Marantz MM8077 - 7 Channel Power Amplifier

Marantz MM8077 Power Amplifier

The Marantz MM8077 is a high-current 7-channel Class A/B power amplifier built to bring real, effortless authority to a home theater or high-resolution music system. With 150 watts per channel and Marantz’s current feedback discrete amplification, it delivers clean, consistent power with the speed and control needed for dynamic movie soundtracks and detailed, full-range audio. A toroidal transformer and 100,000µF total filter capacitance provide the headroom to handle sudden transients and help maintain composure with more demanding speaker loads.

For flexible system building, each channel supports balanced (XLR) or unbalanced (RCA) inputs (selectable), and integration is easy with DC trigger in/out, D-Bus/RC-5 remote in/out, and a flasher input. Finished with a copper-plated chassis, gold-plated speaker terminals, and Marantz’s signature porthole display with blue illumination, the MM8077 is a premium power upgrade for anyone who wants higher impact, better separation, and more confident control across every channel. The Marantz MM8077 is part of ListenUp's Marantz Amplifiers Collection.

What It's Good At:

• Driving full surround systems with authority: 7 channels of robust Class A/B power for immersive theaters
• Staying clean during big dynamic swings: toroidal supply and massive capacitance for transient headroom
• Sound that’s detailed yet musical: Marantz Sound Master tuning with current feedback topology
• Handling tougher speaker loads: designed for low-impedance continuous drive capability
• Flexible integration: selectable XLR/RCA per channel plus triggers and control connections
• Rack/system friendliness: auto-standby, low-power standby, and remote power on/off compatibility

Marantz MM8077 Q&A:

What kind of system is the Marantz MM8077 best for?

It’s ideal for home theaters that need high-quality, high-current amplification across up to seven speakers, delivering stronger dynamics and cleaner separation than most receiver amps.

How much power does the MM8077 deliver per channel?

It’s rated at 150W per channel into 8 ohms (20Hz–20kHz, 0.08% THD, two channels driven) and 180W per channel into 6 ohms under the same rating conditions.

Does the MM8077 support balanced XLR connections?

Yes. Each channel supports balanced (XLR) or unbalanced (RCA) inputs, selectable to match your preamp/processor and system layout.

Is this amplifier Class D or Class A/B?

The MM8077 is a Class A/B amplifier designed for a smooth, powerful presentation with excellent control and bandwidth.

Can the MM8077 turn on and off automatically with my system?

Yes. It includes DC trigger in/out and supports remote power on/off control compatibility with select Marantz preamps, plus an auto-standby function after 30 minutes of no signal.

What speakers can it drive?

It’s designed with a high-current power supply and low-impedance drive capability to better handle more demanding speakers, especially when your system needs strong multi-channel performance.

What makes the MM8077 sound “Marantz”?

It uses current feedback discrete output stages, careful parts selection, and Sound Master tuning to maintain detail, musicality, and consistent performance across all seven channels.

What control connections are included for custom installs?

You get DC trigger (1 in/1 out), D-Bus/RC-5 (1 in/1 out), and a flasher input, making it easy to integrate into a control ecosystem.
