Audio-Technica AT831C Miniature Cardioid Lavalier Microphone
Product Overview
The Audio-Technica AT831c is a miniature cardioid condenser lavalier microphone supplied unterminated, letting an integrator wire it to the connector their system requires. Its cardioid pattern rejects off-axis sound to improve gain-before-feedback for presenters in commercial AV rooms.
Product Description
The AT831c gives integrators a bare-lead lavalier to terminate for a specific transmitter or power module, which is useful for custom installs and standardized wiring.
Frequency response runs 40–18,000 Hz with a 200 ohm impedance and an integral 80 Hz high-pass filter. The cable is supplied unterminated for custom connection.
For factory-terminated versions, see the cH-style AT831cH or the wired AT831b with power module.
Key Features
- Cardioid lavalier capsule — A directional pattern rejects off-axis sound to improve gain-before-feedback for presenters.
- Unterminated for custom wiring — Bare leads let an integrator fit the connector their transmitter or module requires.
- 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.
- Install-friendly — Suited to custom installs and facilities standardizing on a specific connector.
