MARANTZ MM7055

The MM7055 is a five-channel power amplifier designed to deliver power and precision, making it ideal for advanced home theater systems. With a power output of 140W RMS per channel at 8 Ω, it can easily handle even the highest frequencies, making it perfect for high-definition audio formats like DTS Master and Dolby TrueHD. Thanks to its ultra-wideband current feedback technology, the MM7055 ensures smooth and precise sound reproduction, with accurate spatial and tonal balance that supports speed and dynamics without distortion.

The amplifier is designed using the same chassis and technology as the MM8003, providing stable power delivery through a robust power supply. Its EI-core transformer with multiple secondary windings and an energy storage capacity of over 65,000 µF ensures consistent performance, even during the most demanding listening sessions.

The MM7055 features both single-ended RCA and balanced XLR inputs, offering flexibility in connecting with various audio devices. For added convenience, the type of input can be selected for each channel. Additionally, the gold-plated four-way binding posts ensure secure and stable connections to speakers.

The amplifier also includes DC triggers and the Marantz bus system, allowing for remote control of power on/off, enhancing the management of the audio system. The integrated elegant display provides real-time information about the output power, completing a functional and efficient design. In summary, the MM7055 is a powerful and versatile solution for home theater enthusiasts seeking high-level sound performance.
