Audison B-CON - HI-RES Bluetooth Receiver

The Audison B-Con is the first and only Bluetooth 5.0 player in the automotive sector to receive the "Hi-Res Audio Wireless" certification from the Japan Audio Society.

Audiophile performance over Bluetooth is all about the codec - the digital encoding format that both the sending and receiving devices use to transmit the data. Part of the "pairing" process is for the two devices to agree on which codec they will use. We can only choose a codec that both devices - the sender and the receiver - both support.

All Bluetooth devices support a codec called SBC. It is the base codec in the Bluetooth specification. It's not a lossless codec. It's decent, but it's not great, and it sounds pretty bad under certain conditions. However, the Bluetooth specification allows you to use a better codec than SBC - as long as both devices support it. Some of these other codecs promise "high resolution" support, but in reality the connections made with these codecs are often not made at the highest level of quality - the user may not get what they expect. It's usually impossible to see - it does so invisibly at the Bluetooth wireless level.

B-CON USES A POWERFUL CODEC CALLED LDAC

LDAC is now available in many Android phones as well as many audiophile digital media players. Like most codecs, the LDAC data link can be implemented at different quality levels, but at the highest level it is a lossless codec. Our rigorous lab testing shows that over the highest quality LDAC connection, analog frequency response reaches 40kHz - and this is the mode that has earned the B-CON "High Resolution" certification from the JAS.
