About Patch Bays and “Normalling” Schemes

All Hosa patch bays feature “half-normalled” configuration (except for the PHB-265, the PDR-369, and the MXL-369). Two pieces of gear that are con- nected, one to the rear-panel top and one to the rear-panel bottom jacks, in any single bay channel are automatically connected to each other. Plugging into the bottom-frontjack of that same channel breaks the connection.

This “half-normal” configuration is the perfect combination of versatility and affordability, and it easily handles all of the patching scenarios needed by most commercial and home studios.

De-Normalled operation for Hosa patch bays (straight-through wiring) is accomplished by turning around selected internal channel modules 180 degrees, except on the PHB-360 and MHB-360 which can not be de-nor- malled.

The PHB-265uses recessed, front-panel switches to select half-normalled, full- normalled or de-normalled operation, so rotating the modules isn’t necessary.

The PDR-369 and MDR-369XLR bays have no normalling (straight through only).

A “Half-Normalled” patch bay is incredibly versatile. By inserting a plug into the switching jack at the front bottom position, you can break the “normal connection” between top and bottom at the rear. Here’s a simplified example:
