AKG C391B [16/64] Description

Description

The C 391 B system consists of a universal powering/output module

(SE 300 B), several microphone capsules and readily-interchangeable

accessories to suit all types of application.

Summary

The microphone is virtually unaffected by handling noise due to its

ightweight diaphragm. Additional features include the all-metal

housing, which makes it less susceptible to HF interference, as well as

its trouble-free operation in almost all situations due to its conservative

and reliable design.

The switchable 10 dB attenuation of the output signal is a major benefit

at high sound pressure levels (i.e. high-powered sound sources) and

when the input stages of amplifiers or mixing desks have lower

maximum input levels. If this option was not available, these connected

stages would be overamplified without being able to fully control the

microphone.

The switchable bass cut filter of the microphone also helps to suppress

low-frequency distortion, such as rumble or wind noises, that cannot

be controlled. The filter slope is approx. 12 dB/octave with the corner

frequency (-3 dB point) lying at approx. 75 Hz.
