I'm looking for an affordable, quality lavalier (lapel, not boom mic) system for the small private Middle School where I work. Price is a bit of an issue, so I'm trying to find something in about the $300.00 (or less) range per kit (mic, transmitter, receiver). Going to need to purchase 10 to 12, so don't want to break the bank. Right now, I've been looking at Audio Technica and Electro Voice. Also looking for a decent 16 channel analog board to run them. Most of the boards I have a Mackies, and a 16 channel runs about 700 bucks. Any suggestions on these two questions? Thanks so much!
