Product Details

JL Audio Weather Proof Bluetooth Controller/Receiver - 91127


  • Designed for marine and powersports applications, the MBT-CRX streams your favorite tunes from a Bluetooth® equipped (A2DP) device directly to your audio system with volume, track and play/pause functions.

  • With an IPX6 water resistance rating, this premium wireless audio controller / receiver is engineered to be right at home on the seas or in the back trails, and it’s unobtrusive size makes it the go-to solution for any installation requiring Bluetooth® connectivity and control. Use the stereo pair of RCA outputs to connect to any amplifier or source unit with line-level/auxiliary inputs.

  • Equipped with Bluetooth® v4.0 and the aptX® codec, the MBT-CRX sends top-quality audio and performance from compatible devices to deliver dynamic, CD-like sound without any cables. With a wireless connection range of up to 35 ft. (11 m), you can conveniently control the connected audio without having to return to your Bluetooth® device for control. This means your device can stay safely tucked-away from the elements.

  • Thanks to the MBT-CRX Bluetooth® Audio Controller / Receiver, taking your playlist with you has never been easier or sounded better.


  • Bluetooth® Wireless Technology
    • Summary: Secure and convenient wireless connectivity across a wide range of electronic device platforms.
    • Detailed Information:
      • Inspired by the Danish King, Harald Bluetooth, who unified Denmark and Norway in the 10th century, Bluetooth® wireless technology is used throughout the world today, enabling billions of electronic devices to connect wirelessly. With its uniform specification structure, low power consumption and ease of use, a wide range of Bluetooth® equipped devices are securely connected to each other (a process known as "pairing"), affording them seamless communication and data transfer.
      • Bluetooth® is the global standard for wirelessly connecting electronic devices.
  • aptX® Audio Coding Technology
    • Summary: Bluetooth® streaming audio can now get closer than ever before to CD-quality sound, when using an aptX® enabled streaming device.
    • Detailed Information:
      • Originally developed in the 1980's at Queen's University Belfast, the aptX® coding algorithm has been the secret weapon of the professional audio and film industries because of its ability to deliver CD-like quality audio over low-power Bluetooth® wireless connections.
      • When sound waves are transmitted over Bluetooth® as digital audio, they are first compressed to reduce their size using a coding method called "SBC", which stands for Low Complexity Sub Band Coding. the compression process takes a series of snapshots of the audio at specific moments in time known as "samples" and, with enough samples, a Bluetooth® receiver can convert them back into a full sound wave.
      • Since Bluetooth® is limited by a maximum available bandwidth and because SBC was designed to use as little processing power as possible, some of the data is discarded using a process called "psychoacoustic modeling". Psychoacoustic modeling removes portions of data that theoretically cannot be heard to reduce file size. The result is less than accurate audio reproduction.
      • To overcome the low-power constraints of SBC and the bandwidth limits of Bluetooth® audio, the patented aptX® coding algorithm applies a different approach at bit rate reduction. By using a method of "time domain ADPCM" to encode the audio, aptX® uses fewer bits per sample, so the files are smaller and arrive transparently and intact. The result is full bandwidth audio reproduction that requires less energy and size for transmitting.
