What customers say
The Fusion Apollo MS-RA770 is widely regarded as the benchmark for premium marine audio, earning high praise for its exceptional sound quality.

Know before you buy
Yes, the MS-RA770 supports four independent audio zones. You can adjust volume levels, balance, and source settings for each zone separately through the touchscreen interface.
PartyBus functionality works over Ethernet, meaning you will need to hardwire your Fusion-enabled devices together to sync audio across the entire vessel. This ensures a stable, high-quality connection without the latency issues sometimes found in wireless setups.
DSP allows you to customize the audio settings based on your specific speaker setup and the environment of your boat. By selecting your Fusion speakers and environment in the app, the system automatically calculates the optimal settings for the best possible sound reproduction.
The 4.3-inch display is optically bonded, which significantly reduces glare and prevents fogging. This construction ensures the screen remains vibrant and legible even in bright, outdoor marine conditions.
A physical remote is not included, but you don't necessarily need one. You can control the system directly via the touchscreen, or use the Fusion-Link app on your smartphone or compatible Garmin multifunction display.
Yes, the MS-RA770 supports over-the-air software updates. As long as the unit is connected to a WiFi network, you can download and install the latest firmware updates directly through the stereo's interface.
