Fusion Apollo MS-SRX400 Marine Zone Stereo
Product Overview:
The Fusion Apollo MS-SRX400 is a compact, high-performance marine zone stereo designed to provide a premium audio experience in smaller spaces. As part of the Apollo Series, it features built-in Wi-Fi streaming, Apple AirPlay 2, and Digital Signal Processing (DSP). It is uniquely versatile, functioning as either a powerful standalone stereo or an integrated part of a larger PartyBus™-Network, making it the ultimate solution for zoned audio on any vessel.
Key Features
World’s First Marine Wi-Fi Stereo
The MS-SRX400 offers high-quality audio streaming via Wi-Fi, providing a significantly higher data transfer rate than standard Bluetooth. This results in superior audio fidelity and allows for seamless integration with Apple AirPlay 2 and UPnP, ensuring your music sounds exactly as the artist intended.
Fusion Digital Signal Processing (DSP)
This system uses advanced DSP technology to optimize the audio signal for your specific boat environment. By using the Fusion-Link app, you can select preconfigured profiles for your speakers and amplifiers. The integrated feed-forward limiter anticipates audio peaks and adjusts gain on the fly, virtually eliminating distortion at any volume level.
PartyBus™-Network Connectivity
Designed for the modern boater, PartyBus technology allows you to connect multiple Apollo Series stereos together via Ethernet or Wi-Fi. In Party Mode, you can play the same perfectly synced source across the entire boat. In Personal Mode, the MS-SRX400 functions as a standalone zone, allowing you to listen to your own music without interrupting the "party" in other areas.
Compact True-Marine™ Design
Built to withstand the harshest marine conditions, the MS-SRX400 features an IPX6 and IPX7 water-resistant front panel. Its compact form factor and 2.7-inch optically bonded color LCD make it ideal for installation in tight spaces or as part of a sleek glass helm configuration. The optically bonded screen prevents fogging and ensures track info and album art remain visible in direct sunlight.
