The GT6 was designed to help live musicians easliy switch between mutiple wireless outputs. For example: If there are six different guitars each with seperate wireless transmitters, all six wireless outputs can be connected to the input of the GT6 and when the guitar is changed its just a push of the button to get that wireless output into the system. There are also four seperate outputs that can be selected individually or together. These can route the input signal to seperate amplfiers, effects or to the mixer directly. All inputs are on combo jacks so mono 1/4\", stereo 1/4\" or XLR's can be connected. All outputs are on balanced 1/4\" jacks with output 3 and 4 also on XLR connectors
