Designed for the ultimate music and movie surround sound experience, the MM8077 7-channel power amplifier is equipped with the same amplifier technologies that are incorporated in our reference class hi-fi amplifiers. At the heart of the MM8077 is a high current power supply featuring a massive toroidal power transformer that provides substantial headroom for dynamic peaks along with the ability to handle lower impedance speaker loads. All output stages feature identical topology for uniform high quality sound across all channels, and the MM8077 provides the option to choose between balanced (XLR) and unbalanced (RCA) inputs for each channel, for maximum system configuration flexibility. The MM8077 is rated at 150 watts per channel into 8 ohms for each of the 7 channels. For the ultimate theater experience, you can pair the MM8077 with the MM7705 5-channel power amplifier, which lets your customers enjoy thrilling 11-channel surround sound with the latest multi-channel audio formats, such as DTS Neo:X. For easy control, the MM8077 features remote power on/off control compatibility with select Marantz A/V pre-amplifiers, such as our AV8801.
Power the Most Demanding Systems
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.
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 a unique dual extruded aluminum alloy heat sink assembly, configured in a tunnel arrangement that provides both passive and active cooling. The 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.
Audiophile-grade Construction
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.
Maximum Connectivity
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.
Maximum Rigidity
The copper-plated chassis provides isolation from extraneous noise and features a multi-layer reinforced bottom panel assembly for maximum rigidity along with a triple-layer top cover.
