the defined directional “flow” of sound throughout a studio, setup, system, rig or whatever.
Types of Patchbays
Signal Flow Break Down
XLR – 1/4″ – TT
Most signal audio production signal flows can be broken down into this basic format:
Used to interconnect any piece of equipment throughout a studio
Signal flow is routed throughout a studio via external cables or internal busing
with db25 connections on back
Analog vs. Digital Signals
De-Normal, Full-Normal, Half-Normal
Most simple patchbay configuration. Requires every piece of equipment to be patched with a patch cable.
Automatic connection between top and bottom. Allows for “normally connected” signal paths to remain connected without patching. Adding a patch cable to the top or bottom breaks the normal.
An overview of a system’s signal flow
Most common studio patchbay setup. Similar to full-normal, but the normal is not broken if a patch cable is plugged into the TOP jack. It splits the signal, keeping the normal and allowing for an additional signal path. Plugging into the BOTTOM jack breaks the normal.
