Features
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.
AT875R Features:
- Designed for video production and broadcast (ENG/EFP) audio acquisition
- Extremely short length (under 7") ideal for use with compact digital cameras
- Provides the narrow acceptance angle desirable for long-distance sound pickup
- 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.
