The microphone shall be a screw-on cardioid capsule that mates with the AKG Discreet Acoustics Modular Series. The microphone shall accept phantom powering over the universal range from 9 to 52 volts dc. The response shall be flat on-axis from 150 Hz to 6 kHz (±2 dB), with a low frequency rolloff below 150 Hz that reaches –10 dB at 50 Hz, and response at 20 kHz that is no more than –4 dB, relative to the midband response. The microphone shall have a sensitivity no less than 20 mV/Pa (–34 dBV), and the total harmonic distortion (THD) at an operating acoustical level of 125 dB shall be no greater than 1%. The electrical impedance shall be no greater than 600 ohms. Electrical mating contacts for mounting the microphone shall be gold plated for positive, trouble free operation over long periods. The microphone shall be the AKG CK 31. Net/shipping weight: 5/88 g (0.17/3.1 oz.).
