This amplifier uses a chimney-shaped heat sink to dissipate heat efficiently. Moreover, it includes quiet cooling fans controlled by a high-sensitivity temperature sensor. The fans adjust their speed automatically to match the amp’s heat output.
MM8077
Marantz MM8077 - 7 Channel Power Amplifier
The Marantz MM8077 - 7 Channel Power Amplifier brings powerful and clear multi-channel sound to your home theatre. It uses a discrete amplifier design, so the audio remains strong and detailed. Each channel delivers up to 150W at 8 ohms and 180W at 6 ohms, which means you get balanced sound even at high volumes.
In addition, the MM8077 offers both balanced and unbalanced inputs, making it easy to connect with many pre-amplifiers and processors. Because of this, it works well with stereo, 5-channel, or 7-channel systems, and it can also be added to larger 11-channel setups for full surround sound.
Furthermore, this amplifier uses Marantz’s current feedback design, the same technology found in their premium SM-11S1 Hi-Fi amplifier. As a result, it gives better stability, faster response, and more detailed playback across all frequencies.
Finally, the Wilson current mirror circuit improves high-frequency response and keeps distortion very low. With these features, the Marantz MM8077 - 7 Channel Power Amplifier ensures smooth, accurate, and powerful sound for movies, music, and gaming.
Large Toroidal Power Transformer – Marantz MM8077 - 7 Channel
The MM8077 includes a high-power, high-current supply with a massive toroidal power transformer. Therefore, it easily handles short-term power peaks. The amplifier also features high-capacity 100,000µF supply capacitors. Together, they deliver short bursts of extra power when driving demanding, low-impedance speakers.
High-Quality Design – Marantz MM8077 - 7 Channel
Balanced and Unbalanced Inputs - Marantz MM8077 - 7 Channel
Each channel provides both balanced and unbalanced inputs. As a result, installation is flexible, and compatibility with different systems is maximized.
Custom Installation-Ready
The MM8077 supports professional integration with an IR flash input, DC trigger input, and output terminals.
Remote Power Control
When paired with a Marantz AV8801 or AV7701 pre-amplifier, the MM8077 links power on/off functions directly. This ensures easy and synchronized control.
Energy-Saving Features - Marantz MM8077 - 7 Channel
Additionally, the MM8077 is eco-friendly. Its low-power standby mode reduces consumption to less than 0.4 W. Furthermore, auto-standby activates after 30 minutes of no signal, preventing wasted energy.
