• Rugged (IP67-rated) design to withstand the elements, with all buttons sealed behind a watertight membrane
• Bright and easy-to-read 2.8-inch (71 mm) full-colour LCD with a high-contrast design for enhanced viewing while in motion
• Onboard AMP powers up to 100 watts  (25-Watt RMS x 4) of dazzling sound
• Control 3 main audio zones, each with a dedicated subwoofer output
• Intuitive interface with backlit controls for easy operation day or night
• Independent settings for day and night lighting with separate brightness controls for the display, buttons and optional wired remotes
• Certified NMEA 2000 network connectivity for use with multifunction displays

POWERFUL AUDIO OUTPUT
The robust audio output options include a built-in 100-watt amplifier (25-watt RMS x 4 channels) plus 9 channels of audiophile-quality preamp outputs from 3 separate audio zones, each with a dedicated subwoofer output.

THREE MAIN AUDIO ZONES
The stereo’s high-fidelity sound is deployed via 3 separate audio zones, each with its own independent control options and subwoofer output, with built-in, selectable low-pass crossover.

EASY-TO-READ DISPLAY
The MM55 stereo’s bright 2.8-inch full-colour LCD display features separate day/night themes for clear visibility in all lighting conditions. While in motion, you’ll appreciate the intuitive user interface and oversized, illuminated control knob along with the large backlit buttons. Volume, tone (bass, midrange, treble) and balance can all be adjusted separately — or linked with zone 1. Max volume levels can be set for each zone.

SIMPLE ZONE LEVEL CONTROL
The RCA zones feature the JL Audio zero-clipping circuit design with self-limiting tone controls to help prevent speaker damage at high listening levels.

MODERN MEDIA CONNECTIVITY
All the digital and analog media formats come alive on the MM55 stereo. It includes an AM/FM tuner1, Bluetooth® connectivity, USB connections with charging for USB drives or iPhone® devices plus 2 auxiliary RCA inputs — all designed to ensure nonstop enjoyment of the soundtracks to all your adventures.

REMOTE CONTROL OPTIONS
Wired and wireless remotes (sold separately) are available to add convenient auxiliary control functionality to your MediaMaster stereo. There’s even an app that lets you enjoy untethered control from your compatible smartphone or mobile device.
