Bat, was that really necessary?

i believe so, yes.
LOL
there are certain things that are worth discovering on your own, i believe, if you are concerned with truly learning a craft, this being one of them.
the sonar manual by itself, covers almost all of these types of things...
add to that, any manual with any interface that there is, will walk you through the steps.
despite the obvious analog out into 'some' interface, the question also begs to be asked 'how do i route my signals within sonar?', and 'how do i trim my input signals', and about a thousand other questions....
i usually just take the prong thing, and plug it into the hole thing.
heheh
