Product Description
Model M4 – Overview
MODEL M4 is an innovative and intelligent take on the modern distribution amplifier. Rack mountable, fan cooled, and boasting eight channels of 100W, split into four zones, MODEL M4 delivers superb high-resolution Marantz sound throughout your home. Each zone boasts its own HEOS® music streaming module, so you can stream using AirPlay 2, Spotify Connect, TIDAL, and more. Additionally, four USB-A and four analog inputs provide further flexibility, while the audio from your TV can be accessed via two optical connections and the onboard Dolby Digital decoding. MODEL M4 can be controlled using the HEOS® app or the most popular integrator-friendly control platforms.
Power Where You Need It
With an output of 8 x 100W with 0.05% THD, MODEL M4 delivers more than enough onboard power to drive even demanding speakers across four separate rooms in your home. For even more power, simply use Bridge Mode, which offers up to 4 x 200W of output, or pair your MODEL M4 with offboard power amplifiers in each room. Connect your active subwoofers using the same preout sockets for an even more fully extended listening experience.
Any Sound, Anywhere
MODEL M4 features four built-in HEOS modules, four USB-A inputs, and four analog inputs to deliver effortless independent listening in four separate rooms in your home. Play the same song in every room or select a different song for each connected zone. Use HEOS® in up to 24-bit/192kHz PCM and DSD quality, or AirPlay 2 or Spotify Connect—the choice is yours. Plus, MODEL M4’s TV Grouping feature means you can stream the same TV audio across your connected rooms seamlessly.
Fully Featured, Fully Flexible
With all the onboard features every integrator could need, MODEL M4 makes multiroom effortless. Use HEOS® to share music with existing Marantz hi-fi or AVR products, connect your devices with twin Ethernet connections, add MODEL M4 to your rack using its intuitive rackmount design, and pair multiple MODEL M4s for the ultimate whole-home music distribution system. While MODEL M4 does the heavy lifting, its active thermally triggered fan cooling keeps things running smoothly.

Marantz Musical Digital Filtering
Marantz is recognized for sound quality that celebrates the natural warmth, detail, and spaciousness found in the best-quality recordings. Marantz Musical Digital Filtering (MMDF) ensures those analog-like characteristics are preserved, even with digital music playback. These unique oversampling digital filtering techniques, first developed for Marantz reference-grade audiophile products, are instrumental in delivering the MODEL M4’s musical and engaging sound.
High Power, Low Distortion, High Efficiency
MODEL M4 harnesses the amplification excellence Marantz is renowned for. Featuring eight channels of 100W, which can be bridged to deliver up to four channels of 200W, MODEL M4 provides the high power, low distortion, and high efficiency your home audio setup demands. With assignable stereo pre-outs, add external power amplifiers for even more power.
Flexible Subwoofer Outputs
MODEL M4’s four dedicated subwoofer outputs ensure it is fully equipped to deliver sound with room-filling scale to any area of your home. Connect four different subwoofers in four different rooms and adjust the high-pass and low-pass filter frequencies independently using the HEOS® app. More bass, more power, more control.
Elegant Industrial Design
MODEL M4 is engineered to work everywhere. Its smart design features a steel chassis, brushed aluminum front face, and the iconic Marantz porthole with four white LED zone indicators. The design is subtly elegant when placed in view, but robust enough that it can be placed in a rack.
