A couple of the key features that boat builders and installers are excited to incorporate into their installation are the Dual Audio Zone Capability and the Advanced Sound Contouring.

With Dual Audio Zone Capability the system creates two different volume areas on the boat which can be controlled independently, such as passenger area and tower speakers. With the GMR-LED Advanced Sound Contouring the system allows independent subwoofer level control with onboard 8-Band graphic equalizer adjustments. Another new feature to this platform is the inclusion of Weather Band access which is so often crucial in heavy weather and coastal areas.
