JL Audio Media Master MM100S digital media receiver

Control four audio zones with one receiver

The accent is on great audio

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 sound

With four audio zones, the MM100S lets you build the system you want for your boat. 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, 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 offers a wide range of ways to connect external devices. Here are all the ways you can crank up the tunes through your MM100S:

• 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-compliant CAN bus lets you connect to compatible marine electronics (sold separately), making your receiver the hub of your system.

Real-world usability

JL Audio designed the MM100S 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. And 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.

If you need more ways to control the sound around your boat, you can add optional JL Audio MMR-20 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.

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 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 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).

    Note: NMEA 2000 Compliance will require a future firmware upgrade (no ETA).

    Mounting Options: The MediaMaster M100s 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)

    • Screw Hole Spacing: 5.305" (w) x 1.965" (w)
    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 Wired Remote Control: Connect an optional MMR-20 Wired Remote (13699907, 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).

    • Not compatible with older iPod/iPhone devices which feature a 30-pin connector.
    • Apple iPod/iPhone software updates may change functionality results. If you download a newer software version, you may need to reset the head unit and your iPod/iPhone to regain functionality. If this doesn't work, you may need to wait until a newer software update is available.

    Built-In AM/FM/Weather Band Tuner with RDS: The MediaMaster 100s is equipped with a digital AM/FM tuner with NOAA weatherband capability. RDS (Radio Data System) displays channel, category, and program information for select FM broadcasts (where available). You can store up to 18 AM/FM/WB presets in any combination.

    Audio Section

    8Ch/4V Pre-Outs: The JL Audio MM100s is equipped with audiophile-quality, preamp-level audio circuits, deployed in an 8-channel architecture with 4V RMS outputs. The MM100s is equipped with four sets (8ch) of low-voltage, line-level RCA outputs (4V) to send audio signals to your external marine amplifiers. Each output pair delivers full-range, low-distortion audio, arranged into four zones.

    Note: This marine source unit does not feature a built-in amplifier. You will need to connect external amplifier(s) to this unit's pre-outs to power your marine speakers.

    Multi-Zone Configuration: The JL Audio MediaMaster 100s offers excellent system control flexibility in a wide range of marine audio system configurations.

    • Main Audio Zone 1 features bass, midrange, treble and balance controls.
    • Audio Zone 2 is a full-range zone with independent bass, midrange, treble and balance controls, plus absolute or relative volume control.
    • Audio Zone 3 can be assigned as a Subwoofer Zone or as a 3rd Full-Range Zone with independent bass, midrange, treble, balance controls, plus absolute or relative volume control.
    • Audio Zone 4 is a fixed level zone that can be set to 1V, 2V, or 4V.

    Note: Zones 1-3 feature a zero-clipping audio circuit design, with self-limiting tone controls to prevent speaker system damage.

    Start Up Volume: This setting determines the volume level when the unit is turned on and can be useful in preventing sudden output bursts. You can set a separate start up volume for Zone 1, Zone, and Zone 3.

    Relative or Absolute Volume: You can select either Relative or Absolute for the volume control of Zones 2 and 3, in relation to Zone 1.

    • Relative: This setting is used to link the output level of Zone 2 and/or Zone 3 to the volume level of Zone, so all three zones play at the same "relative" volume level.
    • Absolute: When selected, the output level of Zone 2 and/or Zone 3 will be independent of each other and Zone 1, so you can have different Zones playing at different volume levels.
    Note: The head unit's volume range is -62 to 0.

    Tone Controls: You can set independent Bass, Midrange, Treble, and Balance controls for Zones 1, 2, and 3.

    Customer Q&A

    5 questions already asked

    Will the MM100s control an itouch (4th generation connected by 30 pin to usb cable) connected to the usb input? Only need basic function, such as play, pause and skip funtions. The manual only references i-phone compatibility, but does makes vague reference to digital media. Specifics would be great (ie. supports itouch and these file types...). Thanks.

    "Note: Not compatible with older iPod/iPhone devices which feature a 30-pin connector." You will find this information, and more, by clicking the "Details" tab on the unit's main webpage and scrolling down below the "Features & Specs" table. While I know this isn't the answer you were looking for, I hope the information helps. My Bio:

    Yes the protective cover is included.

    do they make a cover plate to adapt from a standard size stereo to the Media Master? Preferably a Billet adapter plate?
    [ Colin M  Jul 17, 2016 ]
    1 answer
    No. The MediaMaster comes with it's own trim ring but there are no pre-fabricated adapters for custom installation into to standard single or double DIN stereo opening. The MediaMaster requires a cutout that is: 4.685" (w) x 3.205" (h) x 3.205" (h) x 3.255" (d) I hope that helps! My Bio:
