Audio Technica ATW-3211/831EE1 3000 Series Wireless Lavalier Microphone System

The ATW-3211/831EE1 is the Band EE1 configuration of the fourth-generation 3000 Series, tuning across 530 to 590 MHz. That 60 MHz window is more than twice the range of the previous generation, giving you options when the lower UHF bands are already occupied by broadcasters or other wireless systems in your venue.

The ATW-R3210 receiver scans for clear frequencies and IR sync transfers the selection to the ATW-T3201 body-pack transmitter. Set a backup frequency in advance and one press of the transmitter multifunction button moves both units to it if interference shows up during a performance.

The system ships with the AT831cH miniature cardioid condenser lavalier microphone. Its cH-style screw-down 4-pin connector locks to the body-pack, and the transmitter adds a metal housing, a tactile mute toggle you can confirm by feel, and charging terminals for optional ATW-CHG3 and ATW-CHG3N docks.

True Diversity reception reduces dropouts and Auto Squelch adjusts automatically to hold range while minimizing interference. A dual-mode receiver display switches between standard and performance views, OLED screens on both units show settings and alerts, a ground-lift switch removes ground loop hum, and antenna power supports in-line RF devices.
