Applications:
The PolarChoice PC Sat is acoustically designed for
high-quality sound reinforcement and broadcast applications.
The frequency response is tailored for wide-range sound
reproduction with very natural sound pick-up for either distant
or closeup use. The PolarChoice PC Satellite can be used on
lecterns, podiums, desks, table-tops, or other applications.
To maximize gain-before-feedback, the PolarChoice's three
directional polar patterns allow the user to pick the directional
polar pattern for optimum effect. For those applications where
gain-before-feedback is not a problem, an omnidirectional
pattern is included. Applications requiring speaking close
to the microphone at podiums, lecterns, or pulpits normally
require a windscreen (included) to control breath noise and
P-popping or, in some cases, wind noise from circulating air.
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 Satellite: PC Sat-5, PC Sat-12, PC Sat-18
The microphone shall be a free-standing, wireless, table-top
microphone, and shall produce a high degree of output
signal quality despite the possible near-field presence of
RF (Radio Frequency) devices such as cell phones. The
base will have an integral 4-pin TA4F connector, which
interfaces directly to one of the following wireless microphone
bodypack transmitters: Electro-Voice RE-1 or RE-2, Telex
FMR-1000, FMR-500 or Safe-1000. The microphone shall
have four selectable polar patterns: omnidirectional, cardioid,
supercardioid, and hypercardioid. The mic element is a
back-electret condenser type with a frequency response
of 50Hz to 20kHz. The microphone shall have a nominal,
balanced output impedance of 1000 Ohms. The microphone
will have a switchable high pass filter to roll off low
frequencies. The microphone shall have an output level
of 15.8 mV/Pascal, and outputs shall not be appreciably
affected by the following temperature and humidity extremes:
-29°C to 74°C (-20°F to 165°F) when the relative humidity
is 0–50%; -29°C to 57°C (-20°F to 135°F) when the relative
humidity is 0–95%. Dimensions shall be 231mm (9.1in.) long
(PC Sat-5), 373mm (14.7in.) long (PC Sat-12), and 526mm
(20.7in.) long (PC Sat-18) with a maximum head diameter
of 14.6mm (0.58in). The PC Sat-5 microphone shall include
a 175mm (6.9in.) gooseneck. The PC Sat-12 microphone
shall include a 318mm (12.5in.) gooseneck. The PC Sat-18
microphone shall include a 470mm (18.5in.) gooseneck. The
gooseneck will be attached to a base that has a top mounted
push-button, and a status LED which lights when audio is
active. The push-button will be configurable for push on/off,
or push-to-mute and push-to-talk operation. Furthermore,
when the push-button is set for push on/off operation, the
status of the microphone when power is initially applied can
be programmed to be either on or off. All controls except
for the push button are accessible from the bottom of
the microphone base, when the bodypack is not installed.
The microphone base shall be of metal construction. The
microphone will include an external windscreen and antenna
guide. The microphone shall have a nonreflecting black
finish. The Electro-Voice PolarChoice PC Sat- 5, PC Sat-12, or
PC Sat-18 is specified.
