ROUTING SWITCHER SYSTEM (E)
4-4. Basic Setup Procedures
Virtural and Level Mapping
Level 1
Level 2
Level 3
Example : Destinations
. Satellite 1 connected to SDI routing switcher OUT 9
(SDI routing switcher given label destinations 001-032)
. DAT 1 connected to AES/EBU routing switcher OUT 9
(AES/EBU routing switcher given label destinations 033-048)
. Satellite 1 connected to Analog Audio OUT 9
(Analog audio routing switcher given label destinations 049-064)
Therefore :
SDI Satellite 1 (Sat001) ········· virtual level 1 out label 9
AES/EBU (DAT001) ······ virtual level 1 out label 41
Analog Audio Satellite 1 (Sat003) ········· virtual level 1 out label 57
If DAT001 destination is changed on a control panel only output label 41 (AES OUT 9) changes. Good
in situations where few signals logically follow from one level to the next (DAT’s and cameras, Mics and
CG’s, Audio Mixers and Still Stores, etc.). With this approach any sources/ destinations that should
follow across multiple routing switchers would require phantoms (covered later) to implement multiple
crosspoints switched.
A combination of virtual, and level mapping combines both approaches as shown in figure 6.
