3) If echoes are still generated, turn down the speaker level of your PC or
webconference system or decrease the microphone gain of this unit.
3. Configure the feedback suppressor settings.
1) Perform the environment learning of the feedback suppressor.
i. Set the microphone gain slightly higher than the threshold level (start
of acoustic feedback generation).
ii. Acoustic feedback will be repeatedly generated and stopped. If the CLIP
LED (red) turns on continuously in the process, decrease the
microphone gain to reduce the acoustic feedback generation.
iii. If acoustic feedback generation is completely stopped, set the
microphone gain to the original level.
2) If acoustic feedback is still generated, set “Level” of “Feedback Suppressor”
to “-18dB” and then perform the procedure 1) again. However, this setting
may affect the quality of sounds output through the public-address system.
3) In addition, to control acoustic feedback immediately, set “Band width” of
“Feedback Suppressor” to “1/60oct”. For more effectiveness, set it to
“1/10oct”. However, this setting may affect the quality of sounds output
through the public-address system.
