On board personalized audio experience

To have music all over the boat might not appeal to everyone on board at the same time. Therefore a product has been developed that will make it easier to have a personalized audio experience.
“To enjoy a stereo’s full sound in different areas of the boat, additional speakers are normally used. Poly-Planar’s new ME-50 Expansion Amplifier is designed for the boater who wants to relax on the back deck and turn up the music-all without waking a sleeping crew member or distracting the captain at the helm.”
