Audio Technica - BP40
Audio-Technica BP40, large-diaphragm dynamic broadcast microphone designed for rich, natural vocal reproduction similar to that of a condenser microphone. It is ideal for professional broadcast environments thanks to its rugged metal construction. Its hypercardioid polar pattern improves isolation and reduces the risk of feedback. A switchable 100 Hz low-cut filter helps eliminate pops and background noise. The hum-canceling coil prevents electromagnetic interference (EMI). The floating-edge diaphragm design maximizes surface area and optimizes performance. This microphone delivers clear, articulate reproduction, even at a distance, thanks to optimized capsule positioning.
Presentation
- Design and Performance:
• The BP40 features a large-diaphragm design with a patented floating-edge construction, maximizing the diaphragm surface area and optimizing its overall performance.
• It incorporates a hum-canceling coil that prevents electromagnetic interference (EMI), ensuring a clean, noise-free signal.
• Its hypercardioid polar pattern provides excellent isolation, focusing on sounds coming directly in front of the microphone while reducing the pickup of ambient sounds and minimizing feedback. The acceptance angle is 100°.
• The switchable 100 Hz high-pass filter helps reduce unwanted low frequencies such as pops, handling noise, mechanical vibrations and ambient background noise, improving vocal clarity. The cutoff is 6dB/octave.
- Sound Quality and Usage:
• The optimized capsule placement maintains a clear and strong vocal presence, even when the speaker is far from the microphone.
• Its multi-stage internal windscreen provides superior pop filtering, preventing explosive noise in recordings.
• The BP40 is designed for clear and articulate vocal reproduction, making it ideal for a variety of broadcast applications.
• The microphone's frequency response is 50 to 16,000 Hz.
- Construction and Technical Specifications:
• The BP40 is constructed with rugged all-metal materials, ensuring reliable use in demanding professional broadcast environments.
• The microphone weighs 632 grams and measures 164 mm in length and 56 mm in diameter.
• The open circuit sensitivity is -48 dB (3.9 mV) re 1V at 1 Pa.
• The output impedance is 450 ohms.
• The output is a 3-pin XLRM type.
• It comes with an AT8483 mounting clamp for 5/8"-27 threaded microphone stands, a 5/8"-27 to 3/8"-16 threaded adapter, and a soft protective pouch. An AT8484 shock mount is available separately for added protection against vibration.
The BP40 is an excellent choice for broadcast professionals seeking exceptional sound quality, rugged construction, and advanced features for impeccable vocal capture.
