Audio-Technica ATW-2129aD UHF Wireless Lavalier System
Audio-Technica ATW-2129aD UHF Wireless Lavalier System is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from One of my best investmentsI bought 4 of these in 2005 (earlier fequency set) and one since. I put a countryman mic onto one and it was used for song leading at our church. We've changed churches and now it gets used in a prison ministry. All 5 are used but only the one has this many hours.Bottom line... after over 1000 hours of use and one repair of the mic wire, this unit still performs flawlessly.Is that how all Audio Technica stuff works?... All mine does.

Audio-Technica ATW-2129aD UHF Wireless Lavalier System

I am looking for wireless microphones for a funeral home project. Will the audio technica units work from around 200 feet away and thru 2 walls? I am concerned that the mic pack will drop out of range if I don't buy the correct system for the job.

Asked by: accurate
Most VHF or UHF systems will have a range of about 300 feet line of sight, so 200 feet through walls may be outer limits of most systems. You may want to contact Audio Technica directly for more details about which system may be the best choice for you.
