JL Audio Volume Controller for MediaMaster Source Unit with NMEA 2000 Network Connectivity (MMR-5N2K)

The MMR-5N2K is a wired remote designed to add auxiliary volume control to compatible MediaMaster source units. Outfitted with a NMEA 2000 Micro-C connector, the MMR-5N2K 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 to single MediaMaster source unit using MMC-PN2K powered network cables (sold separately) to simulate an isolated, stand-alone NMEA 2000 network

Features

• NMEA 2000 Certified (LEN 2): Ensures seamless integration with NMEA 2000 networks for reliable communication.
• Weatherproof Design (IPX7 Rated): Built to withstand marine environments, providing durability against water exposure.
• Large Rotary Control: Facilitates easy volume adjustments, especially while in motion.Simultaneous Audio Zone
• Adjustment: Single knob controls all audio zones concurrently for unified sound management.
• Push-Button Mute/Unmute: Allows quick silencing or resumption of audio with a simple button press.
• Integrated LED Ring: Features programmable brightness for visibility and aesthetic appeal.
• Compact Installation: Requires only a single 1.5-inch (38 mm) hole for front-mounted setup.
• Automatic Source Unit Recognition: Identifies connected MediaMaster source unit models for optimized functionality.
