Apollo MS-SRX400 Stereo w/AM/FM/BT - Single Zone w/DSP

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 subwoofer.

Digital Signal Processing (DSP) A technically superior listening experience made simple, Fusion's 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, a thing of the past. Using environmental information and acoustically designed 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.

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, volume control, power options and home zone technology.

Wi-Fi Audio Streaming  In a marine industry-first, high quality on-board audio streaming is now available via Wi-Fi with the Apollo Series.  Wi-Fi streaming provides a higher data transfer rate in comparison with Bluetooth, for higher quality audio reproduction.  Enjoy perfectly synced music throughout your vessel by wirelessly connecting multiple stereos via a PartyBus-Network.

Fusion-Link™ Makes control of your stereo easier than ever.  Quickly find your favorite song, tune in to the sports or turn up the volume all from your partnered multifunction display (MFD), compatible smartphone, Garmin Handheld or Garmin watch.  With the app installed, you can enjoy source navigation and track selection from wherever you are on your boat.
