Combining
Let’s take a room combining setup as an example. You have 3 rooms, each with 8
microphones, therefore needing 3 Vortexes. For the purposes of this example, the 3
rooms can operate as 3 separate rooms, 2 rooms with 12 mics each, or one large room.
When the system is split into 3 Rooms, the B

IXER
option should have the fol-
lowing settings:
When split into 2 Rooms:
And finally, all combined into one room:
The various room setups can be saved in the user defined presets or can be changed
with macros.
