The Audio-Technica ATW-3211 is a 3000 Series (4th generation) rackmount wireless 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-3211 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 a bodypack transmitter equipped with a rugged metal housing and a proprietary Hirose 4-pin cH-style screw-down connector for secure connection with a compatible lavalier or headset microphone of your choice or an instrument cable. 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'. Up to 40 mic channels can operate simultaneously in each frequency band.
