The Audio-Technica's ATW-R2100 receiver is matched with the ATW-T210 UniPak Microphone System transmitter and AT829cW lavalier microphone for simple-yet-powerful wireless performance. At the touch of a button, the receiver will quickly find an open channel. Interference isn't an issue thanks to the Tone Lock system, and the ground lift switch prevents hum caused by ground loops between the sound system and receiver.
