I've not necessarily thought about doing this before and have something coming up that would be stepping up my game to a degree. It's probably kind of a newbie question at least in regard to doing this...
The scenario is one where I'd like to get the instrument mics/direct feeds before processing in the board. I don't at this point know what the capabilities of the board are but it will be a small one (and most of what I see at shows I go to are small, old, not very good boards - not digital, not with any built-in multitrack recording path). 4 to 8 channels is probably the most I'd find where I'd need to take this approach.
What would be the best/simplest solution, preferably relatively inexpensive (with specifics if any have recommendations)?
I won't be doing this a lot but will have opportunities from time to time. I don't want to invest in a board or huge pile of equipment to do it.
