Full Disclosure - I was given this product for testing and review. First of all, I'm a AV systems designer, installer and company owner. I saw the new system two years ago at Denver AVX and expressed my doubts about it's capabilities to the company rep. Turns out he was the VP of Engineering for AT! He sent me a test unit and I sent him back some real world test data. First of all, I was sure that this would have problems and so I set it up to fail. For my first test, I did not remotely mount the RX units. Also I parked it in a sound booth with an active consumer grade WiFi router/access point. I ran two channels for the entire service multiple times, at a range of 60-80 ft. with a clear line of sight and the RF was rock solid. No dropouts, no problems. I was, quite frankly, amazed. I've lived with this unit now for two years, used it for outdoor events, vacation Bible school at my church, two Christmas productions for drama and backup mics and it has never had an issue. I only have a couple minor complaints. The handheld mic does have some handling noise, so that could be improved and once when I blew a circuit breaker at an outdoor event (hey, it happens) I had to re-sync the handheld to the transmitter before the system would work again. I definitely recommend using rechargeable AA's since they use batteries faster than analog systems. However, this is to be expected considering the amount of active RF management built into these units and the fact that they are constantly encoding and sending dual streams of digital audio. In my book, this system is an excellent alternative for the TV bands! Recommended.
