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 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.

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.

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.
