Description

The AT831R is a miniature clip-on/lavalier condenser microphone with a cardioid polar pattern. It is designed for quality sound reinforcement, professional recording, television and other demanding sound pickup applications.

The microphone is intended to be worn on the clothing or used as an instrument mic for excellent yet unobtrusive sound pickup. The wide-range capability of the microphone ensures clean, accurate reproduction with high intelligibility for speakers and presenters as well as for instrument pickup. Its small size makes it ideal for use in applications where minimum visibility is required.

The microphone requires 11V to 52V phantom power for operation. The microphone’s cardioid polar pattern provides a 120° angle of acceptance. The microphone includes a (13.1") permanently attached miniature unterminated cable. A recessed switch in the power module permits choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass UniSteep® filter) to help control undesired ambient noise.

The microphone comes equipped with a power module, a clothing clip, an instrument adapter, a windscreen and a protective carrying case.

Features

  • Clip-on lavalier mic provides crisp, full-sounding voice pickup
  • Also excels as an instrument mic, especially for pickup of acoustic guitar with included AT8444 instrument adapter
  • Excellent gain before feedback and suppression of background noise
  • Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source
  • Rugged design and construction for reliable performance
  • UniSteep® filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
