The Audio-Technica BP4025 is a professional stereo condenser microphone designed for broadcast, professional recording, and field use. It features a compact and rugged design, offering high-quality audio capture with an XY stereo configuration, which ensures realistic sound reproduction and wide stereo imaging. The microphone utilizes two large-diaphragm capsules carefully positioned in a coincident arrangement to deliver accurate stereo sound with an immersive depth. Its frequency response ranges from 20 Hz to 17 kHz, allowing it to capture a broad spectrum of sounds with precision.

The BP4025 is equipped with a low self-noise level, making it suitable for capturing subtle ambient sounds in critical recording environments. It operates on phantom power, typically 11-52V DC, ensuring compatibility with a variety of recording equipment. The microphone's maximum sound pressure level is 138 dB SPL, allowing it to handle high-volume audio sources without distortion. Its output is a balanced, low-impedance (50 ohms) signal via a standard XLR connector, providing noise-free transmission over long cable runs.

Designed for durability, the BP4025 incorporates a robust metal construction, providing reliable performance even in demanding field conditions. It includes a switchable 80 Hz high-pass filter to reduce low-frequency noise and a 10 dB pad to manage loud sound sources effectively. The microphone's design emphasizes ease of use with various accessories, including a windscreen and a protective carrying case, enhancing its utility for outdoor and mobile recording applications. Overall, the Audio-Technica BP4025 is a versatile and high-performance microphone ideal for capturing nuanced stereo audio in both studio and field settings.
