Know before you buy
The BP4025 features two large-diaphragm capsules in a coincident X/Y configuration. This allows it to capture a realistic, wide stereo image, making it ideal for recording ambient soundscapes, live performances, or field environments where spatial depth is essential.
Yes, the BP4025 is designed for camera mounting, but it requires an XLR input. If your camera has a 3.5mm input, you will need an XLR-to-3.5mm adapter that provides phantom power, or you should route the signal through a professional field recorder or audio interface.
The BP4025 is built to handle high sound pressure levels up to 155dB when the 10 dB pad is engaged. This makes it a reliable choice for recording loud environments like concerts or industrial settings without worrying about signal distortion.
The switchable low-frequency roll-off filter helps you reduce unwanted rumble, wind noise, or low-end vibrations during recording. It is particularly useful when you are capturing audio outdoors or in environments with significant HVAC noise.
No, the BP4025 operates exclusively on phantom power (11-52V DC). You must ensure your camera, mixer, or audio interface is capable of providing phantom power through the XLR connection to operate the microphone.
While it is compact enough for camera mounting, its 9.5 oz weight and professional XLR connectivity make it best suited for use on a camera shoe mount, a boom pole, or a tripod. It is a robust choice for professional field production where high-fidelity stereo capture is the priority.
