This is a very simple product, there is nothing to configure, nothing to turn, you just have to plug it into a power source and is operational.
It is then recognized by the computer or your phone as an audio device and the association is done very quickly. You are now in the same configuration with a bluetooth headset for your phone.
The connection will leave you the choice to connect the transmitter or using a stereo cable with a 3.5 jack socket (supplied) or, and this is where this module is very interesting, it has 2 audio outputs digital or SPDIF (also provided an RCA connector type) or optical (not supplied).
The quality analog stereo output has not been tested, I connected directly to a digital living room Onkyo amp. The transmission quality seemed very good, though I'm not audiophile but I do not think this type of object should be part of an audiophile system.
I used it to listen to music from my phone without any problems, though (but this is due to the bluetooth itself) the maximum distance between your device and this receiver should not exceed 3 meters (it depends if you have furniture or walls between the two). Personally beyond this still worked but was chopped retransmission, there were lots of small cuts.
Finally it is a very good product that relieves us of cable to play sound from a computer, tablet or phone to a hi-fi equipment without loss of quality and maintaining freedom of movement.
