Description
The AT875R is a fixed-charge condenser microphone with a line + gradient polar pattern. It is designed for video production and broadcast (ENG/EFP) audio acquisition. The microphone requires 11V to 52V phantom power for operation. The microphone’s highly directional polar pattern provides a narrow acceptance angle along with crisp, intelligible audio reproduction desirable for long-distance sound pickup.
The output of the microphone is a 3-pin XLRM-type connector. The microphone is enclosed in a rugged housing. The included AT8405a stand clamp permits mounting on any microphone stand with 5 /8″-27 threads. A windscreen, two o-rings, and a soft protective pouch are also included.
Operation and Maintenance
The AT875R requires 11V to 52V phantom power for operation. Output is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground (shield). The output phase is “Pin 2 hot”— positive acoustic pressure produces positive voltage at Pin 2.
To avoid phase cancellation and poor sound, all mic cables must be wired consistently: Pin 1-to-Pin 1, etc.
The high sensitivity of the microphone assures useful output and an excellent match to most input sources. In some cases, however, an attenuator may be required between the microphone and preamplifier to avoid overloading sensitive input stages.
Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110° F (43° C) for extended periods. Extremely high humidity should also be avoided.
Note: To use the microphone with a camera-mount microphone holder whose diameter is too large to secure the microphone, slide the two supplied o-rings onto the microphone handle, spaced so that one fits just in front of, and the other fits just behind, the rubber nubs inside the microphone holder. When the top of the microphone holder is closed and tightened down, the o-rings should hold the microphone securely in place.

FAQs Audio-Technica AT875R Microphone
Is phantom power required for the AT875R?
Operations and Upkeep For operation, the AT875R needs phantom power between 11 and 52 volts.
What is the Audio Technica AT875R’s frequency response?
Because of this, compared to omnidirectional mics used in most cameras, the AT875R is far more successful at picking up distant sources. Its frequency response from 90 Hz to 20 kHz automatically cuts down on troublesome bass frequencies from frequent sources like wind noise and highway rumbling.
What kind of microphone is the toughest?
Dynamic microphones are typically more durable than condensers, making them better suited for usage on stages.
What is a shotgun microphone used for?
In addition to vlogs and occasionally YouTube videos, shotgun microphones are a type of microphone that are widely utilized in film and television production. Shotgun microphones may pick up sound from a specific direction while excluding background noise since they are extremely directional.
What does Audio-Technica’s hear through feature do?
When requested, the hear-through capability, a switchable feature, enables you to hear ambient noise through your headphones as you listen to music. A built-in microphone is used by Hear-through to amplify ambient noise and concentrate on human sounds.
What is the audio’s frequency response spectrum?
20,000 Hz to 20 Hz
Which microphones from Audio-Technica are the best?
Certainly a versatile mic for the home studio, the Audio Technica AT2020. It sounds good on a variety of vocal and spoken voices. But with appropriate mic placement and EQ, it may also be utilized with a variety of instruments, particularly acoustic guitar.
What does Audio-Technica’s low latency mode mean?
When playing games or watching videos, this option shortens the sound delay. AAC will be used as the Bluetooth codec when low latency mode is enabled.
What microphone distance is ideal?
roughly 6 to 12 inches distant
What is a microphone’s range?
The distance between a microphone’s upper and lower limiting frequencies is referred to as its frequency range. The frequency range that can be covered by modern microphones ranges from about 1 Hz to 140 kHz.
A condenser microphone is what?
An extremely sensitive vibrating diaphragm is used by condenser microphones, which are recording devices, to capture sound. Since they can be used to capture virtually any instrument, condenser microphones are regarded as the most flexible recording studio microphones.
