    MediaMaster® - Full-featured, weatherproof marine source unit with full color LCD display - 25 Watts x 4 @ 4 Ω

    The MediaMaster® 50 is a high-performance, single-chassis, powered source unit, engineered to deliver outstanding fidelity and advanced audio features on your boat, UTV and many other outdoor applications.

    Equipped with a variety of mechless audio source options, the MM50 includes a Digital AM/FM Tuner, Bluetooth® connectivity, a USB connection for a USB drive or iPhone® and an Analog AUX input, all designed to ensure non-stop playback of your favorite soundtracks, no matter how bumpy the ride. A rugged, weatherproof (IP66 rated) chassis houses a 2.8-inch full-color LCD display, with separate Day/Night lighting themes for visibility, even in bright sunshine. When in motion, you will also appreciate the clean, uncluttered user interface with big text and large backlit controls.

Each zone has its own flexible audio options and is controlled by a configurable master volume knob for quick, on-the-fly level adjustments, giving you complete command of volume levels in different areas of your boat.
