Bring discreet, hands-free wireless operation to professional presentations and performances with the Audio-Technica ATW-DT3201 body-pack transmitter for the D50 digital UHF wireless system and included AT831cH lavalier microphone. The compact transmitter features a secure cH-style screw-down 4-pin connection, external controls and an OLED display for straightforward operation, while SideTrack functionality allows audio to be switched to a second output for discreet communication with performers or audio engineers. The included AT831cH cardioid condenser lavalier delivers crisp, full-sounding voice pickup across a 40Hz–16kHz frequency response, with strong gain before feedback and suppression of unwanted background sound. A custom rechargeable lithium-ion battery supports extended professional use and can be charged in the transmitter with the optional ATW-CHG6 station or removed for charging with a compatible ATW-CHGA6 charger, while the included windscreen and clothing clip complete a versatile setup for corporate AV, houses of worship, theater and live production.
