Audio-Technica AT831CH Cardioid Condenser Lavalier Microphone
Product Overview
The Audio-Technica AT831cH is a miniature cardioid condenser lavalier microphone terminated with a cH-style screw-down 4-pin connector for Audio-Technica body-pack wireless transmitters. Its cardioid pattern rejects off-axis sound to improve gain-before-feedback for presenters and lecturers in conference rooms and houses of worship.
Product Description
The AT831cH clips to a lapel and delivers clear, directional speech pickup on Audio-Technica cH-style wireless systems such as the 3000 Series.
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 screw-down 4-pin cH connector.
This is the lavalier included in the ATW-3211/831 wireless system.
Key Features
- Cardioid lavalier capsule — A directional pattern rejects off-axis sound to improve gain-before-feedback for presenters.
- cH-style termination — A screw-down 4-pin cH connector mates with Audio-Technica body-pack transmitters.
- Integral 80 Hz high-pass filter — An integral filter controls rumble and handling noise for clean speech.
- Discreet clip-on form — The miniature lavalier mounts unobtrusively on a lapel for presentations and broadcast.
- 55″ cable — The cable reaches a body-pack transmitter worn at the waist.
