Attached to the footplate is a switch that provides the user two operating modes (volume or pan). Use the Stereo Volume/Pan PedalA input / A output for the left channel and the B input / B output for the right channel for stereo signals. For use with stereo cable installations using TRS type stereo plugs, use the B input and B output. For use as a mono volume pedal, use the A input and A output.
