To Stream Presentation to Remote Participants
A voice lift system that can deliver presentations to remote locations requires more advanced
design and adjustment techniques but with some limitations. The following are the elements
that need to be considered.
• Use the RM-CG's internal AEC that is optimized for the RM-CG.
• Since RM-CG's Dante CH1 outputs audio with AEC processed, route audio from Dante
Output CH1 to remote locations.
• Return only the reference signal of the far-end signal to AEC.
(Make sure not to include signals amplified by the voice lift system.)
• The sound quality of far-end
*1
and near-end
*2
will decrease because AEC’s echo
cancellation performance will drop by the diffraction of amplified near-end/far-end audio
from the ceiling speakers to the RM-CG.
*1
Near-end voice amplified by the voice lift system will again be picked up by the RM-
CG. This loop will decrease the sound quality, and the degraded sound will be
delivered to the far end.
*2:
Far-end voice amplified at the near end will again be picked up by the RM-CG. This
loop will decrease the sound quality, and the degraded sound will be amplified at the
near end.
