Routing Switcher Basics
Signal Levels
A "signal level" represents one of many specific types of audio or video elements that a routing
switcher is capable of handling. The typical signals capable of being switched are:
•
Analog Video
•
Analog Audio (stereo with left and right channels).
•
Digital Video
•
Digital Audio (dual channel – stereo pair)
•
High Definition Video.
Some systems may be configured with one signal level, while others may be configured with
multiple signal levels.
While the diagram in the previous section shows only one signal level, a multi-signal level sys-
tem is capable of routing any combination up to 32 levels – each with its own matrix and cross-
points.
The figure below illustrates
eight signal levels
in a 10 X 10 matrix system.
Signal routers are typically much larger than a 10 X 10 matrix, depending on user needs.
Each signal level may also have different sizes of matrices and do not all need to be the same
size.
