Audio-Technica ATW-2120a

Comments about Audio-Technica ATW-2120a 2000 Series Handheld Wireless System:

Ordered 5 of these units for my church worship group. Now I'm just a weekend sound guy with no training. Installation was a snap. Set the channel on the receiver and the Mic. put in the batteries hook up the antennas plug into sound board and Done!These units work Great!! My whole team just loves them. The sound is pure and crisp. I have some people who seem to be a little afraid of mics and hold them at a distance. No problem with these beauties. The sound pick up is super. I use to have to keep my gains almost maxed out with my old mics, but with these I have been able to turn them down 40%-50%, also I use less volume which reduces a chance of whooping feed back!!If I need more mics I know what to get!! I definitely recommended these!

Comments about Audio-Technica ATW-2120a 2000 Series Handheld Wireless System:

I sing in an Acappella Quartet and we are looking to upgrade to wireless mics. Before i bought this mic, we had sung at a tent revivals where they supplied the sound. I was handed this mic to sing with. It was awesome. The whole evening I was able to sing confidently without having to worry about a mic cord and the sound that this thing puts out is amazing for the price that you pay. I guess that's Audio Technica for you. :-) Anyway - this mic has done me very well. The ONLY thing i would change is to add a battery meter. But, i understand that when buy a mic for this price, you're not going to get some of those extra features. If you get this mic, i'm sure you won't regret it.
