you want this big boy?
could anyone tell me how to wire up a mult in my patchbay? thanks for any help.
 
Some patchbays allow you to create multis by soldering wires between the cards. Your manual would have that info.

However, if that is not possible, what you would typically do is on the rear of the patchbay wire the bottom rear of the original incoming signal card to the top rear of whatever card you want the mult to come out of.

So if the patchbay is 1/2 normalled and you want to mult input 1 to input 2, you'd take the lower rear jack of the card 1 and patch it to the upper rear of card 2.

This is of course assuming that you use the upper rear input jack for the incoming signal! You would then use the upper front jacks of a1 and 2 in this example for the original signal and the multed signal. As long as you don't break the connection by jacking into the lower front input of card 1 you will be fine.

Hope all this makes sense.
 
what are these cards you're talking about? I have a basic 1/4" patchbay, instead of the standard hardwired elco-pin patchbays used in most large studios.

so let me see if this would work...if I wired the bottom jack of a half-normalled row to the top jack of the row right next to it, then wired the bottom jack of that row to the top jack of the one next to it...and so on and so forth.

would that work? thanks for the feedback.
 
If you have the typical 1/4" patchbay, it will be a metal frame housing a bunch of little circuit boards with the jacks on them. Those are the cards I'm talking about.

The way I would do it is take 8 inputs (1-8) and then mult those to 8 more inputs (9-16). If you want to mult one input you'll use up two slots on your patchbay. Mult four inputs and use up eight inputs.

If you mult the way you describe, you'll end up multing the same signal over and over. If you want to mult a signal, just double it basically, then you need to think of the patchbay slots (cards) in pairs. So the lower rear of card one goes to the upper rear of card two. That is one mult. Then the lower rear of card three goes to the upper rear of card four. That's you second mult.

Hope this makes sense. Easy to show in person, difficult to describe in words.
