JL Audio Weatherproof Source Unit With Full-Color LCD Display - MM105



Scheduled Delivery

MediaMaster® 105 - Premium, weatherproof marine source unit with full-color LCD display 

Enjoy great audio wherever your adventures might take you, with the MediaMaster® 105, a Premium Source Unit designed to withstand anything Mother Nature can dish out. This full-featured source unit delivers top-flight sound performance and advanced audio features specifically designed for marine and powersports applications. Its rugged, weatherproof (IP67 rated) chassis houses an ultra-bright, 3.5-inch full-color LCD display, with separate Day/Night lighting themes for outstanding visibility, even in bright sunshine. When in motion, you will also appreciate the clean user interface with big text and large backlit controls.

Because sound quality is our top priority, the MM105 is not equipped with an internal amplifier designed to drive loudspeakers directly. Instead, it offers twelve channels of audiophile-quality, preamp level outputs to deliver crystal-clear signals to high-quality marine amplifiers. These are deployed via four configurable, nameable audio zones, each with its own set of independent control options, making the MM105 adaptable to a wide range of system types. On-the-fly, level controls make adjusting each or all audio zones a breeze, while a useful volume limit feature ensures that nobody gets blasted inadvertently. All zones feature our Zero-Clipping audio circuit design, with self-limiting tone controls to keep the audio clean at high listening levels, reducing the likelihood of speaker damage.
