Audio-Technica AT831CT4 Miniature Lavalier Microphone
Product Overview
The Audio-Technica AT831cT4 is a miniature cardioid condenser lavalier microphone terminated with a TA4F (cT4-style) connector for compatible body-pack wireless transmitters. Its cardioid pattern rejects off-axis sound to improve gain-before-feedback for presenters and lecturers in commercial AV rooms.
Product Description
The AT831cT4 clips to a lapel and delivers clear, directional speech pickup on a wireless body-pack system that uses a TA4F input.
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 TA4F (cT4) connector.
For a wired version with a phantom power module, see the AT831b.
