accessories to suit all types of application.
Summary
The microphone is virtually unaffected by handling noise due to its
lightweight 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.
