Audio-Technica ATW-3211/831EE1 3000 Series Wireless Lavalier System (AT831cH, EE1 Band)

The ATW-3211/831EE1 is a 3000 Series (fourth generation) frequency-agile true-diversity UHF wireless lavalier system. It combines the ATW-R3210 receiver, the ATW-T3201 UniPak body-pack transmitter, and the AT831cH cardioid condenser lavalier microphone into a ready-to-run package for speech and presentation.

The EE1 band covers 530.000 to 589.975 MHz, and the receiver's 60 MHz tuning range spans 2395 selectable frequencies with an auto-scan function that locates a clean, interference-free channel. True Diversity reception minimizes dropouts, and the cardioid AT831cH lavalier favors the wearer's voice while helping hold back room noise and feedback.
