Virtual Return Feedback Suppressor Block - Extron electronics DMP 128 Plus User Manual

Virtual Return Feedback Suppressor Block

Use the feedback suppressor when there is an indication of feedback during live operation.
Dynamic filters automatically detect feedback on a live mic channel, and engage a set of
up to 5 fixed and 15 dynamic filters to counteract feedback at the detected frequencies.
The dynamic filters act in a "first in, first out" rotation. If all 15 dynamic filters are employed
and an additional feedback frequency is detected, the first feedback frequency detected is
overwritten.
To avoid a new feedback frequency overwriting a previously detected frequency, up to 5
dynamic filters can be transferred into fixed filters. Once a dynamic filter is transferred into a
fixed filter, it can only be overwritten by manually assigning a new frequency to the filter.
