Astatic 930VP User manual

Description
The ASTATIC 930VP is a superior, low noise, multi-pattern surface mounted
boundary microphone. The 930VP is equipped with a multi function mute and
switch selectable high pass filter. It is ideal for use on altars, conference tables,
stage floors, or television production.Also available in white (930VPW).
The 930VP's electronics features an advanced transformerless design, that is self
contained to eliminate the need for mounting any external boxes. The 930VP
offers a continuously variable polar pattern. Choose cardioid, super cardioid,
figure of eight, omni-directional, or any pattern in-between.You no longer need
to guess which polar pattern will provide the best gain before feedback. Just dial
in the best polar pattern at installation time. The 930VP contains a soft touch
membrane mute switch. This momentary touch mute switch can be configured
for push-to-talk, push-to-mute, or push on/off. In the push on/off mode, the
930VP can be configured to power up either on or off. In multiple microphone
applications, choose which microphones are live when the system is turned on.
An LED indicates when the microphone is on. The 930VP is equipped with a
switch selectable 12 dB per octave high pass filter that is perfect for eliminating
low frequency rumble.
The die cast zinc base and perforated steel screen construction makes this
microphone extremely rugged. The foam filter located under the steel screen
suppresses pops and wind noise. The 930VP can be permanently mounted on
most flat surfaces using the two mounting holes located on the bottom of the
microphone. When mounted on a flat surface, the 930VP will take advantage of
the "boundary effect" increase in signal to noise ratio. The 930VPcomeswith30

professional XLR connector.

Architect's and Engineers' Specification
The microphone shall be anASTATIC 930VP. The microphone shall be a miniature dual
electret boundary microphone. The frequency response will be 40Hz - 15KHz. The
microphone shall have a continuously adjustable polar pattern.
Theoutput level of the 930VPshall be -32dBV (25mV)@1Pa.The microphone will have a
miniature 3 pin connector and be supplied with a 30 foot cable that has a mating connector
on one end and a professional 3 pin XLR type connector on the other end. The microphone
shall have a switch selectable high pass filter with -3dB at 80 Hz and slope of 12dB per
octavewhen enabled. The microphone shall havealocally controlled mute that willprovide
greaterthan 60dB of attenuation when enabled. Themuteshallbe configurable for normally
muted / momentary push-to-talk, normally on / momentary push-to-mute or latch on / latch
off operation. When configured for latch on / latch off operation, the microphone shall be
configurable to either power up on or power up off. The microphone shall have a red LED
that will indicate if the microphone is on or off. The microphone will operate from
