Audio-Technica (iron triangle) AT897 super pointing capacitor

Audio-Technica (iron triangle) AT897 super pointing capacitive microphone Audio-Technica (iron triangle) AT897 super pointing capacitive microphone Features: Designed for film and television production and broadcast interview (ENG / EFP) audio radio. The shorter length design (279mm) can be installed in a small digital camera. Smooth, natural radio efficiency, and superior audio quality. Provides a narrow angle super point-to-pending performance, gives a remote radio effect. It has excellent anti-noise ability from both sides of the microphone to the rear. High pass filter switches are provided. You can use the battery or phantom power supply. Product Description: The AT897 microphone is required to use 11V to 52V phantom or 1.5V AA battery. When using an illusion, the battery can be installed. The XLRM card farmer output of the microphone is a low impedance balance output. The microphone audio signal is finally output with the 2nd and No. 3 of the mission of the mission of the mission, and the pin is connected to the ground (shield). The output phase will be placed on the 2rd pin at a positive phase level. The built-in high-pass filter circuit can easily respond to a flat frequency, open to the radio effect of attenuation below 80Hz, and the high-pass filter can reduce the low frequency noise in the radio environment (such as the outer 汔 汔 引 引, the air conditioning system of the air conditioner, etc.), Echo and mechanical shock in the room. The microphone is in line with the RoHS specification, which does not contain an EU-disabled hazardous substance.
