Audio-Technica ATW-3211/831 3000 Series Fourth Generation is a frequency-agile, true diversity UHF wireless microphone system designed to give users the power and flexibility to operate within the congested UHF spectrum. The system includes an ATW-R3210 receiver, an ATW-T3201 bodypack transmitter and an AT831cH cardioid condenser lavalier microphone, and is designed to capture voice and instruments with intelligible and natural sound while minimizing potential interference, for stage, television, lecture, event presentation, or house of worship applications. 

Available in two frequency ranges 470 - 530 or 530 - 590 MHz, offering a 60 MHz tuning range, which is more than twice that offered by the previous versions. Frequencies can be easily scanned and selected on the receiver, and then synced with the transmitter via IR sync functionality. In case of interference, the Multifunction button on the transmitter lets you quickly switch to a backup frequency so you can keep working with minimal interruption.

The ATW-R3210 receiver is equipped with two flexible antennas, a balanced XLR output, and an unbalanced 1/4" output. The ATW-T3201 bodypack transmitter is powered via two AA batteries and features a rugged metal housing with a cH-style screw-down 4-pin connector for secure connection to the microphone. The AT831cH microphone allows for close miking of voice and instruments (especially acoustic guitar) with crisp and clean sound. Its cardioid polar pattern effectively rejects unwanted background sound and helps reduce feedback on stage.
