what is a mult

I think I've got a pretty good idea already, but could someone explain the process of "multing up " a signal, give an example of uses and common ways this is accomplished And how this would be, could be applied within the Pro Tools enviorment?
I don't recall seeing this done before, I assume that a patch bay is involved (when analog) but would really appreciate a walk through or suggestion of where to read up on it. Thanks for any help.

A mult is a splitter. You plug the signal into one point, and it comes out of 2 or more points on the patchbay, which you can then route to 2 or more different pieces of gear. In other words, it enables you to send the same signal to "mult"-iple inputs.

For instance, say you want your snr to have a quick pop on the lows & mids but natural decay on top (maybe the room had a nasty resonance you want to get rid of without ruining the rest of the natural ambience)... you can run the snr track directly from the multitrack into the mult, then from the mult into 2 adjacent channels on the mixer. From there, EQ each channel so the 2 desired frequency ranges are emphasized, and apply the different dynamics to each channel.

There are a lot of different possibilities. They come in very handy. I recommend putting at least one on the patchbay if you're building it now. It's better to have a mult and not need it than to wish you did have one.

As for ProTools... A mult might still come in handy, tho it would depend on how you use PT. Hard to think of a scenario for that. Maybe if you have more physical inputs than outputs?

Within ProTools you would realize a "mult" by either routing an Aux-Send within your source channel to a bus and then take the bus into several channels. Or - in a tracking situation - you could (I think so) assign the same physical input to several different channels at the same time.
Either way, what you then do in those channels is up to you...

Thhe only problem with multing on Pro Tools is the delay between the tracks(on analog this isn't as big of a deal). What you would have to do is record the tracks and shift them till they are in sync with your originals. Sometimes this works well, sometimes it doesn't. This is one of the biggest turn offs of digital mixing.

Any patchbay that can be configured as "half-normalled" can be used for a two-way mult. By patching from the top row jack (output) of one channel on your patchbay to any another input (bottom row, but not the one directly underneath) you now have multed the signal. Both the patch cord destination as well as the "normalled" jack that is directly underneath the original output are receiving the same signal...

Hmmm - I'm not sure my explaination is very clear. It's not very hard, but for some reason I'm not describing it too well! Someone else want to try?
