JL Audio® MFD Data Interface for MediaMaster® Source Unit (MMA-1-HTML)

NMEA 2000® Network MFD Data Interface for MediaMaster® (010-03135-00)

Expand the control and integration of your JL Audio MediaMaster® system by projecting its user interface onto your vessel’s MFD (Multi-Function Display). The MMA-1-HTML is a sophisticated NMEA 2000® data interface that delivers seamless command and navigation of your audio system right from your helm’s display.

Key Features & Capabilities

• NMEA 2000® Certified Interface — fully compliant with industry standards to communicate across your vessel’s network. 
• MediaMaster® UI on MFD — projects the familiar MediaMaster® themed user interface onto compatible MFDs (e.g. Simrad, Lowrance, Garmin, B&G) for control at your fingertips. 
• Automatic Source Recognition — once connected, the MMA-1-HTML auto-detects the MediaMaster® source unit (e.g. MM105, MM105-HR, MM55, MM55-HR) and mirrors its functions. 
• Full System Control via MFD — control power, source selection, playback, volume, zone settings, presets, menu navigation, audio settings, and more directly from your helm display.
• Low Power Draw & Wide Voltage Range — operates efficiently with a max draw of ~150 mA and supports input voltages from 10 V to 15.9 V DC. 
• Rugged & Marine-Ready — designed to withstand harsh marine environments, with operating temperature range from –20 °C to +65 °C (–4 °F to +149 °F). 
• Compact Dimensions — measures approximately 172 mm × 101 mm × 44 mm (6.77″ × 3.98″ × 1.73″) for discrete installation. 
• Connectivity — includes a NMEA 2000® Micro-C connector (LEN 1). Ethernet & USB connectivity options support integration with your system architecture. 
• Standalone / Simulated Network Option — if your vessel lacks a full NMEA 2000® backbone, you can use an MMC-PN2K powered network cable to simulate a standalone NMEA 2000® network. 

Why Choose the MMA-1-HTML?

The JL Audio MMA-1-HTML bridges your marine audio system with the vessel’s electronics, giving you unified control from your helm. Instead of switching between your MFD and audio controls, you get full MediaMaster® functionality in one intuitive interface. Whether you're piloting or adjusting your audio settings, the MMA-1-HTML ensures your experience is seamless, clean, and efficient.

Compatible source unit models: MM105, MM105-HR, MM55, MM55-HR

Note: Functionality of the MMA-1-HTML is derived from the host source unit and connected MFD. The MMA-1-HTML requires connection to a NMEA 2000® network or use of a MMC-PN2K powered network cable (sold separately) to simulate an isolated, stand-alone NMEA 2000® network.
