Different ringing tones may be selected. You may also select different volume levels for the ringing tone.
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.
ECHO CANCELLING: 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.
