Can I connect two of these speakers together?
You can only select one unit as a Bluetooth output source. However, you can “chain link” additional speakers by using a 3.5mm audio cable. Simply connect one end of the audio cable to the “line-out” port of the active Bluetooth/playing speaker and the other end to the “line-in” port of the speaker that you want to add on.
NOTE: The output signal is mono.
