Smart connectivity and DSP audio on board

Stream high-quality music over Wi-Fi and enjoy perfectly synchronized sound on your boat by wirelessly connecting multiple stereos with PartyBus. With Apple AirPlay 2, you can stream from a compatible Apple device to multiple Apollo stereos on the same network and control volumes individually or globally. Please note: an Apollo RA770 is required for PartyBus, and AirPlay 2 does not work with PartyBus.

Built-in Digital Signal Processing optimizes sound for any environment. Pre-calculated loudness curves and a feed-forward limiter prevent distortion, while speaker profiles ensure balanced reproduction. The free Fusion-Link app makes it easy to set the right DSP profile, and your system is ready for consistent, enjoyable sound on board.
