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.

Audio output options include a rock-solid, onboard amplifier, capable of powering your speakers with 100 watts (25W RMS x 4 @ 4 ohms) of break-through sound, as well as six channels of audiophile-quality preamp outputs from two independent main zones, plus a dedicated subwoofer zone. 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.

With certified NMEA-2000® connectivity, the MM100s-BE is also an ideal partner to your Garmin, Lowrance, Raymarine or Simrad Multifunction Display! (MFD)
