The Audio-Technica AT831C is a miniature cardioid lavalier microphone with a sensitivity and frequency response suitable for professional video, broadcast and sound reinforcement applications. The cardioid polar pattern is effective minimizing off-axis signal, providing high gain-before-feedback while using nearby monitors and speakers.
The wide frequency response of 40Hz to 20kHz enables audio signal to be reproduced with accurate detail and minimal noise at low frequencies. The miniature capsule enables the microphone to be hidden underneath clothing and the included windscreen protects against noise caused by plosive signals and wind.Unterminated Cable The AT831C version of the AT831 features an unterminated cable. User's are capable of wiring custom connectors as necessary (refer to wiring diagram in manual). Miniature Capsule The miniature, unobtrusive capsule allows for easy concealment underneath clothing. Cardioid Polar Pattern The cardioid polar pattern is effective in minimizing audio signal at the off-axis sections of the capsule. This provides high gain-before-feedback response while using nearby monitors and speakers. High Sensitivity The frequency and sensitivity response of the AT831 result in transparent, pristine audio signal reproduction with low noise floor.
