Features

BP4073

short and lightweight, ideal for recording in the field

Created after intensive field research and from extensive user feedback, the BP4073 short shotgun microphone is ideal for creating a high quality audio sound recording. It is intended for documentaries, professional recordings in the wild, and theater sound reinforcement. Highly directional, the BP4073 has low self noise and extremely focused sound recording.

  • Short (233mm) shotgun microphone, designed for use in broadcasting, film/TV production and theater sound reinforcement applications
  • Its compact size and light weight (99g) allow it to be mounted on a camera or on a fishpole boom, keeping it out of shot
  • Highly directional, it perfectly captures all frequency ranges (20Hz to 20kHz)
  • Perfect intelligibility, even in noisy environments thanks to excellent off-axis noise rejection
  • The Double Wave Diaphragm proprietary technology offers high sensitivity with low self noise
  • Direct-coupled, balanced output ensures a clean signal even in high-output conditions
  • Innovative acoustic design provides same directivity as mics up to 50% longer
  • Switchable 80 Hz hi-pass filter & 10 dB pad
  • Rugged housing made of lightweight structural-grade aluminum alloy
  • Effective protection against mobile phone interference and other unwanted radio frequency
  • Comes with a foam windscreen

“Low-cut filter”

The low-cut position reduces sensitivity to ambient low frequency noise such as traffic noise, ventilation, reverberation of the room or mechanical vibrations transmitted through the recording device.

“Short ant lightweight shotgun mic”

Especially suitable for mounting on a fishpole boom or outdoors on professional camera, the BP4073 weighs only 99 grams and has a length of just 23.3 cm.

“High intelligibility”

Its very narrow directivity provides the narrow acceptance angle needed to capture far away sound whilst maintaining excellent off-axis noise rejection. The BP4073 guarantees very specific audio capture with high intelligibility.

Robust body

Robust microphone design made of lightweight aluminum alloy, which allows it to be positioned it on a boom, a camera or on a tripod.

Low-cut filter

Switchable low-cut filter for better insulation of unwanted noise.

Line + gradient

The BP4073 combines a directional capsule (gradient) and an interference tube to remove the sound from the rear.

Accessories

Comes with a clip, a foam windscreen, two O-rings and a protective carry case.
