Connector pin outs
HTP Cables standard connector pin outs
This section contains the standard HTP wiring specifications used with the more common audio multipin connectors. All systems manufactured at HTP follow these wiring schedules, making maintenance and system expansion a simple procedure. The use of a standard specification also makes the practice of sub-hiring, common in the P.A. industry, an easy and trouble-free exercise. If you require any other wiring specifications please contact us.
Patch bay normalling
A patch bay is normalled when the top jack socket (output) and bottom jack socket (input) of a vertical pair are connected together, allowing the signal to pass through the patch bay, when no patch cords are inserted. There are three methods of normalling a patch bay: half normalling, single normalling and double normalling.
Half normalling
When no patch cord is inserted, the signal passes from the top jack (output) to the bottom jack (input) of a vertical pair. When a patch cord is plugged in the top jack, the signal still passes to the bottom jack, allowing a parallel for example. When a patch cord is inserted into the bottom jack, its connection from the top row is broken.
Single (Full) normalling
When no patch cord is inserted, the signal passes from the top jack (output) to the bottom jack (input) of a vertical pair. When a patch cord is inserted into either the top jack or the bottom jack, the connection is broken.
Double normalling
When no patch cord is inserted, the signal passes from the top jack (output) to the bottom jack (input) of a vertical pair. The connection can only be broken when a patch cord is inserted into the top and the bottom jacks.
