Product Overview
The Audio-Technica AT831cW is a miniature cardioid condenser lavalier microphone terminated with a locking 4-pin HRS-type connector for Audio-Technica UniPak body-pack transmitters. Its cardioid pattern rejects off-axis sound to improve gain-before-feedback for presenters and lecturers in commercial AV rooms.
Product Description
The AT831cW clips to a lapel and delivers clear, directional speech on Audio-Technica cW-style UniPak wireless systems.

Frequency response runs 40–18,000 Hz with a 200 ohm impedance and an integral 80 Hz high-pass filter. A 55″ cable terminates in the locking 4-pin HRS connector.
For a cH-style version for other Audio-Technica body-packs, see the AT831cH.
