20 MY4-AEC Owner’s Manual

3 Adjust the DME Designer AEC component editor parameters so that

acoustic echo is effectively cancelled from the audio signal sent to Office

Begin by checking that the connection with Office X is working properly and that

conversation is possible. If echo can be heard with the default AEC section Effect setting

of “1”, try increasing the setting in small increments. Echo cancellation efficiency will

increase as the setting is increased, but sound quality will decrease at the same time so it

is necessary to find the best setting for conditions in the local meeting room while actually

listening to the audio signal.

Other parameters can usually be left at their default settings. Refer to the DME Designer

owner’s manual for details on the individual AEC component parameters.
