The microphone shall be a fixed-charge condenser with a MicroLine polar pattern and a
frequency response of 30 Hz to 20,000 Hz. It shall be capable of accepting optional interchangeable
elements for additional polar patterns. It shall operate from an external 9V to 52V DC phantom
power source. Nominal open-circuit output voltage with the included power module shall be
15.8 mV at 1 kHz, 1 Pascal. Output shall be low impedance balanced (200 ohms).
The microphone shall have a permanently-attached 9.8' (3.0 m) miniature cable with a
pigtail output. The pigtail output shall connect to a power module via internal solderless screw
terminals. The power module shall include a switch for low-frequency roll-off and shall terminate
in a 3-pin XLRM-type output connector.
The microphone shall be a small-diameter alternating gooseneck design, with an overall
length from 20.28" (515.0 mm) to 22.83" (580.0 mm). Head diameter shall be 0.31" (8.0 mm).
The microphone shall include a
microphone desk or floor stand. A
installation to a mounting surface. The microphone weight shall be 3.9 oz (110 grams) without
cable. Finish shall be low-reflectance black.
