Key functions AEC (Acoustic Echo Canceler) In meetings held between remote locations, such as teleconferencing, acoustic echoes can occur when the audio output from the speaker is picked up by a microphone. The audio from the other party is amplified by the speaker and can bounce off of the ceiling, walls or floors of the room, and, upon being picked up by the microphone, is returned to the other party along with your party’s audio.
Page 51
Key functions Turn AEC ON for the microphone to be used (for each channel). Setting AEC Click “AEC”. Select the BUS to be processed from "Input bus". From “Mode”, select “AEC”. From “AEC Reference”, select the reference signal (the signal for removing echoes).
