The Audio-Technica BP4025 X/Y Stereo Recording Microphone is a specialized X/Y stereo field recording microphone.
The Audio-Technica BP4025 X/Y Stereo Recording Microphone is a professional stereo condenser designed for broadcast and high-end field recording. It utilizes large-diaphragm capsules in an innovative coincident configuration to deliver a realistic X/Y stereo image with significant spatial impact. This microphone provides the realism of a live sound field while maintaining a compact form factor suitable for various professional environments.
The BP4025 features a unique capsule arrangement that integrates large-diaphragm components into a smaller housing. This coincident configuration produces an accurate stereo image and ensures excellent channel separation. The design allows the microphone to capture high-fidelity audio with the spatial depth required for professional recording and broadcast applications.
Large-diaphragm capsules provide pristine sound quality and exceptionally low noise floors. The microphone includes integrated controls to adapt to different recording environments:
The compact and lightweight design makes the BP4025 ideal for camera-mount use and portable field recording. The microphone is fully RoHS-compliant, meeting EU directives regarding the reduction of hazardous substances. Its rugged build quality ensures reliability when used with professional audio and video equipment.
The BP4025 operates via phantom power, making it compatible with a wide range of professional mixing consoles and recording interfaces. The package includes one balanced cable that splits into two 3-pin XLRM-type connectors at the output for seamless stereo integration.
