EASY-TO-READ DISPLAY
The MM55 stereo’s ultrabright 2.8-inch full-color 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.
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. 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
On-the-fly level controls make adjusting audio zones a breeze — while the unit’s volume limit feature ensures that nobody gets blasted inadvertently. 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.
