A “behind-the-panel” connection which exists in a patch bay or panel (particularly the panel of a modular or semi-modular synthsizer).A normalled connection provides a default signal routing between an output and an associated input which is made automatically when no patch cord is plugged into the either the input or the output. Patch bay manufacturers and users distinguish between a "full normalled" connection, which is interrupted by plugging a patch cord into either the input or output, and a “half-normalled” connection which is interrupted only when a cord is plugged into the input; plugging a cord into the output effective creates a “Y” output to both the patch cord and the normalled input. (Usage on this is sometimes sloppy; “normalled” is often used to refer to either type.)
