Audio-Technicas AT875R is designed for video production and broadcast (ENG/EFP) audio acquisition. Audio-Technicas shortest shotgun microphone, it mounts conveniently on a DV camcorder without adding noticeable heft, and is ideal for use with compact digital cameras. This high-performance microphone offers a narrow acceptance angle of line + gradient design. It also features smooth, natural-sounding on-axis audio quality and excellent off-axis rejection of sound arriving from the sides and rear of mic.

Excellent sound rejection from the sides and rear of mic
Tailored response minimizes camera and handling noise
Operates on phantom power only
RoHS compliantfree from all substances specified in the EU directive on hazardous substances
The AT875R requires 11V to 52V DC phantom power for operation. Output from the microphones XLRM-type connector is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground (shield). 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 AT875R assures useful output and an excellent match to most input sources. In some cases, however, an attenuator such as the Audio-Technica AT8202 may be required between the microphone and preamplifier to avoid overloading sensitive input stages.
