Setting Up And Use; Adjusting The Pre-Attenuation; Adjusting The Bass Roll-Off Filter; Maintenance - Beyerdynamic MC 930 Mode D'emploi

Setting up and Use

When the microphone is used outdoors or
for close vocal miking, we recommend to use the
WS 101 wind screen which can be fitted on the
microphone.

Adjusting the pre-attenuation

Without pre-attenuation the microphone
has a maximum SPL of 125 dB. At higher SPL a pre-
attenuation of 15 dB can be applied with the right
slide switch on the front of the microphone
(marked: -15 dB). The microphone can then handle
an SPL of 140 dB.

Adjusting the bass roll-off filter

When the microphone is used for close vocal
miking the low frequencies are pre-emphasised, this
is known as proximity effect. To compensate for
proximity effect, the microphone has on the front
(left) a switchable filter giving bass roll-off of
6 dB/Octave at 250 Hz.

Maintenance

For cleaning metal surfaces, use a soft, damp
cloth using only gentle cleansing agents (such as
washing-up liquid). Make sure that no water drops
into the microphone and do not use any solvent
cleaners.
Clean the WS 101 wind screen in clear, warm water.
It should be completely dry, before it is used again.
