5.5.3Echo Control

Mic 1-3 and Audio 4

Each of the 3 microphone inputs and Audio input 4 has a separate acoustic echo canceller. One echo canceller per input provides more sophisticated control than having one common canceller for all microphones.

In addition to echo cancellation, the system has built-in noise reduction (NR). NR reduces constant background noise (e.g. noise from air-conditioning systems, cooling fans etc.). In addition, a high pass filter (Humfilter) reduces very low frequency noise.

 

On

 

Echo control is normally set to On to prevent the far end from hearing their own

 

 

 

 

audio. Once selected, echo cancellation is active at all times. The echo canceller

 

 

 

 

continuously adjusts itself to the audio characteristics of the room and

 

 

 

 

compensates for any changes it detects in the audio environment. If the changes in

 

 

 

 

the audio conditions are very significant the echo canceller may take a second or

 

 

 

 

two to re-adjust.

 

 

 

 

 

 

 

 

 

 

 

 

Off

 

You can choose to switch off the echo canceller for the available audio sources.

 

 

 

 

Echo Control should be switched Off if external echo cancellation or playback

 

 

 

 

equipment is used.

 

 

 

 

 

 

 

 

 

 

 

 

On+NR

 

Activates both Echo Control and Noise Reduction.

 

 

 

 

 

 

Note that it is your echo canceller that improves the audio quality experienced by the other site. When you hear an echo of your own audio it is most likely the far end’s echo canceller that is malfunctioning.

Tips for improving the echo canceller performance:

ƒPlace all microphones as far as possible from the loudspeakers. Minimum loudspeaker- microphone distance should be 2 meters (6.5 ft).

ƒIt is recommended to place the microphones between 1 and 2 meters away from the persons speaking. By using several microphones, the ratio distance loudspeaker-to- mic/mic-to-speaker can be increased. Increasing this ratio improves the echo canceller performance.

ƒPlace the microphones as far as possible from noise sources.

ƒReduce the volume setting. Ensure that the loudspeakers do not distort the audio.

ƒThe echo canceller tries to estimate the echo path from the speaker system to the microphones. Moving objects change this path; therefore try to avoid moving objects. Be especially aware of large objects and objects placed close to either the microphone or the speaker system as these objects will cause severe changes to the echo path.

ƒAvoid putting paper sheets etc. on the microphone.

ƒAvoid moving the microphone or loudspeaker.

ƒIn the presence of low frequency noise, enable the noise reduction (NR).
