Audio-Technica Debuts BP40 Large-Diaphragm Dynamic Broadcast Microphone

May 11 2015, 04:00
Audio-Technica debuted its BP40 Large-Diaphragm Broadcast Microphone, a dynamic vocal microphone with rich, clear, natural condenser-like sound for a variety of applications including radio, overdubs, post-production, podcasting, and more.
Audio-Technica’s new BP40 Dynamic Broadcast Microphone with AT8484 Shock Mount (available separately).

The microphone’s hypercardioid polar pattern provides isolation of the desired sound source, and maximum off-axis rejection when working in close production environments. Its optimized 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 large diaphragm features patented floating-edge construction that maximizes diaphragm surface area and optimizes overall diaphragm performance, while the humbucking voice coil prevents electromagnetic interference (EMI) (e.g.,,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, and for additional protection from noise, shock and vibration, the optional AT8484 shock mount is available separately.

The BP40 specifications also state a frequency response from 50 to 16,000 Hz with a low-frequency roll-off switch from 100 Hz, 6 dB/octave. Open circuit sensitivity is –48 dB (3.9 mV) re 1 V at 1 Pa with an impedance of 450 Ω. It will be available July 2015 for $349. The optional AT8484 shock mount will also be available July 2015 for $99.
