Audio-Technica BP4073 Shotgun Microphone

Overview
Feature

The BP4073’s high sensitivity allows it to produce a strong output without requiring extreme gain at your mic preamp. With a selectable low-cut filter and a -10 dB pad, the BP4073 is capable of delivering clear, distortion-free sound due even on intensely loud sound sources. Plus, its full-spectrum frequency response utilizes a gentle increase in high frequencies to enhance intelligibility.

The rugged aluminum alloy housing ensures rugged dependability while maintaining an ultralight weight that won’t burden your boompole or camera, and the included accessories accommodate mounting the BP4073 to a mic stand, boompole, or camera-mount microphone holder.

Rivals Long-Tube Shotgun Microphones

Though only approximately 9.2″ long, the BP4073 offers the directivity of microphones up to 50% longer than it. This is accomplished through the use of a special Audio-Technica design that grants the BP4073’s interference tube a narrow acceptance angle.

Broadcast-Quality Sound

The BP4073 was built to produce broadcast-quality sound. Its direct-coupled balanced output provides clean signal even in high-output conditions; the balanced topology also allows longer cable runs than typical unbalanced camera-mount mics afford.

The supercardioid polar pattern yields focused on-axis directionality with maximum rear-entry sound rejection. Its low self-noise of 13 dBA and highly sensitive condenser element communicate detailed audio unburdened by the hiss that plagues many low-cost microphones.

Customizable Tone

Activate the 80 Hz low-cut filter to reduce low-frequency noise from common sources such as air conditioners and traffic. Switch on the -10 dB pad to attenuate the input level when loud sound sources threaten to distort your recording.

Phantom Powered

Thanks to its 3-pin XLR output and 48 VDC phantom powering, the BP4073 is compatible with a variety of handheld audio recorders, field recorders, and mixer adapters, as well as built-in preamps on many camcorders and cinema cameras.

Ideal for Boompole Mounting

The BP4073 includes a mic clip for easy placement on a mic stand or boompole. Alternatively, mount the BP4073 in the Audio-Technica AT8415 shockmount (available separately) to impede the transfer of vibrations between your boompole and the mic. The BP4073 also includes two rubber O-rings that expand the microphone’s diameter to fit the larger mic holders found on many high-end cameras.

Windscreen Minimizes Wind Noise

The BP4073 has a foam windscreen to reduce unwanted wind noise from breezes, fans, heaters, and air conditioners. Enhanced attenuation of wind noise is possible with the addition of an optional furry windshield such as the Saramonic TM-WS1.

For maximum reduction of handling noise and wind noise in indoor or outdoor environments, consider the separately available Rycote Windshield Kit 4, a complete windjammer, windshield, and shockmount suspension system.
