Hi Jarad,

I don’t know your background so I hope this helps to explain the bussing concept.

if you think circuitry, then imagine there are 32 wires connecting each IP channel to the master section. Those 32 lines can be set up to go to Aux outputs, FX channels, or Sub-groups. Matrices are special and I will return to them. Interestingly, as FX channels come back from the FX into dedicated FX channels, the second half of the wires you use to feed the FX can be used for Matrices as a matrix ‘wire’ starts at the master section. The other Busses go all the way from IP to output so can’t be split.

The easiest way to get used to this is to play with the editor offline and see what happens to the total buss tally when you change the various allocations.

As to how you can use them, its not that hard if you have multiple foldback wedges, multiple IEM packs, FX, Matrices for multiple speaker outputs, including cry room, OB mix, feed to the production talkback system Sub-group for vocals…

Its only in the last few months that we have been able to remove physical foldback as the IEM becomes normal that we are starting to reclaim busses (we can have 6 bus FX instead of 4 now :)).

I hope this helps.
