{"product_id":"jl-audio-r5-marine-volume-controller-nmea-2000","title":"JL Audio R5 Single Stereo Volume Controller","description":"\u003cp class=\"nvn-hero\"\u003eThe JL Audio R5 is a rugged single-knob volume controller that wires straight into your boat's NMEA 2000 network. One dial sets master volume across every audio zone on a compatible JL Audio head unit, and a push of the knob plays or pauses. IPX7-rated and built for the helm.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe JL Audio R5 is a single-knob volume controller built for one job and built to do it well. Mount it on your dash, wire it into your boat's NMEA 2000 network, and you've got tactile control over every audio zone running off a single head unit. Turn the knob to set the level. Push it to play or pause. That's the whole interaction, and out on the water that simplicity is exactly what you want when your hands are wet and the chop is picking up.\u003c\/p\u003e\n\u003cp\u003eHere's the part that makes this controller different from a generic volume dial. It talks to your stereo over NMEA 2000, the same network backbone your chartplotter and other instruments already ride on. One Micro-C connector, one T-connector into the trunk line, and the R5 is live. There's no separate power run to fish through the dash and no RCA pass-through to worry about at the knob itself. The controller pulls its power and its data straight from the network, which keeps the wiring behind your console clean and keeps troubleshooting simple down the road.\u003c\/p\u003e\n\u003cp\u003eInstallation is about as friendly as marine electronics get. You need a single 1.5-inch hole for a front-mount fit, and the R5 drops right in. Two screws are in the box along with the T-connector you'll need to tap the network. The whole face measures 2.35 inches square and sits 2.04 inches deep behind the dash, so check your clearance before you cut. Older center consoles with shallow dash pockets can be tight, so measure twice. If depth is marginal, a recessed or spacer install sorts it out.\u003c\/p\u003e\n\u003cp\u003eThis thing is rated IPX7, which means the control surface shrugs off spray, rain, and the occasional wave over the bow when it's mounted properly. Operating range runs from 32 to 122 degrees Fahrenheit, so it's happy from a cold spring launch to a July afternoon offshore. JL Audio also publishes a compass-safe distance of 3.94 inches, worth keeping in mind if you're mounting near a magnetic compass. And because salt is the enemy of every helm control, a dab of dielectric grease on the shaft at install time is cheap insurance against salt creep over the seasons.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anybody running a compatible JL Audio marine head unit who wants a clean, dedicated volume control at a second helm, at the transom, or up on a tower where reaching the main stereo isn't practical. It shines in multi-zone boats. Say you've got cockpit speakers, tower speakers, and a cabin pair all running off one source unit. The R5 gives you master volume over all of them from wherever you mounted it. That makes it a natural fit for a second station on a center console or a control point back at the swim platform.\u003c\/p\u003e\n\u003cp\u003eA couple of honest notes. The R5 is a controller, not a stereo. It doesn't play music on its own and it won't add zones your head unit doesn't already support. It's also a wired NMEA 2000 device, so it pairs with a compatible JL Audio source unit rather than any random aftermarket stereo. And it doesn't carry its own illumination wire, so if you run a fully blacked-out helm at night, plan to light it from a nearby backlit panel. None of that is a knock. It just means you'll get the most out of it when it's matched to the right system.\u003c\/p\u003e\n\u003cp\u003eBottom line, if you've already got a JL Audio marine stereo and you want rugged, no-nonsense volume control somewhere the main unit can't reach, the R5 is the piece that ties it together. One knob, one hole, one connector, and you're done.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eSingle-knob control adjusts all audio zones of one head unit, so master volume lives under a single dial\u003c\/li\u003e\n  \u003cli\u003eConnects over NMEA 2000 with one Micro-C connector, sharing the network already running at your helm\u003c\/li\u003e\n  \u003cli\u003ePush-button play and pause built into the knob for quick control without reaching the stereo\u003c\/li\u003e\n  \u003cli\u003eIPX7-rated control surface handles spray, rain, and wash-down at the helm\u003c\/li\u003e\n  \u003cli\u003eCompact 2.35-inch square face fits tight second-station and tower mounts\u003c\/li\u003e\n  \u003cli\u003eFront-mount install needs just a single 1.5-inch hole, and two screws are included\u003c\/li\u003e\n  \u003cli\u003eLow 110 mA max current draw pulls power straight from the NMEA 2000 network, no separate power run\u003c\/li\u003e\n  \u003cli\u003eWide 10.8 to 16 VDC input range suits standard 12-volt marine systems\u003c\/li\u003e\n  \u003cli\u003eOperating range of 32 to 122 degrees Fahrenheit for cold launches to hot offshore days\u003c\/li\u003e\n  \u003cli\u003eIncludes a T-connector for the network and two mounting screws in the box\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized JL Audio reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the JL Audio R5 control?\u003c\/summary\u003e\n    \u003cp\u003eIt's a single-knob master volume controller for one compatible JL Audio marine head unit.
