LINE + GRADIENT CONDENSER MICROPHONE

- Designed for video production and broadcast (ENG/EFP)

audio acquisition

- Extremely short length (175mm) 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

The AT875R requires 11V to 52V DC phantom power for

operation.

Output from the microphone’s 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 preamplier to

avoid overloading sensitive input stages.

The microphone is RoHS compliant–free from all substances

specied in the EU directive on hazardous substances.

Avoid leaving the microphone in the open sun or in areas

where temperatures exceed 43°C for extended periods.

Extremely high humidity should also be avoided.
