Product Description

Features & Specifications



JL Audio MMR-20-BE MediaMaster Wired Remote Controller #99921

The JL Audio MMR-20-BE MediaMaster Wired Remote Controller is the perfect way to control your audio system. The MMR-20-BE gives you complete control over your audio system, allowing you to change settings and manage playback with ease. It features a backlit LCD display that makes it easy to see what’s going on, even in low light conditions. Plus, the included RF transmitter means you can place the controller anywhere in your room without having to worry about running wires.
Connecting an optional JL Audio MMR-20-BE Wired Remote Controller will add auxiliary control functionality from extended locations, such as separate audio zones throughout a vessel. Up to three remotes may be connected to a single MediaMaster MM100-BE at a maximum distance of 75 ft.

LED Source Indicators

Blue LED indicators on the front of the remote controller are used to report the currently selected source. Pressing the button will cycle through each source option (RADIO/USB/Bluetooth/AUX).
Since the JL Audio MMR-20-BE does not incorporate a display screen, all available tuner options (AM/FM/WB/SiriusXM) are combined as “RADIO”. When RADIO is chosen, the last tuner used will be selected. To change tuners, use the MediaMaster source unit.

Control Functions

Below is a list of the JL Audio MMR-20-BE command functions.  The functionality of some controls will vary depending on the current source and/or last tuner selected. Note: The MediaMaster source unit only accepts commands from the MMR-20-BE when its display is on a “Now Playing Screen” or in the “SOURCE: Select” menu screen.
