Protocol Selection
The protocol selection within the DSpark may be changed with DCen only, see manual DIGIMIC wired.
There are five different radio protocols (performance levels) available.
The default value is 1+ standard latency.
When you change the radio protocol during conference session all units will be reinitialized this leads to a
short pause of a few seconds without audio transmission. After all units confirmed the new protocol the
conference may be continued.
#1 1+ standard latency
#2
1+ low latency
#3
1+ ultra low latency
#4
2+ standard latency
#5 2+ low latency
DIGIMIC wireless with protocol option #1 is suitable for the most conference areas. Just in case you
discover dropouts on the audio or weak connections, because of a very strong radio emitter nearby,
you can adapt the system accordingly. This will be possible in combination with DCen only.
