MM - I am not sure we are on the same page. This soundboard gig is an occasional deal, not my reason for living. I do mostly remotes and almost always on battery power to avoid any chance of AC interference. This sound board gig just showed up on Thursday. C-link has, so far, been fine. With the 788T I can run off its word clock, I believe. I have not checked that, but am confident of the C-link.
The sound board on Saturday only had 8 channels working. How many mics should there be on a guitar amp? Just because there are 32 channels does not mean they will all be used all the time. And, like my 12 channel capability, they are there should they be needed. I do not think I will be doing a lot of 12 channel work. But, a trio in town will require three spots, one for each guitar and one for the bass, a MS - AB setup I am working with, and a vocal mic to be eight channels. If it gets freaky I can pack a 722 or two along. This Sunday gig is a constant but was a trio tonight as the drummer was not there, thankfully. He is a R&R drummer playing in a jazz group. He has one level: too loud.
There is more than one solution to these problems. I keep experimenting as there is no on I can tag along with to learn from. The one guy is the fellow who is teaching me the sound board. He has setup venues, tuned them and run sound boards for about ten years and about the same amount of time touring in R&R bands and running his own saloons. I am not super keen on the R&R end but it is something to learn and I am sure it will come in handy along the way. I am getting paid to learn. It is just like I am back on the GI Bill again.

Cheers
