MMR-40
Marine Remote Commander for use with MediaMaster®
Overview
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-6, or MMC-PN2K-25 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" 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
Note: The MMR-40 is not a stand-alone receiver and does not function without a connected MediaMaster® source unit. All remote control functionality of the MMR-40 is solely derived from the host source unit. Functionality of the MMR-40 requires connection to a NMEA 2000® network or use of MMC-PN2K powered network cables (sold separately).
Marine Materials / Testing
The design of marine products requires extensive materials testing to achieve reliability and longevity.
Building serious marine products requires a real commitment to environmental testing and materials specification. To this end, JL Audio has invested in Ultraviolet testing chambers (to simulate years of sun exposure) and Salt Fog chambers (to simulate years of exposure to salt-water environments). This testing is critical to building products that will not only sound great in your boat, but will also sound great for many, many years.
Materials Used
- Injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated with UV inhibitors for marine duty.
- Marine-grade, synthetic fiber spiders with progressive roll designs to withstand high humidity.
- Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to prevent corrosion.
- Gold-plated, marine-grade brass connection terminals
- Marine-grade stainless steel mounting hardware is included.
