About the Fusion MS-SRX400

Expand your Apollo audio system

If you want to build a cutting-edge multi-zone audio system on your boat, Fusion's Apollo Series has everything you need. Start with a Fusion MS-RA770 or MS-RA670 touchscreen marine receiver, then add one or more of these MS-SRX400 zone receivers in other zones on your boat. You can sync up all the music on the boat with Fusion's PartyBus™ feature, or use each MS-SRX400 as an individual entertainment source. You can use its built-in amp to power stereo speakers in your zone, or use the preamp outputs to add amps to power the speakers and a sub.

You can use its built-in amp to power stereo speakers in your zone, or use the preamp outputs to add amps to power the speakers and a sub.

It's all about the app

Fusion-Link, the industry standard protocol for marine audio integration and control, lets you control your entertainment directly from marine multi-function displays, compatible Apple or Android devices, and Garmin watches. You can choose from multiple control options and adjust your audio from wherever you are on your boat. One of the best things about Fusion-Link is that you can access the receiver's digital signal processing settings. Fusion's DSP uses precisely calculated loudness curves to let you enjoy a full sound at every volume level without distortion. And your Apollo Series receiver will always be up to date, thanks to over-the-air software updates.

NEW! Fusion Apollo receivers and zone receivers can now stream high-quality audio from compatible Apple devices using Apple Airplay. The feature is standard on newer models, but if you already have a Fusion Apollo Series reveiver, you can add it via a software update from Fusion

Dig your tunes with DSP

One of the best things about Fusion-Link is that it lets you control the receiver's digital signal processing settings. The Fusion DSP's feed-forward limiter anticipates peaks in the audio and automatically adjusts the gain, so you can enjoy full-range audio at every volume level without distortion. You can also customize this zone receiver's sound settings to suit your Fusion speakers or adjust the settings to maximize performance in any area of your boat. With this Apollo Series receiver, everything will sound awesome anywhere you are.

Compact design for sleek installations

The compact Apollo SRX400 can fit into small spaces, so you should have plenty of installation options. Whether you choose a conventional flush installation, or integrate yours into into a glass helm for a premium finish, your marine system will be a lot more awesome.

Over-the-air updates

Your Apollo Series receiver will always be up to date, thanks to over-the-air software updates. All you need to do is use the Fusion-Link app on your smartphone or compatible device.

NEW: Fusion Apollo radios can now stream high-quality audio from compatible Apple devices using Apple Airplay 2.

True-Marine™ toughness

The Apollo MS-SRX400 zone receiver is designed and engineered using Fusion's True-Marine design philosophy. That means it's more than tough enough for life on the water. The front panel is IPX7-rated for water resistance, and it's also proven to protect against salt fog, temperature, vibration, and damaging UV rays.

Note: The Fusion MS-SRX400 can be used as a stand-alone receiver or integrated into a larger Fusion Apollo marine audio system.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

iPod/smartphone note: If you're going to use your iPod® or smartphone with this receiver, be sure to check "Details" for compatibility information.

This zone receiver will not play CDs.

    Product Research


    Apollo Series SXR400: The MS-SRX400 combines the latest design, engineering and powerful feature set of Fusion's Apollo Series in a compact, versatile form factor. With built-in WiFi & Bluetooth audio streaming, Fusion's Digital Signal Processing, PartyBus connectivity, a built-in AM/FM tuner, and over-the-air software updates, the Apollo MS-SRX400 is the perfect combination of intelligent design and superior sound in a compact zone stereo.

    • True-Marine Designed & Engineered: Built on Fusion's True-Marine design philosophy, the MS-SRX400 has an IPX7 water resistant front-panel, and has been tested to a high level for protection against salt fog, temperature, vibration and UV protection.
    • Optically Bonded 2.7" LCD: The 2.7" color LCD is optically bonded to improve durability and protection against condensation and fogging. The 2.7" screen has been optimized for daylight viewing and offers brightness adjustment. The color LCD indicates source and menu selection, as well as displays song/artist info (including album art).
    • Front-Panel Controls: Six push-buttons and a 3-way rotary knob provide control of the MS-SRX400 from its front-panel. The 3-way rotary knob does double-duty as a volume control and menu selector. The push-buttons provide power on/off, menu screen, source selection, and playback control (including Play/Pause & Previous/Next Track).

    Available Sources: The Apollo Series MS-SRX400 offers built-in WiFi, AirPlay 2, and Bluetooth for wireless audio streaming, as well as a built-in AM/FM tuner.

    • Built-in WiFi with UPnP Support: The Fusion MS-SRX400 offers high quality audio streaming via WiFi (2.4GHz), delivering a higher data transfer rate in comparison with Bluetooth. The MS-SRX400 supports UPnP for wireless streaming of MP3, AAC, WAV, and FLAC audio files from a UPnP compatible source device (such as your Windows PC or media server). The receiver will provide control and song/artist display of your UPnP music content.
    • Apple AirPlay 2 (firmware update available): Through a firmware update you can now stream high quality audio seamlessly via Apple AirPlay 2 over WiFi from your compatible Apple iOS (4.3.3+) device to the MS-SRX400. You'll be able to stream your Apple Music or your favorite music apps from your Apple iOS device to the MS-SRX400 with song/artist/album info display (including album art). You will need to download the latest firmware update from the Fusion website onto a USB thumbdrive and then insert the thumbdrive into the USB port of the MS-XRX400.
    • Bluetooth Audio Streaming: The Fusion MS-SRX400 marine stereo features built-in Bluetooth 3.0 with support for wireless music streaming from almost any Bluetooth-enable device (such as your smartphone or tablet). The MS-SRX400 supports wireless audio playback (AD2P 1.2) and control (AVRCP 1.3) of a Bluetooth-enabled device. The MS-SRX400 will wirelessly play back stored music, music apps, and other audio on your Bluetooth source device. With an effective range of 10 Mtrs (33ft), you can enjoy seamless streaming of your favorite audio tracks without having to return to the stereo to change tracks.
      • Control: The unit will be able to control basic playback functions, such as Play/Pause & Skip Next/Previous. Advanced music control of your music apps will still need be done via your Bluetooth source device.
      • Display: Song/artist information, along with Album Art is displayed on the receiver's LCD screen.
      • Pairing: You can pair up to 8 Bluetooth devices, but only one can be connected and used for playback at a time.
    • AM/FM Tuner: The Apollo Series MS-RA770 marine stereo features a built-in AM/FM radio that offers manual, seek, and preset tuning. You can store up to 15 FM station presets and 15 AM station presets. You can select between US and European tuning. Separate marine antenna is required and sold separately.

      Notes: This unit does not support Bluetooth hands-free communication for making and answering phone calls. It does not offer an Aux input or USB ports.

    PartyBus: PartyBus is Fusion's wired (Ethernet) or wireless (WiFi) network audio distribution system of the future. The power of PartyBus kicks in when you add more PartyBus-enabled stereos (via a wired or wireless network connection) to your marine entertainment system. Each additional PartyBus-enabled stereo gives you the option to join Party Mode and play the same perfectly synced audio source through the vessel. Or, you can select Personal Mode and listen to available audio sources from your stereo in the area of your choice without disrupting Party Mode in the other areas of the vessel.

    • You can connect up to eight Fusion PartyBus devices (including the MS-RA670, MS-RA770 and MS-SRX400) on one network.
    • At least one Apollo MS-RA670 or MS-RA770 stereo is required in the PartyBus network.
    • The MS-SRX400 can stream from a Fusion PartyBus stereo (such as the MS-RA670 or MS-RA770), but cannot stream sources to other Fusion PartyBus devices on the network.
    • Fusion PartyBus devices cannot control the speaker volume of another stereo. You can only adjust the volume of speakers or speaker zones connect directly to the PartyBus stereo.

    Note: AirPlay 2 is not supported over PartyBus.

    2Ch Class-D Amplifier with 3Ch Pre-Outs: The Fusion MS-SRX400 is equipped with a Class-D amplifier that is rated at 26 watts (RMS) x 2 channels into 4 ohm or 43 watts (RMS) x 2-channels into 2 ohm. It is also equipped with 3ch pre-outs (Left, Right, & Sub). The subwoofer pre-out provide independent volume and crossover control. The MS-SRX400's speaker and line-level outputs are configured for a single zone (not multi-zone compatible).

    Digital Signal Processing (DSP): Fusion digital signal processing (DSP) produces superior sound quality in the outdoor marine environment. The power of Fusion DSP enables the optimization of Fusion speakers in each audio zone on your vessel, giving you premium audio delivery to all Fusion speakers in any environment. Every step of the audio chain is optimized through calculations by Fusion's audio engineers to deliver a technically superior listening experience, without the need for you to have a technical understanding. Using environmental information and customized Fusion speaker profiles, you can now achieve customized, optimized audio for any area of your boat, resulting in an entertainment system that is perfectly tuned for premium audio reproduction, and programmed to protect your system season after season.

    • Feed-Forward Limiter: The Feed-Forward Limiter anticipates a peak in the audio and adjusts the gain to avoid distortion, at any volume level.
    • Volume Equalizer: The Volume Equalizer precisely calculates loudness curves optimized for the human ear to ensure quality, full-range audio at every volume level.
    • Speaker Profiling: Customized Fusion speaker profiles enables the optimization of Fusion speakers in each audio zone on your vessel, giving you premium audio delivery to all Fusion speakers.
    • Environmental Profiling: Using environmental information you can achieve customized and optimized audio for any area of your boat, resulting in an entertainment system that is perfectly tuned for premium audio reproduction.
    • Tone Control: The MS-SRX400 offers Bass, Midrange, and Treble adjustment; as well as a Loudness control.

    Optional Ethernet Remote Control: The Fusion Apollo MS-ERX400 (917ERX400, sold separately) adds wired remote control for intuitive and integrated operation of the MS-SRX400 from any zone on board your boat. This wired remote control can either connect to a single stereo or it can connect to the Fusion PartyBus network to view and control all of the stereos on the network. Enjoy synchronized audio playback of one audio source across all Apollo Series stereos connected to the same network, with individual and independent volume control for each stereo. The Apollo MS-ERX400 can also be used to turn on or off any Apollo Series stereo or remote connected on the network.

    Fusion-Link App: Setting up your DSP profiles is made simple with the free Fusion-Link app (for Apple iOS 8.0+ and Android 2.2+) or with a custom-made Fusion-Link PC app for OEM boat builders. With just a few clicks, you can set up the preconfigured DSP profile once and get back to enjoying what you love on the water, while listening to high quality audio customized for your ears and the environment. The Fusion-Link app also lets you adjust volume level, change the source, control playback, select and manage radio presets, and adjust menu settings from your compatible Apple iOS or Android device.

    Note: The app can communicate with the MS-SRX400 over a wireless Bluetooth or WiFi connection.

    Over-The-Air (OTA) Software Updates: The Apollo Series is intelligently simple and always up-to-date, thanks to the over-the-air (OTA) software updates available from your Apple iOS or Android mobile device via the free Fusion-Link app.

    Compact Design: The compact Apollo MS-SRX400 zone stereo is designed for installation where minimal space is available, providing high quality audio reproduction from a compact form factor, either in a conventional flush installation, or integrated into a glass helm for a premium finish. The MS-SRX400 requires a rectangular cutout in the bulkhead for inserting the chassis. The marine receiver has a shallow mounting depth, perfect for space conscious installation on small boats and personal watercraft, where this is especially crucial.

    • Chassis Dimensions: 3.25" (w) x 2.0" (h) x 4.0" (d)
    • Front-Panel Dimensions: 4.1875" (w) x 2.75" (h) x 0.875" (d)
    Note: Four screws (supplied) fasten the faceplate against the mounting surface, and hold the waterproof gasket against the bulkhead. A paper template is supplied to assist you with the cutout and drilling the screw holes.

    Customer Q&A

    13 questions already asked

    What amplifier and subwoofer would work with this unit if I am looking to expand my existing SeaRay system?
    [ Brooks  Jun 27, 2022 ]
    1 answer
    The Fusion MS-SRX400 can work with many different amplifiers and subs. There is many possible sub and amp combinations that could work. The subwoofer is really more of a personal preference depending on how much bass is wanted for this set up. Space may also be a factor as well. Once a subwoofer is chosen we then match the sub to an appropriate amplifier based on wattage and impedance of the subwoofer. If you need help finding a solution, we're very happy to help! Give us a call at 1-800-324-9695 and we'll be happy to help you find what works for you!
    [ Allison  Jun 27, 2022 ]  Staff
    Can you listen to SirrusXM through the speakers connected to the MS-SRX400 if the satellite radio adapter is connected to the MS-RA770 and have the main zone speakers where the MS-RA770 is located be off?
    [ PhiberOptik  Jan 16, 2022 ]
    1 answer
    If the MS-RA770's zones are muted, you can still have SiriusXM playing and controlled in the MS-SRX400 zone. You will not be able to control the volume of the SRX400 zone from the RA770 and vice versa. If you are still building the system, however, you can utilize the 4 independent zones of the RA770 with an amplifier for the zone that you currently want the SRX400 to power and pair a remote control like this one: That will give you more control of the overall system from both locations. Feel free to reach out to one of our Advisors any time at 1-800-309-2075 for help building this system!
    [ Davis  Jan 23, 2022 ]  Staff
    Can you link 2 MS-SRX400 together with out having a MS-RA670-770?
    [ Iansulz  Jun 30, 2021 ]
    1 answer
    No, you must have at least one 670 or 770 to use the Partybus network feature.
    [ Calvin  Jul 14, 2021 ]  Staff
    Dose the ARC-400 have SCV?
    [ Kygwalt  Jun 09, 2021 ]
    1 answer
    If you are referring to speed controlled volume, this receiver does not have it. Other receivers might have this ability. I recommend contacting an advisor by calling 1-800-324-9695 who can check our current models for a this ability. Also, if that is not the ability you are referring to, then I recommend you call them to discuss your goals in greater detail to get a personal recommendation on a receiver that works.
    [ Paul  Jun 12, 2021 ]  Staff
    Does the fusion arc-400 act as a stand-alone or does it need a hideaway reciever like the JL Ms-50?
    [ Brian  Apr 02, 2021 ]
    1 answer
    This Fusion unit can be a stand alone receiver or work with a couple other Fusion units for a partybus setup. I recommend contacting an advisor by calling 1-800-324-9695 to get a personal recommendation on the gear needed to build your system with the control you seek
    [ Paul  Apr 18, 2021 ]  Staff
    Can the srx 400 be controlled by a MFD such as Simrad NSS Evo 3? There is no NMEA 2000 connection.
    [ Mike  Jul 09, 2019 ]
    1 answer
    It cannot. the SRX400 is not controllable from Simrad, or NMEA 200 networks, it is expandable using the proprietary fusion PartyBus network, however.
    [ Calvin  Jul 17, 2019 ]  Staff
    Can an amp with sub be added to this? Will artwork from Pandora display on screen?
    [ Eric  Jun 26, 2019 ]
    1 answer
    You can definitely add amplifiers to this unit. It does not display artwork from Pandora however.
    [ Calvin  Jul 04, 2019 ]  Staff
    Does this have USB input or is the only input via a smart p[hone?
    [ James  Jun 26, 2019 ]

    There's no port. It just connects via Bluetooth
    [ Bryan  Jun 26, 2019 ]
    No cat5 cable only
