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

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.

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

Featuring 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.

The output devices are mounted on 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.

For maximum connectivity, it features both unbalanced (RCA) and balanced (XLR) inputs, and each amp channel can be configured to use your choice of input connector. The loudspeaker terminals feature audiophile-grade construction, and are gold-plated for maximum signal transfer, and they can easily handle a wide range of audiophile speaker cable connectors.

A DC trigger input for external power on/off control is provided, and there’s also dual RC-5 remote control in/out jacks for connection to a compatible Marantz A/V pre-amp/processor.

The copper-plated chassis provides isolation from extraneous noise, and features a multi-layer reinforced bottom panel assembly for maximum rigidity along with triple-layer top cover. Elegantly finished in anodized black satin, the MM8077 features the classic Marantz ringed porthole display with a blue illumination accent that includes a display on/off function.
