Okie .. either I'm not getting yer question right or the link button ain't exactly what u r looking 4!?

The link is mainly when u want 2 compress a stereo signal so u want the setting from input 1 (i.e. Left) on the comp. 2 be the same as the setting in input 2 (i.e. right )...

if u want 2 compress 2 different sounds on 2 totally different ways u need one Y cable from the insert on one of the channels 2 one of the input/ output on the comp, and another Y cable 4 the other channel and the other Input/ output of the comp!
