I'd advise that you keep in mind that you are there to record the comedian, not the crowd... What I mean is, set your levels to the volume of the comedian's voice; I suspect that the laughter and applause will be WAY louder than the performance, in my opinion I would rather have way clipped laughter which I'll envelope down in post-production than a way too quite comedian (who should be the focus of the recording) who's quality may well become distorted when amplified later.
That' just may two cents.
And, of course, the above reply is super logical aswell-- as the closer the better.
