AT915AMRx/ML Specifications   Architects and Engineers Specifications The microphone shall be a fixed-charge condenser with a MicroLine â 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 5/8"-27 threaded flange to mate with the threads of a standard microphone desk or floor stand. A 5/8"-27 threaded stud shall be provided for permanent installation to a mounting surface. The microphone weight shall be 3.9 oz (110 grams) without cable. Finish shall be low-reflectance black.
