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.
