PC Boundary
The microphone shall be a low profile boundary microphone. The microphone 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 figure 8. 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 110.4 mm (4.34 in.) long by 64.6mm (2.54 in.)
wide by 25.8mm (1.02 in.) high. The microphone will feature a top mounted membrane switch and a status LED that
lights when audio is active. The membrane switch will be configurable to operate in either momentary or toggle mode.
When the microphone is set in momentary mode, the membrane switch 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
and grille shall be of metal construction. The microphone shall have a
nonreflecting black finish. The Electro-Voice PC Boundary microphone is
specified.
