Wireless Lav Mic Set - Audio Technica U100 Series Full UHF Diversity, 100 Selectable Channels Transmitter: ATW-T101x with plug-in lavalier mic, 1 x 9V power. Receiver: ATW-R100x, XLR and 1/8" headphone out, BNC antenna connections, 2 x 9V or external power. Includes transmitter, receiver, mic, antennas, and nylon mounting sleeve for receiver. Purchased in '04, but probably has less than 25 hours of actual use. Works beautifully. It's mostly just been carried from shoot-to-shoot, so we apparently don't need it. Photo below is the actual set. Location: Boise it's NOT ok to contact this poster with services or other commercial interests idaho
