Description
Marantz Model M4 – Four-Zone Distribution Amplifier with HEOS®
Bring the legendary Marantz sound to every room with the Model M4, a high-performance multi-zone amplifier designed for audiophiles and integrators alike. Crafted in Shirakawa, Japan, this rack-mountable powerhouse combines refined engineering with modern streaming intelligence, making it the perfect centrepiece for whole-home audio.
The Model M4 delivers eight channels of 100 watts each with the option to bridge into four channels at 200 watts for added flexibility. Even when driving all zones at once, it maintains the clarity, detail, and warmth that define Marantz. Each of its four zones comes with its own HEOS® streaming module, so you can enjoy different music in different rooms or synchronize playback throughout your home.
Connectivity is comprehensive: four RCA inputs, two optical digital inputs, USB-A ports, and Ethernet ensure seamless integration with your existing sources. Built-in support for HEOS®, AirPlay 2, Spotify Connect, and Tidal puts streaming at your fingertips, while advanced digital audio compatibility lets you enjoy high-resolution formats such as FLAC, ALAC, WAV, and DSD.
For fine-tuning, the Model M4 includes adjustable filters, EQ, and sound modes such as Direct, Night, and Virtual to match your environment and preferences. Professional installers will appreciate its control options—Ethernet ports, 12V triggers, and compatibility with Crestron, Control4, and AMX systems—making it as reliable in custom integrations as it is powerful in performance.
With a sleek 2U rack-mount design, active cooling, and elegant black finish, the Model M4 looks as good as it sounds. Whether you’re building a high-end smart home or upgrading your entertainment system, this amplifier delivers uncompromising performance, intuitive streaming, and timeless Marantz quality—room by room.
