JL Audio MMR-20 BE Marine Audio Remote Control

The JL Audio MMR-20 BE is a wired remote control without a screen, designed to extend the control functionality of JL Audio MediaMaster® marine source units. It allows you to manage essential audio functions of your system from an auxiliary location.

Main features of the MMR-20 BE include:

Water-resistant design with IP67 certification.No-screen auxiliary control for MediaMaster® source units.Blue LED indicators for the selected audio source.Adjustable backlight brightness via the source unit.Easy installation with a 50 mm (2 in) hole and adjustable C-clamp bracket.

Yes, the MMR-20 BE remote control is designed to be water-resistant with IP67 certification. This means it can withstand immersion in water up to 1 meter deep for 30 minutes, provided it is installed correctly. However, it must not be submerged for extended periods or exposed to high-pressure water jets.

The MMR-20 BE remote is specifically designed to be compatible with JL Audio MediaMaster® source units.

You can connect up to three MMR-20 BE remote controls to a single MediaMaster® source unit.

To connect the MMR-20 BE remote control to your MediaMaster® source unit, extension cables (available in 6 ft or 25 ft lengths, models MMC-6 and MMC-25) are required and sold separately. If you wish to connect multiple remote controls to a single source unit, a Y-splitter (model MMC-2Y) is also required and sold separately.

Each MMR-20 BE remote control can be connected up to a maximum distance of 22.8 meters (75 feet) from its source unit using the appropriate extension cables.

A 50 mm (2 in) diameter hole is required for installing the MMR-20 BE remote control. Sufficient access to the rear of the panel is also necessary for securing the hardware.

The mounting hardware included with the MMR-20 BE remote allows installations on flat panels with a maximum thickness of 38 mm (1.5 inches).

The MMR-20 BE remote control package includes:

One MMR-20 BE wired remote control.One lip seal (pre-installed).One flat gasket (optional).Two stainless steel threaded studs.Four 7 mm stainless steel nuts.Four stainless steel washers.One C-shaped aluminum bracket.One user manual.

Yes, it is recommended to apply a sealing compound (not included) on the threaded studs before inserting them at the rear of the MMR-20 BE and before installing the final nuts and washers to ensure optimal watertightness.

The C bracket is designed with break lines that allow you to remove sections of the flange to adjust the mounting panel thickness. To remove a section, use pliers and bend it back and forth along a break line until it separates. Be cautious of sharp edges and file if necessary.

The MMR-20 BE remote offers the following control functions:

Power the source unit on/off (short/long press).Browse audio sources (RADIO/USB/Bluetooth®/AUX).Increase and decrease volume.Mute audio (AM/FM/WB SiriusXM®/AUX).Pause or resume playback (USB/Bluetooth®).Select next/previous favorite (AM/FM/WB SiriusXM®).Select next/previous track (USB/Bluetooth®).Fast forward/rewind (USB, by holding the button).

The MMR-20 BE remote control uses blue LED indicators on its front panel to show the currently selected audio source. Pressing the source selection button cycles through the options (RADIO/USB/Bluetooth®/AUX).

Yes, the LED and button brightness settings on the MMR-20 BE remote can be adjusted. These settings are accessible via the system settings menu of the MediaMaster® source unit and can be configured independently for day and night lighting modes.

No, the MMR-20 BE remote is an auxiliary controller without a display screen. It uses LED indicators to show the selected source.

Since the MMR-20 BE does not have a display, all available tuner options (AM/FM/WB SiriusXM®) are grouped under the generic 'RADIO' option.

Yes, several safety precautions must be observed:

Do not install the remote control in areas of extreme heat. Ensure it is securely mounted to prevent loosening due to shock or vibration. Check for fuel tanks, gas/brake lines, wiring harnesses, or other critical systems behind the panel before drilling. Secure all wiring with cable ties or clamps to protect it from moving parts and sharp edges.

For USB and Bluetooth® sources, a short press of the appropriate button allows you to pause or resume playback. To select the next or previous track, a short press of the corresponding buttons is used. For fast forward or rewind, you must hold the button down (USB source only).

Although it is a marine audio remote control, the MMR-20 BE is designed for marine and all-terrain environments, making it suitable for various applications requiring water resistance and robust auxiliary control.
