A peer uses a $45 Behringer mixer from B&H and he says it’s been great.
Thanks for all of your thoughts, very helpful! I will sort through all of the suggestions and see what I can come up with.
One follow up question – I don’t think I’m going to be able to go wireless, so I was thinking of just leaving my DVX100 stationary, hooked up either directly to the bar’s system or to a mixer, and then using my other camera to capture footage? Am I missing any red flags in that scenario?
