Q:
What is Normalling? What's the difference between Full-Normal, Half-Nornal, and De-Normal?
 
A:
A Normalled patchbay has vertical pairs of jacks (usually IN and OUT) where audio automatically flows between the two jacks. Usually, patchbays rear panel connections have some option for normalling. Normalled patchbays can be FULL-Normalled, or HAlf-Normalled

Full-Normal : Rear panel connections are linked, BUT are broken when a front panel connection is made.

Half-Normal : Half-Normal bay is one in which the rear panel connections are linked, a connection made to the TOP row of the front panel does NOT break the link, but a connection to the BOTTOM row DOES break the link.

De-Normal (aka Non-Normal or "isolated") : Rear panel connections are not linked to each other. Rear panel connections are routed directly to front panel connections (eg : top rear <> top front)


See diagrams provided with your patchbay for changing normalling configurations.
