Audio Technica ATW-2120CI Wireless Handheld Microphone System - I Band ATW-2120C

The ATW-2120CI is a UHF handheld wireless system pairing the ATW-R2100c true diversity receiver with the ATW-T220c cardioid dynamic handheld microphone and transmitter. It operates in Band I, 487.125 to 506.500 MHz, with 10 selectable channels.

True diversity reception uses two antennas and picks the stronger signal continuously, which keeps audio steady across a typical 300 ft operating range in rooms where reflections and bodies block line of sight. Image rejection of 60 dB nominal and 20 dBuV RF sensitivity hold the noise floor down.

The cardioid dynamic capsule rejects side and rear pickup, giving usable gain before feedback in front of monitors and house speakers. Switchable RF power lets you run 30 mW for range or 10 mW to conserve battery, stretching two AA alkalines to 9 hours on the low setting.

The receiver mounts in a rack with the included adapters and outputs on balanced XLR at +9 dBV or unbalanced 1/4" at +4 dBV, with a two-position attenuator switch for 0 or -12 dB. Two flexible UHF antennas and an AC adapter are included, along with an AT8456a Quiet-Flex stand clamp for the microphone.
