Built for marine (and powersports) applications, MediaMaster is a full-featured, weatherproof marine source unit with a full color LCD display. Its rugged, weatherproof (IP66 rated) chassis houses an ultra-bright, 3.5 inch full-color LCD display, with separate Day/Night lighting themes to keep things easy-to-see at all times. An intuitive user interface with big, legible text and large backlit controls makes it easy to use, especially while in motion. Equipped with audiophile-quality circuits, 8-channels of preamp outputs deliver crystal-clear signals into four separate audio zones. Each zone is outfitted with its own set of independent control options, creating a versatile audio command center, configurable for a wide range of system or vessel types, from basic, to multi-location, with selectable subwoofer control. Zones 1-3 include a zero-clipping audio circuit design and self-limiting tone controls to help prevent speaker system damage. The MM100s-BE features a Digital AM/FM/Weather Band Tuner, Bluetooth connectivity, separate line-level AUX and USB/iPhone inputs, and it's SiriusXM-Ready, too. Connect an optional MMR-20 Wired Remote (sold separately) to add remote control functionality from extended locations (up to 3). With the MediaMaster 100s-BE, you can enjoy great sound wherever your adventures might take you.
