About the JL Audio MM100s-BE

Jon Paul

The start of something big in boating

High-performance componentry, marine-rated construction, and boater-friendly ergonomics make JL Audio's Media Master MM100S-BE digital media receiver the ideal centerpiece of a stem-to-stern sound system that will be the envy of any marina.

The start of something big in boating

High-performance componentry, marine-rated construction, and boater-friendly ergonomics make JL Audio's Media Master MM100S-BE digital media receiver the ideal centerpiece of a stem-to-stern sound system that will be the envy of any marina.

Designed for great sound

The first thing that comes to mind when you think about JL Audio is sound. That's actually the first thing their designers thought about, too. Most receivers have a standard "chip" amplifier, but this one doesn't have a built-in amp at all. Instead, you'll find 8-channel audiophile-quality preamp-level outputs that you'll connect to your marine amplifiers. The result is superb sound on any boat, no matter the size or layout.

Four zones for more control

With four audio zones, the MM100s-BE lets you build the system you want for your boat. A user-friendly interface gives you enhanced volume control in all four four fully variable zones. Here's the setup:

  • Main Audio Zone: bass, midrange, treble and balance controls;
  • Zone 2: independent bass, midrange, treble and balance controls, plus absolute or relative volume control;
  • Zone 3: controls a subwoofer, or you can make it a third full-range zone like Zone 2;
  • Zone 4: a fixed level zone that's ideal for subs.

The first three zones feature a zero-clipping audio circuit design, with self-limiting tone controls to prevent speaker damage.

Thoroughly modern media

You won't find a CD player in the MM100S-BE, just lots of ways to get the most out of your digital music collection. In addition to an AM/FM/Weather Band tuner, the MM100s-BE offers a wide range of ways to connect external devices. Here are all the ways you can crank up the tunes through your MM100s-BE:

• Bluetooth® audio streaming with AptX® for superior sound quality and total control of play/pause and track up/down functions;

• USB 2.0 direct-digital connection for your iPhone® or USB storage device;

• SiriusXM-Ready: connect to the SiriusXM SXV300 tuner (sold separately, subscription required) to enjoy satellite radio programming when you're many miles offshore;

• AUX input for connection to a wide range of audio sources

• A NMEA 2000 direct connector makes it easy to integrate your MM100s-BE with the rest of your NMEA 2000-compatible marine electronics (sold separately), making your receiver the hub of your system.

Real-world usability

JL Audio designed the MM100s-BE to excel in the marine environment; it's not a car receiver that's been modified to simply survive in it. 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 on a dark night.

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. Big buttons and a generously-proportioned control knob fall easily to hand when you need them. The big, bright, full-color 3-1/2" display offers adjustable day/night lighting modes that will give you the level of brightness that works best for you and your boat. And, of course, the sleek black exterior will look great in your boat.

If you need more ways to control the sound around your boat, you can add optional JL Audio MMR-20 BE 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 marine digital media receiver will not play CDs.

This receiver does not have a built-in amplifier, so you'll need marine amps to power your system.

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 MM100s BE 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.

    3.5" LCD & Rotary Knob: The JL Audio MediaMaster 100s features a high-brightness, full-color 3.5" 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 MM100s BE 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 MM100s BE 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 M100s BE marine source unit requires a rectangular cutout in the bulkhead for inserting the chassis. Four screws (supplied) fasten the faceplate 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: 4.685" (w) x 3.205" (h) x 2.875" (d)
    • Faceplate Dimensions: 4.965 (w) x 3.775" (h) x 1.5" (d)
    • Trim-ring Dimensions: 5.955" (w) x 3.905" h) x 0.785" (d)
    • Cutout Size: 4.685" (w) x 3.205" (h) x 3.205" (h) x 3.255" (d)
    • Screw Hole Spacing: 5.305" (w) x 1.965" (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.

    Wiring Harness: The included wiring harness features four leads +12VDC (Red), Ground (Black), Illumination (Orange), and Amp Turn-On (Blue).

    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 MM100S BE.

    • 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 M100s BE 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.

    3 questions already asked

    Is this a newer 100 model? I heard there were many issues with the MM100 and it was discontinued? Can you clarify and advise if the MM50 was also discontinued?
    lincoln  Feb 22, 2022
    1 answer
    MM100 first came out in 2017, what we have in inventory would be the most recently produced as we just received a shipment a little over a week ago. The last shipment of MM50's we received was close to a year ago. No word from JL on either of them if they have been discontinued, but at least the MM100 is current and in stock.
