Adjusting the sensitivity (A)
The microphone sensitvity can remain unchanged (0) or
be reduced by 10 dB or 20 dB. The latter is recommended
when there is a risk that the microphone or subsequent
microphone input is overmodulated, e.g. due to high
sound pressure levels from drums, brass instruments, etc.
Note:
We recommend that you mute the corresponding
microphone channel on the mixing console before
connecting and disconnecting the microphone cable,
switching on and off the phantom powering or setting
the switches (see figure above).
