Architect's and Engineers' Specification
The microphone shall be an ASTATIC 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.
The output level of the 930VP shall 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
octave when enabled. The microphone shall have a locally controlled mute that will provide
greater than 60dB of attenuation when enabled. The mute shall be 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
standard 48V phantom power with a current consumption of less than 6 mA.
The dimensions of the microphone shall be 5 1/2" long, 3 1/2" wide, and 15/16" high. The
weight shall be 4.6 oz not including the cable. The microphone will have a durable urethane
painted finish. The microphone will be black with a black cable or white with a white
cable.
The ASTATIC Model 930VP is specified.
