I was thinking about this and if you set the EQ for the FOH it will be wrong for the monitor. Unless you've already compensated for both speaker sets with the 32 band EQ. Prep work really helps.
Some interesting discussion to date but I think we are drifting off the topic.
Wynn,
I typically do compensate for the FOH and each foldback send using the GEQ. After doing so, I've started to try the aux sends for the foldbacks in both the pre and post EQ/dsp positions. Often the post EQ/dsp positions sounds better than the pre (nicer more natural sound). Don't ask me why this is, as my channel EQ is typically the hpf set at around 110 Hz and fairly flat from there up plus a very gentle compressor setting.
I was eagerly awaiting the last update so I could have pre EQ/dsp aux sends but it seems it was not as critical as I thought. I still like have the option and will always go 'pre' for bands that want really loud foldbacks or if I need heaps of compression to tame a wild vocalist.
I know some folk here always use 'post' for their aux sends to foldbacks and that seems to make a lot of sense if you are not having to deal with feedback prevention.
In the digital world, I guess it wouldn't be all that hard to add additional channel Eq for each of the aux sends - probably overkill but it sure would be useful for nice monitor mixes. Also would be nice to have the option of using parametric or the GEQ on the aux sends. HPF in particular would be nice to have on each aux send.
Cheers
