AKG CK33 Capsule Module Microphone
Due to the narrow 95° pickup angle, the hypercardioid polar pattern is a good choice for all situations when noise typically arrives from the sides (especially in places of worship), where people talk into the microphone from greater distances, or where several talkers are grouped side by side. The body is identical to that of the CK 31 and CK 32.
Suitable Discreet Acoustics modules: all GN gooseneck modules, HM 1000 hanging module.
- Hypercardioid polar pattern
- 95° pickup angle
- Screw-on Capsule Module
- Highly efficient windscreen
The microphone shall be a screw-on hypercardioid 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 of the microphone shall be flat on-axis from 50 Hz to 20 kHz, with a 6 dB/octave rolloff below 200 Hz and response at 20 kHz that is no more than –6 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 of the microphone 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. Net/shipping weight: 5/88 g (0.17/3.1 oz.).
