Audio Technica BP40 Large-Diaphragm Dynamic Broadcast Microphone

The BP40 Dynamic voice microphone provides natural sound reproduction for a variety of applications - radio, recording, post production ... thanks to its hypercardioid providing optimal isolation of the sound source and excellent off-axis rejection. The 37mm capsule with a patented "floating edges" design optimizes the surface of the membrane and maximizes performance, while the humbucking coil (for noise compensation) prevents the risk of electromagnetic interference (EMI) (generated by the video monitors, power supplies, etc). Due to its robust, all metal construction, the BP40 will be ideal in broadcast environments.

“Large Dynamic Membrane”

First broadcast microphone designed by Audio-Technica, having a wider dynamic diaphragm, dedicated to radio broadcasting and studio post production.

“A Radio Sound”

With its 37mm diameter dynamic capsule, the BP40 is very sensitive to plosives and retains very mild transients. Moreover, its multilayered windscreen guarantees high efficiency against "pops", which makes it ideal for radio studios and post-production studios. The optimized positioning of its capsule preserves an important vocal presence, even remotely.

“Fully Metallic Robust Construction”

Robust, all metal construction, ideal for use in professional broadcast environments.

Large Dynamic Capsule

The Ø 37 mm capsule of the BP40 has a patented "floating edges" construction which optimizes the surface of the membrane and maximizes performance.

Humbucking Coil

The Humbucking voice coil prevents the risk of electromagnetic interference (EMI) caused by video monitors, power supplies, etc).

Rich and Natural Sound

The BP40 Voice broadcasting microphone offers a capacitor-like rich and natural sound, thanks to a dynamic large-diaphragm design.
