The JL Audio R5 is a rugged, ultra-compact wired marine volume controller engineered by Garmin. It is built specifically to give boaters quick, tactile control over their music without needing a giant radio cutout on the dashboard. It works as an accessory dial for next-generation marine stereos like the JL Audio A60 and A60-H hideaway units.
Here is the complete description and technical breakdown for this unit.
The JL Audio R5 is designed for simple, "blind" audio adjustments while your boat is bouncing on choppy water. Instead of tapping a touchscreen or hunting for tiny buttons, you can easily grab the oversized rotary dial to change the volume.
The device features a clean, minimalist design that fits into tight spaces on your dash. It is also perfect for adding secondary control points around your boat—such as near the swim platform, inside the cabin, or on a flybridge. A built-in button allows you to pause the music instantly with a simple press.
-
Tactile System Interface: Features a single, oversized rotory volume dial paired with a center-push button. Turning the knob changes the volume, while pushing the knob instantly switches between Audio Play and Audio Pause.
-
Global System Control: Modifies the output level of all active audio zones simultaneously. This lets you raise or lower the volume across the entire vessel at the exact same time.
-
Network Integration (NMEA 2000): Built as a native NMEA 2000 certified device. It plugs directly into your boat's electronic network backbone and comes packaged with a standard NMEA 2000 T-connector for plug-and-play installation.
-
Power Source: Draws its minimal operating power directly from the NMEA 2000 network bus lines. It does not require a separate 12V power wire run back to the battery or fuse block.
-
Marine Ruggedness: Rated with an IPX7 waterproof armor rating. The chassis is heavily sealed against direct water spray, rain, continuous UV sunlight exposure, salt fog, and brief submersions.
-
Physical Dimensions: Ultra-compact footprint that saves valuable dash space. It requires a tiny 1.5-inch diameter hole cutout for flush-mount installation.
-
Low-Light Visibility: Equipped with built-in LED backlighting behind the control ring, making the dial easy to find and use during nighttime navigation.
-
System Compatibility: Specifically engineered to pair with next-generation Garmin-era JL Audio marine electronics. Note that it is not compatible with older legacy JL Audio MediaMaster series head unit
