The ADH connector is an interface that allows high-definition audio devices to connect to motherboards manufactured by Asus and other companies. The acronym stands for Azalia Digital Header.
Origin
The ADH connector uses Intel Corp.'s high definition audio specification. This specification defines the physical characteristics of the interface as well as the way codecs -- devices that code and decode data streams -- work with the interface.
Identification
The ADH connector is a socket containing 16 pins. It is usually black and located along one of the motherboard's outer edges. In cases where it does not run a cable to a port on the computer's back panel, it can be accessed only by opening the computer chassis.
Compatibility
The connector is an alternative to the widely used AC'97 interface. Though the two are both HD audio connectors, Intel designed "Azalia" as a completely separate interface. As such, it is not compatible with AC'97 devices.
