Product Description

Audio-Technica’s second-generation 2000 Series is a 10-channel frequency-agile UHF wireless system designed to suit a variety of applications, including MI/live performance, fixed installation, public address, A/V rental houses and places of worship. It offers all the advantages of a high-quality, professional wireless system at an extremely affordable price. New professional features include two available frequency bands and switchable antenna power. Also new to the 2000 Series, the optional ATW-CHG2 two-bay recharging station provides power to recharge NiMH batteries in two ATW-T220a handheld transmitters and/or ATW-T210a UniPak® transmitters in any combination.

Offering 10 selectable channels in one of two UHF frequency ranges and True Diversity UHF wireless technology, the 2000 Series features automatic frequency scanning. At the touch of a button, this function automatically determines and sets the best available frequency. Any of the 2000 Series’ 10 channels may be used together without any frequency coordination problems or group selection issues. The 2000 Series also incorporates Audio-Technica’s Tone Lock™ squelch plus an easy-to-read LCD information display.
