Introduced at the 2015 NAB Show in Las Vegas, Audio-Technica’s BP40 large-diaphragm dynamic broadcast microphone delivers big, condenser-like sound from a hassle-free dynamic design. The microphone is intended for use in radio, overdubs, post-production, podcasting and other broadcast applications.
Writing in Radio World, Michael T. Synnott praises the BP40 for a “big, bold full-frontal sound” that is obtainable in nearly any environment, thanks to the microphone’s hypercardioid polar pattern. Synnott likens the mic’s capacity for isolating the desired sound source to a “cone of silence,” concluding that it is the microphone’s “exceptional off-axis rejection that makes the BP40 a winner.”
Yet the BP40 has much more to offer than just its ability to reject off-axis noise. The microphone’s large diaphragm features Audio-Technica’s patented floating-edge construction, which was created especially for the BP40 to maximize diaphragm surface area and optimize overall diaphragm performance. Additionally, the microphone is outfitted with a humbucking voice coil to prevent the electromagnetic interference that is all too common in today’s monitor-heavy studios, and with an optimally placed capsule to maintain commanding vocal presence, even when the speaker is not right up on the microphone. A multistage windscreen provides superior internal pop filtering.
“It’s the multistage windscreen and the deep capsule placement that sets the BP40 apart, way apart, at the head of the pack, in my ears,” writes Synnott. “[It has a] natural depth, rich and rounded, in the 300 Hz to 3 kHz range that the human brain finds so attractive. It’s where the crooners pitch their love songs.” Read the full review.
To ensure that attractive, articulate vocal character, the BP40 comes equipped with a switchable 100 Hz high-pass filter to combat excessive low-end and provide additional pop protection. The microphone’s design, inspired by the visual representation of a waveform, features rugged, all-metal construction, and comes standard with the AT8483 mounting clamp. For additional protection from noise, shock and vibration, the optional AT8484 shock mount is also available separately. The U.S. street price of the BP40 is $349 and the optional AT8484 shock mount is $99.
