The AKG C391 B is a robust small-diaphragm condenser microphone. It consists of the SE300 B power module and the CK91 microphone capsule. The capsule has a cardioid polar pattern that effectively suppresses sound from the sides and rear. Instruments can thus be recorded uncolored and without crosstalk even in loud environments. The AKG C931 B delivers a natural, neutral sound with clear and brilliant highs.
To compensate for the proximity effect or to reduce low-frequency interference noise, there is a high-pass filter. Alternatively, the input sensitivity can be reduced by 10 dB. This allows the microphone to handle very high sound pressure levels without distortion.
The microphone capsule can be quickly changed if needed. Alternatively, AKG offers microphone capsules with polar patterns of omnidirectional, supercardioid, figure-eight, and shotgun. This allows flexible adaptation to any recording situation.
