Audio-Technica ( Iron Triangle ) AT897 ultra- directional condenser microphone

Audio-Technica ( Iron Triangle ) AT897 ultra- directional condenser microphone

Product Features :

Designed for video production and broadcast interviews (ENG / EFP) audio radio design.

Shorter length design (279mm), can be installed in small digital camera.

Smooth, natural radio performance and superior audio quality.

Provides ultra- narrow angle pointing performance , giving the effect of long-distance radio .

From the microphone to the rear sides have excellent noise immunity .

With a high-pass filter switch.

You can use a battery or phantom power .

Product description :

AT897 microphone requires 11V to 52V phantom power using a 1.5V AA battery or when using phantom power , you can not install the battery.

XLRM XLR output of the microphone is low impedance balanced output microphone audio signals ultimately to the 2nd and the 3rd pin male XLR output , and Pin 1 is ground ( shield ) connection. Positive phase output phase will be located on level 2 pins.

Built-in high -pass filter circuit can be easily from a flat frequency response at 80Hz or less open to radio attenuation effect , the application of high-pass filter can reduce radio frequency noise environments ( such as external Qi car engine sound, the air conditioning system of the wind , etc.) room reverberation and mechanically coupled vibrations .

RoHS compliant microphon

e in the EU directive on hazardous substances .
