Integration of additional microphones/stereo submix

Stereo master outs to   
External Inputs L & R 

Additional microphones

The Atmos 5.1 controller allows to integrate 
additional microphones as stereo or surround 
submix. During monitoring, the level settings for 
the ASM 5 determine the mix relation between 
ASM 5 and additional microphones. 

In general additional stereo mixes can be 
connected to the External Inputs. For integra-
tion of additional microphones as a stereo mix, 
an external sub mixer, connected to the External 
Inputs L&R, is needed to create the mix.
