Rack-mountable, fan-cooled, and powered by four independent HEOS streaming modules, the Model M4 brings audiophile-grade amplification and modern wireless streaming to four independently controllable zones, making whole-home multi-room audio effortless for music lovers and custom installers alike.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eDistribution Done Differently\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Marantz Model M4 is an innovative, intelligent take on traditional distribution amplifier designs. With 8 channels of 100W amplification split into four independent zones, the Model M4 delivers no decrease in power even with all channels driven, giving you complete control over four separate rooms from a single chassis. Each zone has its own dedicated HEOS streaming module, analog input, USB-A input, and subwoofer output, so every room can play something completely different at the same time.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003ePowered by HEOS Wireless Multi-Room\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFour built-in HEOS modules let you stream your favorite music or TV audio independently or grouped across four different rooms. Use HEOS in up to 24-bit \/ 192 kHz PCM and DSD quality, or stream via Apple AirPlay 2, Spotify Connect, or Bluetooth from any compatible device. The Model M4's TV Grouping feature lets you stream the same TV audio across connected rooms seamlessly, perfect for game day or whole-home entertaining.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eBuilt for Integrators, Beautiful Enough to Display\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Model M4's industrial design complements the latest generation of Marantz hi-fi and AVR products, making it more than attractive enough to leave out in the open. Its rack-mountable design also makes it ideal for discreet installations where electronics are kept out of sight in a central AV closet. Twin Ethernet connections, IP control, RS-232, and 12V triggers ensure the Model M4 integrates cleanly into any custom installation control platform.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100
