Audio-Technica 3000 ATW-3211/831 Wireless Microphone System

The ATW-3211/831DE2 is a fourth-generation 3000 Series wireless system built for crowded RF environments. Its 60 MHz tuning range across Band DE2, 470 to 530 MHz, is more than twice what the previous generation offered, which gives you somewhere to go when local broadcasters and other wireless gear fill the spectrum.

Setup is scan and sync. The ATW-R3210 receiver scans for open frequencies, you select one, and IR sync pushes it to the ATW-T3201 body-pack transmitter. You can also set a backup frequency ahead of time and swap both units to it with one press of the transmitter multifunction button if interference appears mid-show.

The package includes the AT831cH miniature cardioid condenser lavalier microphone, which connects through a rugged cH-style screw-down 4-pin connector that will not shake loose. The body-pack has a metal housing, a tactile mute toggle for physical confirmation when you cannot see the display, and charging terminals for optional ATW-CHG3 and ATW-CHG3N docks.

True Diversity reception reduces dropouts, Auto Squelch adjusts to maximize range against interference, and OLED screens on both units display settings and alerts. A ground-lift switch removes hum from ground loops, antenna power supports in-line RF devices, and balanced and unbalanced outputs connect to any console.
