A:Answer Thank you for your interest in our SoundTouch Wireless Link Adapter!
The SoundTouch Wireless Link adapter is designed to make a speaker Wi-Fi and Bluetooth compatible.
The adapter connects to a speaker or amplifier through an optical, AUX, or L/R RCA cable, and acts as an input. You then connect to this adapter through an AUX input, through Bluetooth, or through Wi-Fi on our SoundTouch app.
If you had an adapter connected to all your speakers in your household, you would be able to group these together and play a source from one of the above methods, allowing this to play to all the speakers in the household.
We hope this helps answer your question!
