Marantz MODEL M4 Four Zone Distribution Amplifier
Marantz Model M4 Four Zone Distribution Amplifier – The Ultimate Multiroom Music Streamer for Your Home
Enhance your home audio experience with the Marantz Model M4 Four Zone Distribution Amplifier—the perfect solution for seamless multiroom and multisource streaming. Designed to deliver robust sound and versatile streaming options, this Marantz amplifier offers an all-in-one music streaming solution for up to four rooms, making it ideal for homes seeking high-quality audio in multiple spaces.
One-Box Music Streamer for Four Zones
The Marantz Model M4 stands out as a powerful four-zone distribution amplifier. Unlike conventional amplifiers, the Model M4 lets you play different music in each room, all from a single, compact device. With dedicated HEOS music streaming built-in for every zone, this Marantz amplifier transforms your entire home into a streaming hub, effortlessly delivering unique audio to four separate areas.
High-Powered Amplification for Every Zone
Equipped with 100 watts per channel, the Model M4 offers more than enough power to fill even large rooms with rich, immersive sound. Connect any speakers of your choice to each zone, and if you want a deeper bass, add an active subwoofer to any room using the preouts. Alternatively, you can link active speakers directly for flexible listening setups across your home.
Marantz Musical Digital Filtering for Pure Sound
Every note, every beat—Marantz Musical Digital Filtering (MMDF) ensures your music retains its natural tone and detail. Tuned by Marantz’s Sound Master, the Model M4’s advanced digital filtering technology enhances the sound quality, capturing the subtle nuances in your favorite tracks and creating a truly engaging listening experience.
Multiroom Audio with HEOS x4
With HEOS built-in, the Marantz Model M4 seamlessly integrates into your multiroom music system. The HEOS app provides access to popular streaming services like Spotify, Tidal, Amazon Music, and Deezer. Supporting up to 32 HEOS-compatible devices, it ensures that every room in even the largest homes can be part of your music experience.
Effortless Control with the HEOS App
The HEOS app (compatible with Apple iOS, Android, and Amazon Kindle) makes it easy to control music across your home. Stream saved playlists, access Internet radio, and browse popular streaming services, all from one intuitive app. Control the volume, source, and playback in every zone right from your smartphone or tablet.
Apple AirPlay 2 and Spotify Connect Compatibility
Beyond HEOS, the Marantz Model M4 supports Apple AirPlay 2 for a seamless connection with your Apple ecosystem, allowing you to stream music from iPhone, iPad, and Mac devices. Additionally, Spotify Connect offers direct connectivity for an enhanced listening experience. (Note: Network connectivity requires Ethernet, as Wi-Fi is not built-in.)
Flexible Connectivity for All Your Devices
In addition to streaming, the Marantz Model M4 offers diverse connectivity options. With four RCA analogue inputs and two assignable optical digital inputs, you can link a variety of audio sources—such as a CD player, gaming console, or TV sound—to specific zones. Four USB inputs allow you to access and stream music from media devices across your network, bringing ultimate versatility to your multiroom setup.
Experience the full power of multiroom music with the Marantz Model M4 Four Zone Distribution Amplifier—your ultimate solution for flexible, high-fidelity sound throughout your home.
