Key Features
  • For Video, Broadcast & Sound Designers
  • Switchable Low-Frequency Roll Off
  • M-S Mode and Left/Right Stereo Modes
  • Suitable for Camera Mounting
The BP4029 (AT835ST) Stereo Shotgun Microphone from Audio-Technica offers two internally-matrixed modes which provide traditional "left-right" stereo. To accommodate varying acoustic environments, the user may select between a "wide" pattern (LR-W) with increased ambient pickup, and a "narrow" pattern (LR-N) which offers more rejection and less ambience.

In M-S mode, the BP4029 provides independent Mid and Side signals. This allows the Mid-Side balance to be adjusted as desired at the recording desk or mixing electronics, reducing the amount of equipment necessary in the field.
