Audio-Technica BP4027 Long Video Microphone

The BP4027 is a stereo condenser microphone designed for location sound recording, featuring a coincident X/Y capsule arrangement with fixed 90° capsule orientation for natural, phase-coherent stereo imaging. Built for demanding field conditions, it provides accurate stereo recording of ambience, music, effects, and dialogue in a single compact housing that accepts both phantom power and battery operation.

X/Y Coincident Stereo Design

The two cardioid capsules are mounted in a true coincident X/Y configuration at a fixed 90° angle, eliminating time-delay artifacts and ensuring mono-compatible stereo output. The coincident arrangement provides a stable, predictable stereo image that translates accurately between stereo playback systems and collapses cleanly to mono for broadcast applications.

Dual Power Operation

The BP4027 operates on standard phantom power or an internal 1.5V AA battery, maintaining consistent performance in remote field recording scenarios without access to external power. The battery life is sufficient for extended field sessions, making the BP4027 a self-contained stereo recording solution for nature, documentary, and location sound work.

Weather Resistance and Rugged Build

The BP4027 features a robust metal housing resistant to temperature variation and light humidity encountered in field recording environments. The standard shock mount thread accepts field wind protection systems, and the balanced XLR outputs connect directly to portable recorders, mixers, and camera audio inputs.
