Consumer Alert:

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCCs wireless microphone website at:

Comments about Audio-Technica ATW-2120 Handheld UHF Wireless System:

We use 5 of the Audio Technia 2000 Series Wireless microhones systems at a House of Worship. Since installing them over a year ago we have incountered no problems. Very easy to use even by a Lay Person. Long battery life, no interference, and high quality design. Highly recommended. My background is over 35 years in communications, and audio/video.

Best bang for the buck

By Kevin R.

from East Hanover, NJ

Comments about Audio-Technica ATW-2120 Handheld UHF Wireless System:

I checked Shure, Senn, etc and found this system to be the most competitively priced "pro" unit out there. I use it for live performances in a full rock band and find that it sounds better than my wired Shure 58 and has been just as reliable. I have not had to change channels as I have never had any interference from outside sources. (To be fair, I should mention that no one else in the band is running wireless). If this unit was stolen tomorrow, I would not hesitate to replace it with the same exact model.
