Looks good. Sounds great.

Fusion's Apollo MS-RA670 blends sleek styling, cutting-edge technology, and marine-ready toughness in one compact package. With a beautiful one-piece glass display, multiple source options, and Fusion's advanced digital signal processing (DSP), this is one seriously awesome receiver.

The awesome Fusion-Link app

Fusion-Link is the industry standard protocol for marine audio integration and control. This free app 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.

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.

Hear the difference DSP can make

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 multi-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.

Scads of source options

How do you listen to your music these days? Whatever the answer, the Apollo MS-RA670 can probably handle it. There's AM/FM radio, of course, plus Bluetooth, UPnP, and an optical digital audio input. Plug a device in to the AUX or USB connections, or listen to your favorite SiriusXM programming (subscription and tuner required). And perhaps best of all, you can also stream high-quality audio from compatible Apple devices using Apple Airplay.

The Apollo MS-RA670 can be used in a Wi-Fi system when connected to an external network router or a Fusion Apollo RA770 stereo. If you're building a big system, you can enjoy perfectly synced music everywhere on a larger boat by wirelessly connecting multiple Fusion MS-SRX400 zone stereos via Fusion's PartyBus™ audio distribution technology.

Get into a zone

The MS-RA670 lets you control the sound in three independent audio zones, so you can customize your listening experience all around the boat. Each localized menu lets you control volume limits, zone naming, zone disabling, and more. All line-outs will require additional amplification, so talk to a Crutchfield Advisor for more information about building a system.

Multiple modes to suit your mood

You can rock the boat with Party Mode, turn it down a bit with Personal Mode, and switch between the two without disrupting the audio in other areas of the vessel.

Glass touchscreen display

The all-glass 2.7” LCD color display isn't just another pretty face, it's a beautifully simple way to control your RA670. Just tap the screen to pause and play, or swipe through your playlist to your favorite song. No more fiddling about for the right button while you're underway.

True-Marine™ toughness

The Apollo MS-RA670 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 stand up against salt fog, temperature, vibration, and damaging UV rays.

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 marine digital media receiver will not play CDs.

    The RA670 was a great addition to my Intrepid Center Console.

    Crutchfield customer from Spring Lake, MI on 7/15/2019

    Verified customer (What's this?)
    Verified employee purchase (What's this?)

    I really like this unit, has great sound, very easy to use volume and music control buttons. Easy integration with my Garmin GPS using NMEA 2000, and the 5 volt pre-outs give my JL-Audio amps a nice strong of signal. Three zones is plenty for my center console. Not having built in WiFi is the only con for me, but saving $200 compared to the RA770 eases the pain. I highly recommend this unit!

    Pros: Built in blue tooth, NMEA 2000, integration with Garmin GPS, very easy to use controls, 5 volt pre-outs.

    Cons: No built in WiFi.

    Audio Section

    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 (sold separately) 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.

    9Ch/5.5V Pre-outs: The Apollo Series MS-RA670 is also equipped with stereo RCA Zone 1, Zone 2, and Zone 3 pre-outs for connection of external amplifiers and speakers in four separate locations on your watercraft; plus a mono-Sub pre-out for each zone (that's a total of nine pre-outs). Each pre-out is rated at 5.5 volts and each Zone provides independent volume control. The subwoofer pre-outs provide further volume and crossover control.

    Multi-Zone Technology: Three independent audio zones are available for a customized listening experience across your vessel, each with advanced localized menu controls including volume limits, zone naming, disabling zones and more. Zone 1 and Zone 2 provide amplified speaker level outputs, as well as line-level pre-outs. Zone 3 offers line-level pre-outs only. The full-range and subwoofer line-level outputs of each Zone will require additional amplification.

    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.
