• Ducker can reduce audio deterioration mentioned above as it stops amplifying voice lift with
the trigger of audio signals from the far end. However, there is the following limitation.
 When a double-talk occurs (when both near-end and far-end speakers are speaking at
the same time), for example when a near-end speaker starts speaking while a far-end
speaker is speaking, the near-end speaker's voice will not be amplified by the voice lift
system. Therefore, we need to set a rule in which a far-end speaker should not speak
while a near-end speaker is speaking.
The following is the simplified diagram of the MRX7-D configuration.
