The PROBOKS allows you to connect several SOUNDBOKS, instruments or equipment.
With the PROBOKS you have several different out-puts (read about the out-puts here), when connecting the PROBOKS to the SOUNDBOKS with AUX-cords. You can choose to play in stereo, in mono or assign left and right speakers. You can connect up to 6 SOUNDBOKS to your mobile device or computer, through the PROBOKS via an AUX-cord. The PROBOKS is battery-powered and rechargeable, therefore you will have a fully mobile set-up when connecting with several SOUNDBOKS etc.
