Okay. I'm not sure how to find samples of different gear at archive.org. All my searches are coming up empty. What am I doing wrong?
Also, here are the specs I've found on the three mic sets I'm looking at. I'm doing my best to understand what's what, but I'd love to hear your two cents on how they stack up:
-Church Audio - there are three things available:
