Description

Audio Technica AT851A Unidirectional Condenser Microphone

The AT851A is a wide-range condenser microphone with a hemi-cardioid (half-space cardioid) polar pattern. It is useful in surface-mounted applications such as high-quality sound reinforcement, professional recording, television, and other demanding sound pickup situations. Its small size makes the AT851A ideal for use in applications where minimum visibility is required.

Features:

  • Designed for surface-mount applications requiring high-quality sound pickup
  • Extended frequency response and uniform cardioid (120°) polar pattern
  • Heavy die-cast case and rubber bottom pad minimize coupling of surface vibration to the microphone
  • Operates on battery or phantom power
  • Low-profile design for minimum visibility
  • Also available as: AT851WA in white, AT851CW in black, less power module; 29.5" (0.75m) cable terminated with locking 4-pin connector for A-T UniPak® wireless systems
