d. take back the microphone’s volume at its normal
level.
Now the notch filters have been placed on the
frequencies where the feedbacks are more likely to
appear and, therefore, in case the microphone level is
raised during the performance, they will be able to
reduce them.
ATTENTION!!!
The d400’s ANTI-FEEDBACK in not able to eliminate
completely the feedbacks, but it can reduce the risk
that they happens during a performance. This
allows the use of the system at a higher level than
usual and also in critical conditions as, for example,
with the microphones placed in front of the
speakers or with moving microphones.
