Fusion MS-RA770 Marine Stereo Receiver: Touchscreen, AirPlay 2 and Wi‑Fi

The Fusion MS-RA770 is a purpose-built marine stereo head unit that brings true modern streaming to life on the water. Its bright 4.3-inch capacitive touchscreen is protected by a single, seamless glass display, delivering quick tactile control in bright sunlight and rough seas. This is more than a pretty screen—it's the central hub for tuning, source selection, and zone management on your boat.

At the core of the RA770 is Fusion’s advanced Digital Signal Processing (DSP), engineered to optimize sound for each listening zone—from the cockpit to the cabin. With DSP profiles that you configure via the Fusion-Link app, you’ll hear tighter bass, clearer mids, and perfectly balanced highs no matter how the boat is trimmed or how many speakers you’ve installed. This level of tailored sound helps you turn every voyage into a concert-quality experience.

Networking and wireless features set the RA770 apart for serious boaters. Built-in Wi‑Fi and Apple AirPlay 2 support let you stream high-quality audio directly from iPhone or iPad, while the PartyBus-networking capability lets multiple Fusion head units share audio and be controlled from a single interface. You can remotely turn other Apollo-series stereos on or off from a partner unit on the same PartyBus network, giving you effortless multi-zone control from anywhere on the boat. OTA (over-the-air) software updates ensure you stay current with new features without pulling the boat out of the water.

Source flexibility is a standout feature. The RA770 supports a broad array of inputs and streaming options so you can choose the best path for your music:

• Apple AirPlay 2, Wi‑Fi audio streaming, and Bluetooth
• AM/FM radio, USB audio, and digital optical input (TOSLINK)
• AUX inputs (x2), UPnP, and MTP for flexible device connections
• SiriusXM‑Ready (USA) for satellite radio with a separate tuner
• DAB+ compatibility (EU/Australia) for digital radio in supported regions

Combined, these sources give you nearly inexhaustible options for entertainment, whether you’re dockside or miles offshore. SiriusXM is US‑only and requires an adapter, while DAB+ is available in Europe and Australia; both are designed to work with Fusion’s DSP‑tuned profiles for consistent sound across environments.

Durability matters on a boat, and the Fusion Apollo MS-RA770 is built to endure. It features a marine‑grade front panel rated for the harsh realities of salt, heat, vibration, and UV exposure, ensuring reliable performance in challenging conditions. The unit is part of Fusion’s True Marine Design ethos, combining rugged hardware with software that stays responsive under real‑world boating conditions.

Why this matters in practice:

• Imagine hosting an on‑board party where every zone plays perfectly tuned audio from a single source, with the freedom to adjust the DSP profile from your bunk or the poise of the helm. The RA770 makes that a practical reality via Fusion-Link and PartyBus integration.
• Picture seamless streaming from your iPhone or iPad to multiple zones while you navigate or relax—AirPlay 2 keeps latency low and setup straightforward, even with multiple devices connected.
• Plan for the future with OTA updates that introduce new features and refinements without invasive service visits. The RA770 is designed to grow with your boat’s needs.

Who is this ideal for? Boat owners who demand cinematic sound and modern streaming on a marine system, installers seeking a robust, future‑proof head unit, and crews with multi‑zone listening requirements across cockpit, helm, and cabin. Its combination of touchscreen simplicity, DSP‑driven sound, AirPlay 2 streaming, and PartyBus network capability makes it a standout choice for premium yachts, sport boats, and cruisers alike. If you’re upgrading from an older marine stereo, the RA770 offers a tangible step up in usability, connectivity, and sound quality.

Designed and backed by Fusion Marine, this is not just a radio—it's a complete audio entertainment solution engineered for the marine environment. Whether you’re chasing concerts at sea or simply setting the mood for a sunset cruise, the MS-RA770 delivers clean, powerful sound with the versatility modern boaters expect.
