The Audio-Technica ATW-R1100 Wireless Receiver is a compact unit that delivers quality single-channel wireless sound. Unlike larger rack units, the ATW-R1100 is perfect for tight spaces including conferences rooms and small venues or community spaces. The receiver easily fits on desks or tabletops and offers roughly 100 feet of wireless range when paired with a transmitter of your choosing. The ATW-R1100 sports three levels of diversity reception for interference-free reception (frequency, time, and space), while automatic frequency selection makes setup a breeze.
