AKG Acoustics Microphone CK 31 User Manual

CK 31  
Capsule Module  
Description  
The CK 31 is a cardioid modular screw-on capsule with  
smooth response from 50 Hz to 20 kHz. All 30-series  
capsules feature pre-polarized condenser elements with gold  
plated contacts to ensure reliable connections and trouble-  
free performance. The CK 31 capsule can be used with any of  
the Discreet Acoustics Modular Seriesinstallation modules.  
Each 30-series capsule has a dual layer windscreen; the dark  
gray outer layer disperses the impinging air stream while the  
inside layer smoothes the air stream before it reaches the  
diaphragm. This two-stage process efficiently reduces wind  
noise while maintaining acoustic transparency.
