I would have to agree with douglas t allen. Even though every setup is different, the main problem frequencies per channel stay about the same.
I used to dial in those frquencies, only not as much as would be sometimes required. So instead of -8 dB i would cut 4 dB and listen what happens, and adjust accordingly.
This was mostly at festivals, with no soundcheck, only linecheck.
Edit:
Since i went digital i have a different default setting per venue. Some venues i visit every week.Gates and compressors are all set, but are set at levels so they don't do anything. Lowcut on vocals etc. Monitor sends down, monitor eq set, fx sends at drums and vocals set. Main eq also set. Still i find myself adjusting the main eq. Depends on type of music, and mainly how many visitors. The other big factor is the foh engineer. They are usually human. Everyone has their own style of mixing, so all you can do is giving them a setting which is workable, but will never be perfect. Next time, same engineer will do things different.
I wouldn't worry about which desk is used, as long as it is the right tool for the job. As i said: other factors play a lot bigger role.
