Option Description
Enable Feedback
Cancellation
Check the check box to activate the Feedback Eliminator on this
processor channel.
Filter Bandwidth Bandwidth is determined by the specified Q factor. A lower Q creates a
filter that works across a wider frequency range. A higher Q utilizes a
narrower range.
Filter Depth Mode Locked: Filters are re-used. A replacement filter, with new settings and
increased filter depth is applied in place of an existing filter.
Unlocked: Adds a new filter at a specific frequency. No filters are
replaced, so this setting will count against the total number of filters
available.
Mode Choose Voice or Music, depending on the type of audio most
frequently used on this channel.
Note:
Voice Mode is the more aggressive setting.
Enable Ringing Elimination Allows the feedback eliminator to suppress ringing.
Note:
This setting adjusts slowly to eliminate ringing.
Run Setup Click to scan the audio channel for feedback loops and automatically
create notch filters based on your choice of feedback cancellation
settings.
Note:
Before you run the setup, you must select the microphones and
gating groups that will be affected.
State Shows the automatic setup status. Off if automatic setup has not been
run. Running if the automatic setup is underway. Complete if the
automatic setup has been run and is complete.
Number of Fixed Filters Up to 16 Fixed Filters are applied. If the specified number of filters are
not required, they become Dynamic Filters.
Target Gain Before
Feedback
Set your desired dB rating. The unit slowly increases dB,adding notch
filters at detected feedback frequencies until it either reaches the target
level or reaches the number of Fixed Filters (see Number of Fixed
Filters above). The system detects feedback through an open mic while
levels are increased. If the target is reached without using the specified
number of fixed filters, the remaining “slots” are used as Dynamic
Filters to be applied as the environment changes.
Affected Microphones Specify the microphone channels to which FBE will be applied.
Note:
You must make this selection prior to running the setup by
clicking Run Setup.
Affected Gating Groups Select the gating groups to which FBE will be applied.
