The BP40 is a large-diaphragm dynamic broadcast microphone engineered for on-air radio, podcast recording, and voice-over production, delivering the warmth and presence of large-diaphragm condenser designs in a dynamic capsule that requires no phantom power and handles the high ambient SPL levels common in broadcast control rooms. Its hypercardioid polar pattern provides excellent off-axis rejection for close-talking broadcast use, reducing room reflections and background noise picked up from the sides.

Large-Diaphragm Dynamic for Broadcast

A large-diaphragm moving-coil element gives the BP40 a fuller, more present sound than conventional dynamic broadcast microphones, capturing low-frequency body and upper-midrange presence that translates well on radio and streaming platforms. The dynamic capsule tolerates close-proximity talking technique — essential for radio and podcast broadcasters — without requiring the gain management that condenser microphones with proximity effect can demand.

Hypercardioid Pattern and Noise Rejection

The hypercardioid polar pattern narrows the acceptance angle compared to cardioid, providing higher gain-before-feedback and more effective side rejection in control rooms with multiple talkers, monitor speakers, and surface reflections. This tight pattern suits broadcasters who position the microphone off-axis from studio monitors for live acoustic monitoring during recording.

Integrated Shockmount and Build Quality

The BP40 features an integrated internal shockmount that decouples the capsule from mechanical vibration transmitted through the microphone stand or boom arm, reducing low-frequency thump and handling noise. The robust all-metal construction suits the demanding environments of daily broadcast production use.
