Audio-Technica BP4027 Stereo shotgun microphone, 15.0" long

Product Overview

The Audio-Technica BP4027 is a stereo shotgun microphone engineered for high-end broadcast and production recording. It houses independent line-cardioid and figure-of-eight elements in a Mid-Side (M-S) arrangement with switch-selectable internal matrixing, so recordists can output left-right stereo or discrete M-S signals. This professional stereo shotgun microphone captures directional dialogue and a controllable stereo image in one body.

Product Description

The Audio-Technica BP4027 combines a directional line-cardioid mid element with a figure-of-eight side element to deliver flexible stereo capture for film, television, and field recording. Its 380 mm (15.0″) body mounts on a boom or stand for dialogue, effects, and ambience.

Internal matrixing lets the operator select a wide stereo pattern (LR-W) for more ambience or a narrow pattern (LR-N) for greater rejection, or pass discrete Mid-Side signals for post-production control. A switchable low-frequency roll-off reduces unwanted rumble in the field. Browse more Audio-Technica microphones for broadcast and production at Creation Networks.

Frequently Asked Questions

What is Mid-Side (M-S) recording on the BP4027?
M-S uses a directional mid element plus a figure-of-eight side element. The microphone can matrix these into left-right stereo, or output discrete Mid-Side signals for adjustment in post.

Can I change the stereo width?
Yes. Switch-selectable matrixing offers a wide pattern (LR-W) with more ambience and a narrow pattern (LR-N) with greater rejection, or discrete M-S output.

What power does it require?
It operates on 48V DC phantom power.

Does it have a low-cut filter?
Yes. A switchable low-frequency roll-off helps minimize unwanted low-frequency noise in the field.

How does it mount for production work?
It mounts on a boom or stand to capture directional dialogue, effects, and a controllable stereo ambience.

Is warranty and support available?
Audio-Technica's manufacturer warranty applies, and Creation Networks assists commercial AV buyers with selection and integration.
