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, including our 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 our 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 our 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 our AV8801.

Marantz Audio Advantages

• 150 W/ch (8 ohms), 180 W/ch (6 ohms) RMS Power (20 Hz - 20 kHz)
• Low impedance continuous drive capability
• Highest sound quality design based on pure surround philosophy
• Marantz reference-grade power supply filter capacitors and high speed, high current discrete power transistors
• Copper plated chassis
• Current feedback discrete power amplifier: The Marantz current feedback discrete power amplifier topology employs high current, wide bandwidth power transistors that feature high slew rate along with low impedance drive capability, for maximum operating bandwidth and solid perfor- mance with difficult speaker loads. The MM8077 is rated at 150 watts in 8 ohms for each of the 7 channels (continuous), and can deliver 180 watts into 6 ohms.
• High power, high current power supply featuring 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., which is especially helpful when driving difficult-to-drive lower impedance speakers.

Convenience & Control

• Porthole display with blue illumination accent
• Gold plated, high grade loudspeaker terminals L
• Low-power standby mode: For environmental and energy-saving consider- ations, power consumption during standby mode has been reduced to less than 0.4 W
• Auto-standby mode: The MM8077 automatically switches to standby mode when there has been no signal for 30 min- utes. This prevents power from being wasted whenever you forget to turn the power off.
• Flasher input
• DC trigger (In/Out)
• Remote control (In/Out)
