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 Series” installation 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.
