Features:
Built-in Digital Signal Processing (DSP)
A technically superior listening experience made simple, DSP optimizes the audio signal for superior sound quality in every listening environment. Custom audio profiles (including speaker, subwoofer, amplifier and environment) can be setup for each zone on your boat using the Fusion-Link™ app on your compatible smart device.
PartyBus™-Network Technology
Enjoy the freedom of musical choice across the entire boat by connecting multiple Apollo™ Series stereos together using Ethernet. An intuitive user experience allows you to control stereo grouping (play the same audio source across multiple stereos in sync), volume, power options and more. 
Gain Wi-Fi® Capabilities
Enjoy seamless Wi-Fi® audio streaming with Apple AirPlay® 2 and the convenience of over-the-air software updates when connected via Ethernet to an external wireless network router (sold separately), Garmin MFD or Apollo™ Series stereo network enabled with Wi-Fi technology.
Optically Bonded Color LCD Display
Brilliant 2.7" optically bonded color LCD is integrated into the black front face and supports album art and track information.
Fusion-Link™
A widely adopted protocol for on-water audio integration and control. Allows you to control your audio from a compatible multifunction display (MFD), smart device or Garmin watch.
Multi-Zone™ Technology
Up to three independent audio zones are available for a customized listening experience across your boat, each with advanced localized audio options, including volume limits, zone naming, disabling zones and more. (Note: Subwoofer and full range line outs require additional amplification.)
Advanced Source Options
Take advantage of the many source options available including Apple AirPlay 2®, BLUETOOTH®, Universal Plug and Play (UPnP), optical audio, advanced SiriusXM® features, DAB+ radio, AM/FM radio, AUX and USB connections.
