Marantz MM8077 7-Channel Power Amplifier

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.

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.

Featuring Marantz’s 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 a 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. 

For maximum connectivity, the MM8077 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.

The MM8077 features a DC trigger input for external power on/off control, 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.
