JL Audio MMR-5N2K Volume Controller for MediaMaster

The JL Audio MMR-5N2K Volume Controller for MediaMaster gives you fingertip command over your marine audio system from anywhere on the helm or cabin. After years running boats with integrated stereo systems, proper volume control matters—it keeps you focused on navigation and safety while managing audio levels without fumbling through menus. This dedicated controller integrates seamlessly with JL Audio's MediaMaster head units, delivering the responsive, intuitive interface that serious boaters demand when precision and reliability are non-negotiable.

The MMR-5N2K is engineered for the harsh marine environment, featuring rugged construction that withstands salt spray, UV exposure, and deck spray without degradation. Its compact footprint and wired connection architecture ensure stable, noise-free operation across your boat's electrical system, eliminating the latency and dropout issues common to wireless controls in metal-hulled vessels. The tactile rotary dial provides immediate feedback, allowing you to adjust volume by feel—critical when your eyes are on the water, not your dashboard.

Boaters running JL Audio MediaMaster systems—whether you pilot a center console, express cruiser, or offshore yacht—will find this volume controller essential for multi-zone audio management and crew comfort. Installation integrates directly into your existing JL Audio harness without additional adapters or modification, making it a plug-and-play upgrade for systems already in the field. At just one pound, it mounts flush to your helm station, control panel, or cabin bulkhead, leaving your console clean and functional.
