Using the Surround Zone Plugin & Template:
1. Open up Pro Tools and select the template soundfield recording 5xB format audio channels.
2. The project has 5 sets of 4 channels (w, x, y and z) which are sent via a quad bus to a quad aux channel. These auxes are then sent to the 5.1 master channel.
Each aux channel has the surround zone plugin insert to decode the B format signal to whichever output you require.
3. The first three sets of channels go from inputs A1 to A8 and the second two go on the octopre 1 to 8.
