CAD ASTATIC GN20VPD- 20" Gooseneck Microphone,Variable Polar Pattern, Integrated Desk Stand

GN20VPD- 20" Gooseneck Microphone, Continuously Variable Polar Pattern, Integrated Desk Stand, CAD ASTATIC

The GNVPD is a series of dual-flex, continuously-variable polar pattern, miniature-gooseneck condenser microphones with:

• integrated desk stand, programmable membrane switch,
• LED, and logic interface.
• Continuously variable polar pattern, to adapt to the application or the environment
• 80Hz bass roll of filter
• LED
• membrane switch, PUSH, TALK MUTE

Special attention has been taken to design the GNVPD series to resist interference from devices such as cell phones and two-way communication devices.

• 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.
