Audio connections Main Inputs and Outputs The Alligator is normally connected as a stereo in-stereo out effect. Should you connect a mono input signal, the output will still be in stereo due to the pan controls. Separate Outputs These output the signals from the individual gate/filter channels. Connecting one of these outputs will remove the corresponding channel signal from the main output. The separate output signals are taken after the Channel Volume controls but are unaffected by the Master Volume.
