AudioIn Mode
Mic:
If a microphone is connected to AudioIn (through a microphone amplifier), select ‘
Mic
’. This will activate
echo cancelling and will prevent the far end from hearing their own audio. In addition to echo
cancellation, the system has built-in noise reduction algorithms (NR). NR reduces constant background
noise (e.g. noise from air-conditioning systems, cooling fans etc.). In addition, a highpass filter
(Humfilter) reduces very low frequency noise.
Aux:
If playback equipment is used, select ‘
Aux
’. No echo cancelling will be performed.
