Audio Technica ATW-2120B (U) 2000 Series Handheld system with 220q Mic CH38

Audio Technica ATW-2120B 2000 Series Handheld transmitter system ATW-R2100b receiver ATW-T220a handheld cardioid dynamic microphone/transmitter Automatic frequency scanning Up to 10 user selectable channels available Tone Lock䋢 squelch function fights interference

The ATW-R2100b receiver features true diversity reception. Two antennas feed two completely independent RF sections on the same frequency; automatic logic circuitry continuously compares and selects the superior received signal, providing better sound quality and reducing the possibility of interference and dropouts. The receiver also offers a switchable output attenuator to reduce the level of the output signal by 12 dB for flexible use with a variety of system configurations.

The versatile ATW-T210a UniPak® body-pack transmitter has both low- and high-impedance inputs plus a bias connection, for use with dynamic and electret condenser microphones, as well as Hi-Z instrument pickups. The UniPak® transmitter also offers separate trim controls for instrument and microphone, plus switchable high/low RF power. 

The ATW-T220a handheld dynamic microphone/transmitter features the same element used in the PRO 41 dynamic handheld microphone created for professional live-sound venues. It also offers switchable high/low RF power. Both the ATW-T210a UniPak® and ATW-T220a handheld transmitters also offer charging contacts so the units can be placed in an optional recharging station for multi-transmitter charging.
