directly to the heat sinks, and not externally to the chassis cover as is often the case, even when it’s running, it’s designed to be whisper quiet.
