MARANTZ MM8077

7-Channel Power Amplifier

The MM8077 is a seven-channel power amplifier designed to deliver extraordinary power and high-resolution sound reproduction, perfect for an immersive and precise home theater experience. Built to ensure high performance, the MM8077 stands out with its elegant and functional design, ensuring that each channel delivers maximum power when needed, without compromise.

Its power supply consists of a high-current toroidal transformer, paired with high-power filter capacitors (71VDC) with a total capacity of 100,000 µF, allowing it to easily handle rapid, demanding transient peaks while ensuring consistent performance even in the most dynamic situations.

The amplifier is equipped with Current Feedback discrete output stages, identical for all channels, using high-current discrete transistors with wide bandwidth. These stages are designed to extract the finest details from high-resolution audio formats, delivering rich and precise sound reproduction. Each channel is treated equally, guaranteeing a uniform and high-quality listening experience across all channels.

To provide maximum flexibility in system configuration, the MM8077 allows for the selection of balanced (XLR) and unbalanced (RCA) inputs for each channel, adapting to different connection needs. Thanks to its ability to easily handle low-impedance loads, the MM8077 can manage sound explosions and rapid transients without difficulty, making it ideal even for the most demanding speakers.
