BUILDING YOUR SYSTEM WITH MULTIPLE VOR-

Operating as One Automixer with Multiple Vortexes

Example: Room Combining

To set the Vortex to operate as one automixer across several Vortexes, set the BUS MIXER parameter on all Vortexes to the same automixer group.

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 BUS MIXER option should have the fol- lowing settings:

The various room setups can be saved in the user defined presets or can be changed with macros.
