Audio-Technica ATW-2120CI System

The ATW-2120CI is a handheld system from Audio-Technica's 2000 Series, a frequency-agile UHF platform aimed at presenters, houses of worship, and small venues that want dependable wireless without a coordination headache. It pairs the ATW-R2100 receiver with the ATW-T220, a cardioid dynamic microphone and transmitter built into one handheld body.

The receiver runs True Diversity, choosing the stronger of its two antenna sections to reduce dropouts, and automatic frequency scanning finds a clear channel from ten user-switchable options. Audio-Technica's Tone Lock tone squelch ignores stray RF so the system stays quiet between words. It operates in frequency band I, 487.125 to 506.500 MHz (TV 16-20).
