One show with multilingual output in different audio channels

Does anybody have an idea how to realize a press conference broadcast (RTMP) with two audio channels? My first idea was having input language 1 in one channel, language 2 in the second one. Is there any way to use one channel for one RTMP stream and the other one for another RTMP stream? As far as I understand right now muting a channel is just possible with the “Audio Monitor”…

Thank you for every helpful hint!

I’ve done this by using two mimoLive documents concurrently. Same video source but each document has a different audio source and different streaming destination.
