The N–1/Mix-minus Assignment window allows the setup and configuration
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 con-
figured 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 is done in three steps:
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 Input)
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 previous 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 chosen, 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 Show Channels button should be
clicked. This will extend the window as shown below, to allow individual
assigning of the channels within the Session Configuration to the chosen
N–1 bus.
