Rated at 150 watts per channel into 8 ohms (180 watts per channel into 6 ohms), the Marantz MM8077 7-channel power amplifier will provide your system with extraordinary power and detail for all your entertainment options. The power supply features a high current toroidal power transformer along with high power (71WVDC) filter capacitors 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ﾒs high resolution audio formats.

Cool and quiet
The output devices are mounted on a 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ﾒs running, itﾒs designed to be whisper quiet.

High-performance connectors
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.

A DC trigger input allows 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.

A classy chassis
The copper-plated chassis provides isolation from extraneous noise, and utilizes 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.
