The Audio-Technica ATW-T220C is a specialized handheld transmitter designed for use with 2000 Series wireless systems. This unit combines a cardioid dynamic microphone capsule with a wireless transmitter to deliver reliable audio performance in live sound environments.
The ATW-T220C utilizes a dynamic element featuring a cardioid polar pattern. This directional pickup focuses on the sound source directly in front of the microphone while reducing the pickup of sounds from the sides and rear. This design improves isolation and helps minimize feedback during vocal performances or presentations.
This transmitter integrates seamlessly with Audio-Technica 2000 Series components to maintain signal integrity throughout the wireless chain. The package includes the AT8456a QuietFlex stand clamp, which allows for secure mounting and flexible adjustment on standard microphone stands.
