Product Overview

The Audio-Technica ATW-2120b is a wireless handheld microphone system that is part of their 2000 Series of True Diversity UHF Wireless Systems. It operates in the "I" frequency band, 487.125 - 506.500mHz, and consists of the ATW-R2100b diversity receiver matched with the ATW-T220a cardioid handheld microphone/transmitter.

The 2000 Series UHF Wireless Systems are designed to suit a variety of applications. This series offers all the advantages of a high-quality, professional wireless system at an extremely affordable price. It features switchable antenna power with 10 selectable channels and True Diversity UHF wireless technology with automatic frequency scanning. At the touch of a button, the automatic frequency scanning function automatically determines and sets the best available operation frequency. Any of the 10 channels may be used together without any frequency coordination or group selection issues. The series also incorporates Audio-Technica's Tone Lock™ squelch, along with an easy-to-read LCD information display. The optional ATW-CHG2 two-bay recharging station provides power to recharge NiMH batteries in two ATW-T220a handheld transmitters and/or ATW-T210a body-pack transmitters in any combination (all sold separately).
