EV Multi-Port Windscreen:
All PolarChoice microphones come with the exclusive EV Multi-Port
Windscreen. This unique one-piece ported design offers greatly
improved resistance to "P"-popping noise by creating a two-stage
filter that has an air space between the stages. This makes the
multi-port windscreen as effective as much larger traditional designs.
Architects' and Engineers' Specifications:
PolarChoice Desktop: PC Desktop-5, PC Desktop-12, PC Desktop-18.
The microphone shall be a freestanding, tabletop microphone with
a high degree of output signal quality despite possibly near-field
presence of RF (radio frequency) devices such as cell phones. 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.
