JL Audio Marine Weatherproof Bluetooth Controller MBTCRX Designed for marine and powersports applications, the MBT-CRX Bluetooth® Controller/Receiver delivers your favorite music from a Bluetooth® equipped device directly to your audio system.

With an IPX6 water resistance rating, the MBT-CRX is ideal for small watercraft, motorcycles, ATV’s or other utility vehicles. Add Bluetooth® connectivity to any source unit with line-level/auxiliary inputs or connect directly to an amplifier and use it as a stand-alone source unit/receiver. Large LED backlit push-button controls are easy-to-see and easy-to-use, day or night. A small footprint and clever, one-hole design makes installation a breeze. An adaptor plate is also included for easy front mounting or where rear access is limited or not possible.

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

When you’re ready to set sail or tackle your next adventure, great sound is waiting for you with the MBT-CRX Bluetooth® Audio Controller/Receiver.

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 munication and data transfer.

Back to top aptX® Audio Coding Technology 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 pressed to reduce their size using a coding method called "SBC", which stands for Low Complexity Sub Band Coding. pression 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 e 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.
