SID Audio In

I am making a MIDIBox SID with full controler option. The hook up diagram says to ground unused audio in terminals and shows none of them in use. Can I hook up and use all my audio in’s as well as the audio out’s?

Thanks

I believe so, yes. Just if you are not using them, ground them. If you do use them you may want to use a switch type jack (normalled) that shorts to ground when no cable is plugged in.
