The N–1/Mix-minus Assignment window allows the setup and configura-
tion of the N–1/CleanFeed/Mix-minus structure.
The principle of N–1 is summing; i.e. all desired channels (N) get summed
to a bus except the "minus one" (–1).
The N–1/Mix-minus bus is a special bus that sums the contributions of
channels other than the Bus Owner of the Channel, thus performing the
N–1 summation. Any number of Mono and/or Stereo N–1 buses can be
configured in a Session Configuration.
The Bus Owner channel is the channel which:
• Does not contribute to the N–1 bus
• Contains the N–1 bus output level and Talkback controls on the
physical channel strip assigned to it
• Has an N–1 indication on the assigned channel strip.
The setup and assignment of the N–1 has a number of processes.
1 A Bus Owner (–1 channel) must be assigned to an N–1 bus.
2 The N–1 Send Line (Physical Output) and Return Line (Physical In-
put) must be patched in the General Patch
3 The channels which are to be sent to the –1 must be assigned to the
bus.
The N–1 Assignment window allows fast setup of this process.
Setup is as follows:
1 First choose the N–1 bus to be used with the drop-down menu, and the
Bus Owner Channel which will be the –1 channel.
2 Use the drop-down menus to select the Return Line (Physical Input)
and Send Line (Physical Output) to which the Outside Source (–1) is
connected to the console. This is essentially making cross-points in
the General Patch without having to go to the General Patch page.
Selections made using these drop-down menus will change any previ-
ous patching of the Outside Source. Please note that the label type
shown is taken from the General Patch.
3 The two Channel Assignment check boxes allow fast allocation of all
Input Channels to the chosen N–1 bus. If only Mono inputs are cho-
sen, then all Mono input channels in the system (except the Bus
Owner channel) are routed to the chosen bus. If specific channels
need to be routed instead of all Mono or Stereo input channels, the
