- Miniature Capsule
- Cardioid polar pattern
- High sensitivity
- Frequency response of 40Hz to 20kHz
The Audio-Technica AT831B 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 minimising 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.
The miniature, unobtrusive capsule allows for easy concealment underneath clothing.
Cardioid Polar Pattern
The cardioid polar pattern is effective in minimising audio signal at the off-axis sections of the capsule. This provides high gain-before-feedback response while using nearby monitors and speakers.
The frequency and sensitivity response of the AT831 result in transparent, pristine audio signal reproduction with low noise floor.
