This little box is magic! We enjoy the sound of its mobile devices on good speakers via Bluetooth easily and with quality sound. The name given by Logitech is not precise: It has no built-in amplifier, connect the audio output jack (or 2xRCA) an amplifier and speaker, or powered speakers. Supplied with a power supply and a Jack-RCA cable * 2 basic, the implementation is very simple: Connect the device to the mains and an amp, press the button to turn bluetooth pairing mode and the association from the transmitter (mobile, tablet, ...) and it's over. As said many times here, the output volume is very low, so you have to push the volume of the amp. By cons, no bed and no perceptible breath, and the sound is really quality for wireless. . Lets enjoy the joys of dematerialized music at home: - My Disco MP3 Music on Google - The Google Music player on a Nexus 7 tablet => MP3 streaming are read, no need to store on the tablet. - The Bluetooth receiver in this room - A Class-T amp SA-50-50 - A good pair of speakers behind => And here is a chain of very good quality, small size (except pregnant), inexpensive, very far 20,000 titles online! And you can vary the sources: From MP3 streaming via legal platforms, online radio, etc ... since mobiles, tablets and PCs have access to a large number of sources.
