It is an an extremely flexible, professional, and easy-to-use portable wireless system..

ATW-R1810 single-channel receiver
The Audio Technica ATW-R1810 single-channel receiver has true diversity operation: two antennas feed two completely independent RF sections on the same frequency; automatic logic circuitry selects the superior signal. The ATW-R1810 features BNC-type antennae connectors, output and monitor levels, a balanced XLR output and a LCD (Liquid Crystal Display) that shows battery status and frequency settings.

ATW-T1802 plug-on transmitter
The ATW-T1802 plug-on transmitter features a locking XLR connector for adapting dynamic and condenser microphones and selectable high and low transmission modes to conserve battery life/maximize power. The ATW-T1802 Plug-on Transmitter also provides power to condenser microphones rated to operate on 12V phantom power or less.
