  • 4Cardioid Polar Pattern
  • 5High Sensitivity

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.

question

Do I need a power module or can I just plug this into a mini-XLR to XLR adapter and power it with phantom?
Asked by: PHIL
This version of it has an unterminated cable. This one (AUAT831B) comes with the power module and then you can take an xlr cable out of the module.
