This Bluetooth 4.2 module is equipped with aptX technology that allows it to receive audio streams with an almost insignificant loss rate. This encoding/decoding technology is intelligent, meaning that data compression automatically adapts to the type of audio file being played, minimizing loss to an almost imperceptible level on FLAC. Conversely, the module will detect by itself when an audio file is already compressed so as not to apply additional compression to it. MP3 files < 350kb/s will therefore be transmitted as is without any processing in order to preserve their definition.

This feature makes this audio module a versatile solution that can be adapted for home use to add wireless connectivity to a fixed audio installation. With its small size, it will also fit into smaller environments such as a car audio system so that all passengers can share their music from their smartphones or tablets. The CSR64215 chip natively has a decoding function. The digital-to-analog conversion is therefore carried out directly upon receipt of the signal. It is therefore not necessary to add a DAC module, which saves a lot of space.

Easy integration into your audio system

This Bluetooth module CSRA64215 has one analog input and one analog output. It can therefore be installed directly between the RCA plugs and the analog inputs of an amplifier. The change of analog / bluetooth source is done automatically according to the pairing status. (If a mobile phone is paired, the analog input will automatically be transferred) and vice versa.

On the wireless side, the CSR64215 chip provides Bluetooth 4.2 connectivity, which provides sufficient throughput for audiophile quality. This Bluetooth chip is mainly natively designed to operate at high audio speeds. This makes it an ideal solution for ambitious audio installations.
