Architectural & Engineering Specs:
Frequency Response:
Polar Response:
PolarChoice Desktop: PC Desktop-5, PC Desktop-12, PC Desktop-18
The microphone shall be a freestanding, tabletop microphone. The base will have a 10-foot integral 5-conductor (2-conductor shielded)
cable terminated in a 3-pin XLRM connector. The microphone shall have four selectable polar patterns: omnidirectional, cardioid,
supercardioid, and hypercardioid. The mic will use a pair of back-electret condenser elements with a frequency response of 50 Hz to 20
kHz. The microphone shall have a nominal, balanced output impedance of 200 ohms. The microphone will have a switchable high-pass filter
to roll off low frequencies. The microphone shall have an output level of 5.6 mV/Pascal and outputs shall not be appreciably affected by the
following temperature and humidity extremes: -29° to 74° C (-20° to 165°F) when the relative humidity is 0-50%; -29° to 57°C (-20° to 135°F)
when the relative humidity is 0-95%. Dimensions shall be 231 mm (9.1 in.) long (PC Desktop-5), 373 mm (14.7 in.) long (PC Desktop-12), and
526 mm (20.7 in.) long (PC Desktop-18) with a maximum head diameter of 14.6 mm (0.58 in). The PC Desktop-5 microphone shall include a 175
mm (6.9 in.) gooseneck. The PC Desktop-12 microphone shall include a 318 mm (12.5 in.) gooseneck. The PC Desktop-18 microphone shall
include a 470 mm (18.5 in.) gooseneck. The gooseneck will be attached to a base that has a top mounted push-button and a status LED that
lights when audio is active. The push-button will be configurable to operate in either momentary or toggle mode. When the microphone is set
in momentary mode, the push-button can be programmed to operate in either push-to-mute or push-to-talk mode. When the microphone is set
in toggle mode and power is initially applied, the status of the microphone can be programmed to be either on or muted. The microphone will
be capable of operation with automatic mixers by means of a configuration switch located on the bottom of the microphone. When the
microphone is in automatic mixer mode, normal LED and top push button functions are disabled. In automatic mixer mode, audio will always be
on, the top push button will only change the logic level on the microphone’s white wire, and a logic low level on the microphone’s orange
wire will cause the LED to illuminate. All controls except for the push button shall be accessible from the bottom of the microphone base. The
microphone base shall be of metal construction. The microphone will include an external windscreen. The microphone shall have a
nonreflecting black finish. The Electro-Voice PolarChoice™ PC Desktop-5, PC Desktop-12, or PC Desktop-18 is specified.
