Astatic Variable Polar Pattern Miniature Gooseneck - GN20VPD
The integral 80Hz, 12dB/octave high-pass filter removes unwanted low-frequency energy to improve intelligibility. The cable can easily be made to exit the bottom or the rear of the stand. The GNVPD series features logic I/O functions that can be utilized with automatic mixers, teleconferencing systems and control systems. The logic input can remotely control the LED as well as membrane switch activation. The membrane switch working with or bypassing the microphone's mute activates the logic output. Bypassing mute is particularly useful with teleconferencing systems that mute the microphones after the echo cancellation block. The exact mode of operation can be set with the DIP switch on the underside of the desk stand. The GNVPD has a continuously-variable polar pattern so it can shorten the list of products an audio system designer needs to consider when gooseneck condenser mics are specified. The installer can precisely tailor the polar pattern for the best performance depending upon the application or environment. The GNVPD is primarily designed for speech and vocal pickup in governmental, institutional, and business applications.
