What makes the MS-RA770 unique is the wi-fi connection, the touchscreen interface, and the PartyBus Network. To really take advantage of the MS-RA770 you need to have a wifi connection on your boat. The Wi-Fi connection is what allows Apple AirPlay 2 to function and it is what enables the Fusion PartyBus network.
If you don't have Wi-fi, you can probably get all the functionality you want and need from a less expensive unit.
The Fusion PartyBus Network allows you to connect and control multiple Fusion radio from the MS-RA770. You can create multiple "Groups" where the audio from one head unit is synchronized and played across all head units, some head units, or just the RA770, depending
on how you have your groups setup, and how many groups you have. With PartyBus, you can turn other radios on and off and control the volume of the other radios. There is also a "Home Zone" feature which is where the actual MS-RA770 is located. With this, when audio is changed in another zone, it will default back to the control
of the home zone after a period of inactivity. All of this functionality requires each unit to be connected to the wi-fi network. You will need the Fusion Link app as well to join or quit the PartyBus from one of the remote radios.
The Built in DSP in the MS-RA770 optimizes the audio signal the remove distortion and equalize volume. You can create profiles for the environment and each speaker so that you have customized output the deliver the right frequencies to the right speakers, given the environment. The sound profile you want outside
is going to be different than the sound profile you want in the cabin. With the built-in DSP in the RA770, you can customize this to your needs
The MS-RA770 offers versatile mounting options. The chassis of the radio will fit a standard DIN size opening. If you have a customized, glass helm, you could also mount the RA770 flush for a seemless integration. This would only show a protruding volume button
and everything else would sit flush.
