Pre&Post AUX!!!

[Reggaesoldier]

So I've got a pre aux and a post aux for each channel on my mixer. 2 Sets of Stereo Aux returns and 2 aux send's, (for ea. pair of returns). I use the first (pre) Aux for my mod pro and the 2nd, (post) for nothing yet! What is the Post aux for? Another FX unit? Am I even using this shit right in the first place? Or is it for something else? I'm not really sure. I just need clarificationon what I use it for or what I could possibly do with it. Thanks

It's pre and post fader...

Say you're in pre-fade, and you put some verb on the drums. If you bring the faders down, you still get the verb. In post-fade (my personal preference 90% of the time) if you bring the faders down (or up) the signal to the verb increases or decreases along with the signal from the faders.

For the most part, unless you're running out of channels, most people tend to run their effects back to channels instead of aux returns - This allows you to buss/group them, EQ them, compress them, mute them, etc.

The only time I really use pre-fade is for cue mixes or monitor mixes live. Well, not the "only" time, but "mostly" to be sure.

Most of us at home are ALWAYS running out of channels

Other than that, obviously John's right. It's interesting that Behringer actually label their pre-auxes 'MON' and their posts 'FX' with pre and post only in little writing underneath. There's a big clue in that!

You lost me... The way I'm currently seeing this is, most people run the FX unit back into a channel? Isn't that what the aux ins are for? And wouldn't running into a channel only cover whatever you had plugged into the unit iteself? If this makes no sense let me know! other than that thanks for your time! and i'm not sure what buss grouping is?

Let's assume that we're using post-fader aux for reverb and you're using the first 10 inputs on a 16-channel mixer...

You send some of the snare, some vocal and the guitar leads to the reverb through the aux. You take the reverb outputs and run them to 15 & 16 so you can either buss them or insert compression or just for fine control over the verb. If othing else, it's easier and more accurate to mute the channels when you want to mute the verb than trying to bring a knob back to the exact position it was in before.

Make sense?

Yeah, he's saying bring the 'returns' back in to a new channel, not the one you sent from to start with. It gives you many more options but it depends whether you need them or not!
