Audio-Technica AT875R Microphone Specification

The Audio-Technica AT875R is a short shotgun microphone designed for video production and broadcast applications. It features a highly directional polar pattern focusing on sound from the front while minimizing noise from the sides and rear, making it ideal for capturing dialogue and sound effects in challenging acoustic environments. The microphone operates on a frequency response of 90 Hz to 20 kHz, offering clear and natural audio reproduction with a smooth, tailored low-frequency roll-off to reduce ambient noise and rumble. Its compact size, measuring just 175 mm in length, makes it easy to mount on compact digital cameras or boom poles without obstructing the camera's view. The AT875R is powered by 11-52V phantom power, ensuring compatibility with a wide range of professional and consumer audio equipment. Its robust metal construction provides durability for field use, while the low self-noise of 20 dB SPL ensures high-quality audio capture with minimal hiss. The microphone has an impedance of 100 ohms and a sensitivity of -30 dB (31.6 mV) re 1V at 1 Pa, allowing it to capture subtle audio details with precision. The AT875R's rugged design is complemented by a foam windscreen that reduces wind noise during outdoor recording. With a weight of just 80 grams, it is lightweight and easy to handle, reducing fatigue during extended shoots. The Audio-Technica AT875R combines professional-grade audio performance with ease of use, making it a versatile choice for filmmakers, videographers, and content creators seeking reliable and high-quality audio capture solutions.

Audio-Technica AT875R Microphone F.A.Q.

How can I reduce background noise when using the Audio-Technica AT875R microphone?

To reduce background noise, ensure the microphone is pointed directly at the sound source, use a windscreen to minimize wind noise, and consider placing sound-absorbing materials around the recording area.

What is the best way to connect the AT875R to a DSLR camera?

To connect the AT875R to a DSLR, use an XLR to 3.5mm adapter cable and ensure the camera has an external microphone input. Consider using a preamp for better sound quality.

How do I properly maintain and clean the AT875R microphone?

Regularly clean the microphone body with a soft, dry cloth. Avoid touching the microphone capsule and keep it stored in a dry, dust-free environment when not in use.

Can the AT875R be used outdoors and in what conditions?

Yes, the AT875R can be used outdoors. It's advisable to use a windscreen or blimp to protect against wind noise and moisture.

What is the recommended power source for the AT875R microphone?

The AT875R requires phantom power, typically 48V, which can be supplied by most mixers, audio interfaces, or portable recorders.

How should the AT875R be positioned for optimal sound capture?

Position the AT875R with the front end facing the sound source and keep it at a distance of about 6-12 inches for optimal audio quality.

What troubleshooting steps can be taken if the AT875R is not picking up any sound?

Check all cable connections, ensure the microphone is receiving phantom power, and verify that the input channel on your recording device is not muted.

Are there specific accessories recommended for use with the AT875R?

Recommended accessories include a shock mount, windscreen, XLR cables, and a boom pole for increased flexibility in positioning.

How does the AT875R perform in different acoustic environments?

The AT875R performs well in controlled environments due to its directionality but may require additional noise reduction measures in echo-prone or noisy environments.

What should be done if the AT875R's audio output is distorted?

Reduce the input gain on your recording device, check for proper phantom power supply, and ensure the microphone is not positioned too close to a loud sound source.
