2021 NMEA Awards: Multimedia Entertainment: Fusion Apollo MS-RA770

The world’s first touchscreen marine stereo with Apple AirPlay 2 and built-in Wi-Fi, the Apollo RA770 includes Fusion’s digital signal processing and enhanced PartyBus-Network capabilities. It has garnered numerous accolades since it was introduced and now adds to that collection with the 2021 National Marine Electronics Association (NMEA) Award for Multimedia Entertainment.


The Apollo MS-RA770  is the first stereo in the recreational boating industry that lets a user stream via Apple AirPlay 2 over Wi-Fi from a compatible Apple device to the stereo unit. Apple AirPlay 2 has the added functionality of being able to stream one audio source from an Apple unit to multiple Apollo series stereos on the same network with individual and global volume control of the head units. Software update v3.00.83 is required and AirPlay 2 is not supported over the PartyBus Network.

Additionally, with the Apollo MS-RA770 delivers audio streaming that is now available via Wi-Fi, delivering a higher transfer rate compared to Bluetooth. Music is synched throughout a vessel by connecting multiple Apollo series units via the PartyBus-Network.

Digital Signal Processing

Fusion says Digital Signal Processing (DSP) produces superior sound quality. Precisely calculated loudness curves are optimized for full-range audio at all volume levels. The feed forward limiter anticipates a peak in the audio and adjusts the gain to eliminate distortion. Using environmental information and customized Fusion speaker profiles, the listener can achieve customized, optimized audio for any area of a boat.

Setting up the DSP profiles is easier with the Fusion-Link app or with a custom-made Fusion-Link PC app for OEM boat builders. With a few clicks, a user can set up the preconfigured DSP profile once and get back to enjoy being on the water.


Fusion’s PartyBus-Network provides freedom of musical choice. The company has introduced a new intuitive user experience that permits easy navigation of a boat’s entire audio network. Stereo grouping lets a user link multiple Apollo Series stereos connected to the same network and play the same audio source synchronized across all units. Multiple groups can be created for a personalized listening experience. Apollo SRX400 sources are not shared on the network.

Scroll through available zones on a boat to enjoy independent volume control for a given area or select All volume to crank the tunes on every speaker throughout a boat. Power Options let any stereo connected to the network turn on another unit anywhere in the boat. Home Zone is the physical Zone on the vessel where the stereo is installed. After adjusting the audio in another zone, the stereo will default back to audio control of the Home Zone after a period of inactivity.
