Features:
Industry-First Marine Stereo With Apple AirPlay 2: With the Apollo Series you can stream high quality audio seamlessly via Apple AirPlay 2 over Wi-Fi from your compatible Apple device to the Apollo RA770. Apple AirPlay 2 has the added functionality of being able to seamlessly stream one audio source from your compatible Apple device to multiple Apollo Series marine stereos connected to the same network, with individual and global volume control of the head units. Note: Software update v3.00.83 is required. AirPlay 2 is not supported over PartyBus-Network.
World’s First Marine Wi-Fi Stereo: High quality audio streaming is now available via Wi-Fi, delivering a higher data transfer rate in comparison with Bluetooth. Enjoy perfectly synced music throughout your vessel by wirelessly connecting multiple Apollo stereos via a PartyBus-Network.
Digital Signal Processing (DSP): A technically superior listening experience made simple, Fusion DSP produces superior sound quality in every environment. Precisely calculated loudness curves optimized for the human ear ensure quality, full range audio at every volume level, while the feed-forward limiter anticipates a peak in the audio and adjusts the gain to make distortion, at any volume level, a thing of the past. 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.
Setting up your DSP profiles is made simple with the free Fusion-Link app, 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. 
PartyBus™-Network: Enjoy the freedom of musical choice with the Apollo Series and Fusion's PartyBus-Network. We have introduced a new intuitive user experience allowing for easy navigation of your entire boat's audio network, making control of your audio and sources a seamless experience. Key functionalities include:
Stereo Grouping, allows you to link up multiple Apollo Series stereos connected to the same network and play the same audio source synchronized across all stereos. Multiple groups can be created for a personalized audio entertainment experience. Note: Apollo SRX400 sources are not shared on the network.
Volume Control, scroll through available zones on your vessel and enjoy independent volume control to customize your listening experience, or select ALL volume to adjust a group of stereos at once.
Power Options, allows you to turn on any connected Apollo Series stereo on the PartyBus-Network remotely from another Apollo Series stereo.
Home Zone, is the physical zone on board your vessel where the stereo is installed. After adjusting audio in another zone, the stereo will default back to audio control of the Home Zone after a period of inactivity.
Glass Touchscreen Display: The future of marine audio entertainment has arrived in the Apollo RA770 with its 4.3” LCD color touchscreen display. Simply tap the screen to pause and play, or swipe through your playlist to your favorite song – fiddling around to locate the right button is now a thing of the past.
Over-The-Air Software Updates: The Apollo Series is intelligently simple and always up to date, thanks to the over-the-air software updates available over Wi-Fi from your smartphone or compatible device via the free Fusion-Link app.
More Source Options Than Ever Before: The Apollo RA770 features more source options than ever before, with Bluetooth, UPnP, Optical Audio, advanced SiriusXM features and DAB+ radio available, AM/FM radio, AUX and USB connections ready at your fingertips.
