ADD A SUPER SOUNDTRACK TO YOUR OUTDOOR FUN
Engineered to deliver outstanding audio fidelity and advanced performance features on your boat or powersport vehicle, the compact MediaMaster 55 digital stereo puts amazing sound at your fingertips for any outdoor adventure. A hideaway receiver, MM55-HR, is also available, offering all the features of MM55 — minus the LCD display and physical controls.
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.
