Included Accessories
....................................30' [9m] cable,
foam windscreen,
adhesive “Astatic” security cover.
This microphone will be a mini-gooseneck condenser type
with a permanently-attached desk stand a programmable
membrane switch. The frequency response will be 80-18KHz.
The microphone will have a continuously-variable polar
pattern. The membrane switch will be programmable to
work as push-to-talk, push-to-mute, on/off, and activate a
logic output for remote functions. The microphone will have
a logic input that can be configured to remotely control the
LED or the membrane switch.
The sensitivity of the microphone will be –36dBV (16mv)
@ 1Pa. The microphone will have a miniature 4-pin TB4M-type
connector on the underside of the desk stand allowing for
rear or bottom exit. A 30' [9m] miniature 4-pin female to
3-pin male XLR cable will be provided. The cable will have
4 conductors within a shield. The logic input and the logic
output wires will not be connected to the 3-pin male XLR
when shipped from Astatic.
The desk stand will contain the microphone’s electronics,
variable-pattern control, membrane switch and a DIP switch
for programmable functions. The microphone will operate
on P12, P24 or P48 standard phantom power consuming
4mA.
The microphone element and electronics will be enclosed
in a radio frequency resistant housing meeting or exceeding
EN55103-2. The GN15VPD will be 15" [381mm] in overall
length and 4 -1/2" [115mm] in diameter at the base. The
GN20VPD will be 20" [508mm] in overall length and 4-1/2"
[115mm] in diameter at the base. The GN15VPD and
GN20VPD will have a durable matte-black urethane finish.
A foam windscreen, control cover and mounting screws
will be supplied.
The Astatic model GN15VPD or GN20VPD is specified.

Continuously-variable Pattern Condenser Mini-gooseneck Microphone with
Integrated Desk Stand, Programmable Switch, LED and Logic Interface

The GNVPD microphone has an integrated membrane switch on the desk
stand. This membrane switch can be programmed using the DIP switch on
the underside of the microphone (see diagram). The microphone will come
from the factory in the “Power Up On” mode.
Push to Talk (momentary mode):
A momentary press on the membrane switch (or a closure to ground on the
logic input) will activate the microphone, close the logic output and turn the
LED on.
Push to Mute (momentary mode):
A momentary press on the membrane switch (or a closure to ground on the
logic input) will mute the microphone, open the logic output and turn the
LED off.
Power Up On (latching mode):
The microphone is active, the logic output is closed and the LED is on when
phantom power is first applied. A momentary press on the membrane
switch will toggle the microphone mute, the logic output and the LED.
Power Up Off (latching mode):
The microphone is muted, the logic output is open and the LED is off when
phantom power is first applied. A momentary press on the membrane
switch will toggle the microphone mute, the logic output and the LED.
Remote Mode:
1.
The LED will illuminate when the logic input is grounded.
2.
The logic output will close when the membrane switch is pressed.
3.
The audio will remain un-muted.
Polar pattern Adjustment
1.
Set the desired polar pattern by turning the dial on the underside
of the microphone.
2.
Cover controls with the provided adhesive security label if desired.
