Microphone condensor measurement Phaselab Reference with a 6 mm condenser capsule type. It has an omni-directional polar pattern and offers a frequency response of 18 Hz - 20 kHz. The impedance is 200 ohms, and the sensitivity at 1 kHz into 1K ohm is 10mV/Pa (-40 dBV, re. 0 dB = 1V/Pa). The microphone can handle a maximum SPL for 1% THD @ 1 kHz of 127 dB and has a S/N ratio of 70 dB A-weighted. It features a gold-plated XLR connector and requires +48V phantom power.
