GN15VPD/GN20VPD
Continuously-variable Pattern, Condenser, Mini-gooseneck Microphone with
Integrated Desk Stand, Programmable Switch, LED and Logic Interface
Description
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. 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.

Logic Interface Details
The logic input, in effect, consists of a 40K ohm pull-up resistor
to the internal microprocessor power supply (1.3V). Pulling
the logic input to ground will activate the logic input.
The logic output, in effect, consists of the open collector of
an NPN transistor. The emitter of this transistor is connected
to ground. When the logic output is activated, current will
flow from the logic output through the transistor to ground.
It is recommended that the pull-up resistance value at the
receiving circuit be kept as high as possible to minimize the
current flow into the logic output. High currents can induce
switching noise into the audio. Absolute maximum current
into the logic output is 50mA.
