“two condenser capsules”

The BP4029 is equipped with two independent electret capsules, one configured as narrow cardioid and the other configured in figure of eight MS mode (central-lateral) with provision for adjusting the width of the stereo image in postproduction or outside by means of a matrix mixer.
“Two stereo modes”

With the BP4029 you can choose between a wide sound recording angle (LR-W) - whereby the microphone captures more ambient noise, or a narrow sound recording angle (LR-N) where the rejection is greater and ambient noises are mitigated.
“Compact and lightweight”

The BP4029 is manufactured from a lightweight but very sturdy aluminum, which can be heavily used in harsh environments. Its length is 380mm and it weighs 142g, making it ideal for installing on a boom. If its size were to be troublesome on certain cameras, it can also be used on a stand to capture distant sound sources.
