JL Audio MMR 40 NMEA 2000 Network Controller - Full Color LCD Display & MediaMaster Compatibility | Marine Audio System Control for Boats & Yachts

The MMR-40 is a NMEA 2000® Network Controller engineered to add full-function, auxiliary control to MediaMaster® source units.

• Outfitted with a NMEA 2000® Micro-C connector, the MMR-40 connects to a host MediaMaster® source unit in two ways:
• Direct interface with a vessel's NMEA 2000® network using applicable NMEA 2000® cables and connectors (not included)
• Direct connection of one MMR-40 with one host MediaMaster® source unit using MMC-PN2K powered network cables (sold separately) to simulate an isolated, stand-alone NMEA 2000® network

Once connected, the MMR-40 automatically recognizes the host MediaMaster® source unit and will then mirror all host source unit controls and screen info onto the MMR-40's full-color, 2.8-inch LCD display, resulting in a complete MediaMaster® user experience.

The MMR-40 is equipped with independent display theme and lighting controls for maximum mounting location flexibility, regardless of the settings on the host source unit. Engineered for real-world marine (and many outdoor) applications, its weatherproof (IP66 rated) chassis is built to withstand the harshest environments.

The MMR-40 includes the following features:

• NMEA 2000® Certified (LEN 4)
• Easy-to-read, high-brightness, 2.8-inch full-color LCD display with large backlit controls
• Independent day/night display themes and lighting controls
• IP66 rated for real marine duty
• Protective Sun Cover included
