{"product_id":"qbp106415","title":"JL Audio MMR-5N2K NMEA 2000 Wired Remote Volume Controller, For JL Audio MediaMaster, IPX7","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe JL Audio 010-03134-00 is a JL Audio MMR-5N2K MediaMaster NMEA 2000 volume controller that adds an extra, networked volume knob for a compatible MediaMaster source unit. It connects via an NMEA 2000 Micro-C drop and carries an IPX7 water resistance rating (tested to 1 m for up to 30 minutes when properly installed).\u003c\/p\u003e\u003cp\u003eIt installs from the front of a flat panel and needs a single 1.5-inch (38 mm) cutout, with at least 2.35 inches (60 mm) square of flat surface for the trim ring. For wiring, it can interface with a vessel NMEA 2000 network using the appropriate cables and connectors (not included), or it can be wired directly to one MediaMaster source unit using MMC-PN2K powered network cables (sold separately) to create a small, stand-alone network.\u003c\/p\u003e\u003cp\u003eAll control comes from the connected MediaMaster. Volume changes apply across the stereo’s zones, and the knob press toggles mute and unmute, which is handy when you want quick control at the helm or in the cockpit without reaching for the main display.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eNMEA 2000 Micro-C connection for networked remote volume control with compatible MediaMaster source units\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 certified with LEN 2 for straightforward network load planning\u003c\/li\u003e\n\u003cli\u003eIPX7 water resistance rating (tested to 1 m for up to 30 minutes when properly installed)\u003c\/li\u003e\n\u003cli\u003eFront-mount panel installation with a 1.5-inch (38 mm) cutout requirement\u003c\/li\u003e\n\u003cli\u003eSingle knob adjusts system volume across audio zones; press once for mute and unmute\u003c\/li\u003e\n\u003cli\u003eWhite LED status ring for at-a-glance feedback, with adjustable brightness settings\u003c\/li\u003e\n\u003cli\u003eIntended for use with one MediaMaster source unit only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eWhat's included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eMMR-5N2K main body\u003c\/li\u003e\n\u003cli\u003eVolume knob\u003c\/li\u003e\n\u003cli\u003eTrim ring\u003c\/li\u003e\n\u003cli\u003eFlat gasket (preinstalled)\u003c\/li\u003e\n\u003cli\u003eMounting screws (2)\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis controller is made to work with JL Audio MediaMaster source units, including MM105, MM100s-BE, MM100s, MM80-HR, and MM50. It should be connected to a single MediaMaster source unit through an NMEA 2000 network (full vessel network or a stand-alone powered network cable setup).\u003c\/p\u003e\u003cp\u003eFor zone behavior, the host stereo’s zone level control mode needs to be set to Relative or Variable. Once connected, volume adjustments act across all zones together.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eMount it in a flat panel where you can reach the back side for the connector and cable routing, and avoid areas of extreme heat. Cut a 1.5-inch (38 mm) hole, position the unit with the alignment arrow at the 12 o’clock position, then mark and drill the pilot holes for the two mounting screws.\u003c\/p\u003e\u003cp\u003eAfter securing the body, press the trim ring on with the JL Audio logo oriented at the top, then install the keyed volume knob. Plan the cable path before drilling and secure wiring so it cannot chafe or move with vibration.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThe LED ring gives simple feedback during normal use: solid on indicates a compatible source is detected, a repeating two-flash pattern indicates no compatible source is detected, and a slow pulse indicates the system is muted. LED ring brightness can be set from the controller, which helps when moving between night runs and full-sun days.\u003c\/p\u003e\u003cp\u003eThis is a good match for boats where the MediaMaster head unit is mounted away from where people actually listen, such as a helm stereo with cockpit speakers, or a cabin source unit with a second control point in the cockpit.\u003c\/p\u003e\u003ch6\u003eEnvironmental notes\u003c\/h6\u003e\u003cp\u003eIPX7 water resistance covers washdowns and heavy spray when installed correctly, but it is not meant for prolonged submersion or situations that create pressure beyond its depth rating. On saltwater boats, a quick fresh-water rinse after a rough day helps keep the bezel and knob turning smoothly.\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":52256226115765,"sku":"QBP106415","price":193.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1284859_qbp106415.webp?v=1771286693","url":"https:\/\/www.qualityboatparts.com\/products\/qbp106415","provider":"Quality Boat Parts","version":"1.0","type":"link"}
