Marantz MM8077 7ch Power Amplifier Black

7-channel Power Amp Packed with Proprietary Marantz Audio Technology

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 Marantz reference class hi-fi amplifiers, including the 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. At the heart of the MM8077 is Marantz high current power supply, which features 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.

High current, high bandwidth discrete power transistors can handle short term musical bursts with aplomb, even into difficult low impedance speaker loads. The MM8077 is rated at 150 watts per channel into 8 ohms for each of the 7 channels. For the ultimate home theater experience, you can pair the MM8077 with the MM7705 5-channel power amplifier, which lets you 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 the AV8801.
