Clear sound quality and rock-solid, dependable performance.

The ATW-R2100 receiver is matched with the ATW-T220 handheld cardioid dynamic microphone/transmitter 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 the hum caused by ground loops between the sound system and receiver.
