The wiring of patchbay is designed so as to group together in a logical manner, by the type and use, all wiring connected, so that it is easy to test them, monitor them or interconnect, with a greater flexibility of use with respect to a fixed installation. Disconnecting electric utilities, for connections to a plant's theatrical stage lights (DIN Rail Fiber Optic Patch Panel).
While in functionally similar cross rails or switching networks, the sources and destinations are created as a matrix and thus arbitrarily can be switched together (n: m), can be associated with patchbays normally only ever a source to a destination (1: 1). The rear is not accessible usually in normal operating on the plug-fields vary - depending on the desired signal quality and ease of remapping are (single or multi-core) connectors, spring terminals or solder tags used.
In early days of telephony conversations were manually made by telephone operators by the interlocutors were connected via plug cable. The operators were able to connect with headsets set directly on the patchbay to terminals. The audio and video patchbays enable the flexible cabling of signal outputs and inputs, for example, the outputs of a mixer to a recording device or the insertion of effects units. Moreover, it is possible to intercept signals at various points in order to identify about sources of error.
This type patchbays is also used for digital audio interface with AES / EBU, in variant AES3id; the connector used on back of a patchbay is the BNC type, while the strings have a special coaxial connector. Analog audio signals on a balanced pair or digital AES / EBU. In this case, terminals of disconnector are usually to be welded directly; the strings are stereo jack or fittings multipolar different depending on manufacturer.
Serial connections for control interfaces, with solder terminals and cords that often use multi-core cables with RJ45 connectors. Various types of parallel connections for general purposes. Connections are often solder or insulation, and the strings multipolar. The patchbay more sophisticated have a modular structure: on each panel are mounted on rear side of modules that receive two cable sections and on FRONT have two overlapping holes corresponding to two sections.
The modular structure allows to compose patchbay capable of routing connections of different types of signals on same panel, saving space if the number of signals is limited. Typically, in a panel on top rack unit can accommodate 24/26 modules. You can make a panel with, for example, video connections 8, 10 and 6 serial audio.
Naturally it is not possible to cross between them two types of different signals. As a general rule, although it is not a fixed rule, the top line of panel receives incoming connections to patchbay (and then the outputs of machines), while the lower sends outgoing connections (and therefore to inputs machines ).
There is a firm connection between all bushings, which is not interrupted by cable plugging. This makes it possible to derive from the stereo sum of mixer, the signals for a recording device. With an open configuration exists between the two jacks on no electrical contact. The patchbay or disconnector is a system that interfaces between them different sections of a wiring. Typically consists of a series of perforated panels on the back of which are radiused sections wiring. Between a hole and the other, that is, by two sections, it is possible to realize a connection via a length of cable, also called a patch cord or rope.
