Audio Technica BP4029 Stereo Shotgun
Based on models developed for the Sydney Games broadcast, the BP4027 (14.96") and BP4029 (9.29") are engineered for high-end broadcast and production use. Users can select a left-right stereo output (wide or narrow) via an internal matrixing system or discreet mid-side signals for later manipulation.
Features:
- Independent line-cardioid and figure-ofeight condenser elements
- Switchable low-frequency roll-off
- Switch selection of non-matrixed M-S mode and two internally-matrixed left/ right stereo modes
