3.6.1.
Audio echo in reference to a voice conference system is usually directly related
to the echo cancellation software and its ability to adjust for different latencies. It
can be resultant in either the system not being able to pass the audio signal fast
enough, or the room itself and the spacing of the equipment being too large and
far apart.
3.6.2.
In the case of G4 SMART IFP’s and earlier it is recommended to use analog
audio paths over digital as the digital paths are considerably electrically longer
due to internal processing.
3.6.3.
For G5 panels in a Video Conferencing solution it is recommended to use an
external speaker system due to the side firing nature of the speakers causing
additional acoustical delays.
