The Audio-Technica ATW-3211N/831 is a 3000 Series (4th generation) network-enabled rackmount wireless lavalier microphone system with professional-level features for enhanced reliability and control. It offers Ethernet networking for quick multichannel setups and an intuitive interface with a dual-mode OLED display for easy operation. With a wide 60 MHz tuning range and true-diversity reception, the system minimizes potential dropouts to deliver intelligible, natural audio for presenters, clergy, lecturers, and performers working in business and educational settings, houses-of-worship, theaters, or on musical stages.





The ATW-3211N/831 includes a half-rack receiver housed in a rugged, full-metal chassis with removable antennas, well suited for rackmounting in portable flight cases or permanent installations. The receiver's auto-scan function searches 2395 selectable frequencies, seeking out a clean, interference-free channel for your audio transmission. The 3000 Series lets you set a clean backup frequency in advance, which you can quickly switch to with a press on the transmitter's multifunction button in the event of unexpected interference.





This system features an AT831-cH cardioid lavalier mic that provides crisp, full-sounding voice pickup, while also excelling as an instrument mic. The bodypack transmitter is equipped with a rugged metal housing and a proprietary Hirose 4-pin cH-style screw-down connector for secure connection. The transmitter provides up to 9.5 hours of operation on two AA NiMH rechargeable batteries (available separately), with a selectable 10/30mW RF power output for overcoming interference in difficult RF environments. The transmission range is up to 330'.





The Ethernet connection on the receiver allows multiple receivers to be easily networked together for simplified frequency coordination and deployment via Audio-Technica's Wireless Manager Software (WMS). Up to 40 mic channels can operate simultaneously in each frequency band.
