Audio Technica BP40


Audio-Technica’s brand new BP40 large-diaphragm broadcast microphone is to receive its Prolight+Sound debut at this year’s event between 12-15 April.

A dynamic vocal microphone with rich, natural condenser-like sound for a variety of applications – including radio, overdubs, post-production and more – the BP40’s hypercardioid polar pattern provides isolation of the desired sound source and maximum off-axis rejection when working in close production environments. Its optimised capsule placement helps maintain a commanding vocal presence even at a distance, while the multistage windscreen provides superior internal pop filtering. It also includes a switchable 100 Hz high-pass filter to provide even more pop protection.

The BP40’s 37mm diaphragm features patented floating-edge construction that maximises diaphragm surface area and optimises overall diaphragm performance, while the humbucking voice coil prevents electromagnetic interference (EMI) (from video monitors, AC power etc). The microphone’s design, inspired by the visual representation of a waveform, features rugged, all-metal construction for dependable use in professional broadcast environments. The BP40 comes standard with the AT8483 mounting clamp, while for additional protection from noise, shock and vibration the optional AT8484 shock mount is available separately.
