About the JL Audio MediaMaster 50
A rugged receiver for outdoor fun
A rugged receiver for outdoor fun
High-performance componentry, marine-rated construction, and smart design make JL Audio's MediaMaster 50 digital media receiver the ideal centerpiece of your powersports audio system. With a digital AM/FM tuner, built-in Bluetooth® connectivity, USB and AUX inputs, and an easy-to-use interface, it's ready for the water or the trail.
Designed for great sound
The first thing that comes to mind when you think about JL Audio is sound. That's also the first thing JL Audio engineers think about, which is why the MM50 features a 100-watt amp, a 3-band EQ, and built-in high- and low-pass crossovers. The result is superb sound for boats, ATVs, UTVs, or other weekend fun machines.
Three zones for more control
With separate audio zones, the MM50 gives you great sound and the flexibility you want when you're crafting the sound on a boat. You can control the zones together or individually using JL Audio's Level Control Mode. Use two of the zones for your speakers and another for a subwoofer, or just build your system in steps. You can rename each zone and even name the MM50 itself, so you'll recognize it easily on your connected devices.
All the modern media
You won't find a CD player in the MediaMaster MM50, just lots of ways to get the most out of your digital music collection. In addition to an AM/FM tuner, the MM50 offers a wide range of ways to connect external devices. Here are all the ways you can crank your tunes:
• Bluetooth® v2.1 audio streaming;
• USB 2.0 direct-digital connection for your iPhone® or USB storage device;
• AUX input for connection to a wide range of audio sources
• A NMEA 2000 direct connector makes it easy to integrate the MM50 with the rest of your NMEA 2000-compatible marine electronics (sold separately), making your receiver the hub of your system.
JL Audio designed the MM50 to excel in the outdoors. Marine-grade components and IPX66-rated weatherproofing ensure long life, but when you look at this receiver, you can tell it was designed by people who know what it's like to change music sources in choppy water or on a rough piece of road.
A keen understanding of real-world ergonomics went into the display, which features an intuitive interface with large text that's easy to read while you're in motion. The big, bright, full-color 2.8" display offers adjustable day/night lighting modes that will give you the level of brightness that works best for you. And, of course, the sleek black exterior looks really cool.
If you need more ways to control the sound around your boat, you can add optional JL Audio MediaMaster remotes.
Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.
iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

This source unit offers advanced audio features, specifically tailored to marine applications. A rubber face cover is included to put over the front-panel when its not in use for greater protection.
Note: While the MM50 is designed to be water-resistant, it should never be submerged under water or subjected to high-pressure water spray. Do not install the remote in areas of extreme heat.
2.8" LCD & Backlit Controls: The JL Audio MediaMaster MM50 features a high-brightness, full-color 2.8" LCD screen (320x240), a rotary control knob, and large push-buttons for ease of use in marine applications. The LCD offers Day/Night lighting modes with user-defined display brightness & themes. You can also adjust the brightness of the backlit rotary knob and push-buttons. The marine source unit's intuitive interface is easy to see and use while in motion on the water.
NMEA 2000 Compliant: The MediaMaster MM50 is NMEA 2000 compliant and is compatible with a range of the world's leading Multi-Function Displays (MFD) for on-screen audio control; creating a centralized control station for your boat and a more user-friendly experience. NMEA 2000 is the most popular marine standard for data communication within boats, watercrafts, and vessels. When connecting the MM50 with a NMEA 2000 supported Chartplotter or Fish finder, you bring your music to the big screen, allowing you to keep an eye on the charts or the fish while skipping tracks or adjusting the volume at the same time. Connection to a NMEA network requires NMEA 2000 cables & connectors (sold separately).
Mounting Options: The MediaMaster MM50 marine source unit requires a rectangular cutout in the bulkhead for inserting the chassis. Four screws (supplied) fasten the unit against the mounting surface, and hold the waterproof gasket against the bulkhead. A cardboard template is supplied to assist you with the cutout and drilling the screw holes.
- Chassis Size (Cutout): 3.665" (w) x 3.045" (h) x 4.0" (d)
- Front-Panel Dimensions: 4.665" (w) x 3.765" (h) x 1.25" (d)
- Screw Hole Spacing: 4.195" (w) x 1.945" (h)
Note: The receiver does not include a mounting sleeve or ISO-mount screw holes to accommodate standard I-, J-, or E-sized automotive installation.
Low Voltage Alert: A built-in alert notifies you when the +12VDC supply voltage drops below 10 volts. If triggered, the unit will enter "Safe Mode" and mute audio output. A warning will also display on-screen with instructions to turn the unit off until normal operating voltage is restored.
Optional Remote Control: Wired and NMEA 2000 remote control options are available for the MM50 marine source unit.
- Wired Remote: Connect an optional MMR-20-BE Wired Remote (13699921, sold separately) to add remote control functionality from extended locations (up to 3). You will also need a remote control extension cable (13699905, sold separately). If you are connecting more than one wired remote, you will need a 2-way splitter (13699908, sold separately).
- NMEA2000 Remote: The MMR-40 (13699910, sold separately) is a NMEA 2000 network remote controller designed to add full-function, auxiliary control to the MediaMaster MM50 source unit. The MMR-40 can be connected to a MediaMaster source unit through an established NMEA 2000 network (NMEA 200 cables and connectors sold separately), or a "closed" network using JL Audio's Powered Network Cable (13699928, sold separately). It will automatically recognize the connected host MM50 source unit. All host source unit controls and screen info are then mirrored onto the MMR-40's full-color, 2.8" LCD screen.

Audio output options for each zone include an onboard amplifier for powering up to four speakers, as well as six channels of 4V preamp outputs for the two main zones and a dedicated subwoofer zone. Each zone has its own flexible audio options and is controlled by a configurable master volume knob for quick, on-the-fly level adjustments, giving you complete command of volume levels in different areas of your boat. All zones also utilize a zero-clipping audio circuit, with self-limiting tone controls to prevent speaker system damage.
Built-In 25W x 4Ch Amplifier: A built-in amplifier generates 100 watts of high-fidelity output (rated at 25 watts RMS x 4 channel) to power two main zones.

Tone Controls: You can set independent Bass, Midrange, Treble, and Balance controls for each zone. Or, you can link the same tone controls to both zones.
Level Control Modes: Level Control Mode delivers on-the-fly volume adjustments of all zones, together or individually.
- Variable: The volume knob adjusts all zones simultaneously, with independent control of each zone's relative offset level
- Fixed: Sets the output level of selected zones at a specific output voltage (4V, 2V or 1V RMS) that is not affected by the volume control
- Off: Disables the output level of selected zones.
Note: The head unit's volume range is -62 to 0.
Volume Limit: Volume Limit allows you to set a custom, maximum allowable volume level for each zone. The head unit's volume range is -62 to 0.
Rename Zone: You can create your own names for each zone or choose from preset names (Bow, Bridge, Cabin, Cockpit, Galley, Helm, Stateroom 1, Stateroom 2, Tower, Transom).
