Audio-Technica AT831cW Lavalier Microphone
The AT831cW is the cardioid condenser lavalier from Audio-Technica's AT831 family, terminated with a locking 4-pin HRS-type connector for Audio-Technica UniPak bodypack transmitters. Its cardioid pattern favors the wearer and rejects sound from the sides and rear, controlling feedback and room noise where an omnidirectional lavalier would struggle.
The 55 inch cable routes cleanly to a UniPak beltpack for presenters and performers on the move, and the mic clips discreetly to clothing for speech or to acoustic instruments that need isolation. It ships with an AT8116 windscreen and AT8419 clothing clip.
