■ “Near-end Voice” screen
In this screen you can make settings for the FBS (Feed Back Suppressor) that is built into the MY4-AEC.
① FBS[ON] button
This turns the feedback suppressor function on/off.
The FBS of the MY4-AEC uses the dynamic method of finding the constantly changing feedback points and
updating the filter settings accordingly.
This is reset when the MTX5-D is powered-off, and will return to a state in which no notch filter is inserted.
② [Width] list box
Here you can specify the rejection width of the notch filter that is inserted at the frequency where feedback is
detected. Choose a narrower rejection width if the feedback suppressor causes unwanted changes in the
character of the sound. A setting of “1/93” is the narrowest setting for the notch filter. However in this case, the
feedback suppressor may be less effective.
③ [Depth] list box
Here you can specify the amount of rejection applied by the notch filter that is inserted at the frequency where
feedback is detected. A setting of “–18” produces the strongest suppression of feedback. However in this case,
you may notice more change in the character of the sound.
④ [Near-end Voice] channel select button
This button selects the output destination for the audio signal that is output locally (Near-end Voice). Click the
button to open the “Output Patch” dialog box.
