JL Audio MMA-1-HTML Marine HDMI Interface for MediaMaster 010-03135-00 (99956)

JL Audio MMA-1-HTML is a marine-grade HDMI® interface module designed to bridge external video sources to supported MediaMaster® source units and compatible multifunction displays (MFDs). It enables clean digital A/V routing in modern helm architectures where accessory cameras, streaming devices, and chartplotters must share video paths without generic adapters or non-marine cabling.

Built for real marine duty, the MMA-1-HTML uses a lockable panel-mount HDMI port for the vessel side, a short secure pigtail for bulkhead penetration, and a compact electronics module for signal management. When paired with JL Audio MediaMaster systems, it supports application-specific video workflows such as mapping overlays, camera feeds, and HDMI media devices while maintaining OEM-plus installation quality.
