Audio Subsystem
The onboard audio subsystem consists of the following components:
•
Intel X79 Express Chipset
•
RealTek ALC892 codec
The subsystem has the following headers and connectors:
•
Five back panel analog audio connectors
•
Back panel S/PDIF output port (optical)
•
Onboard S/PDIF output header
•
High Definition (HD) Audio front panel header that provides mic in and line out
signals for front panel audio connectors
The audio subsystem supports the following features:
•
Advanced jack sense for the back panel analog audio jacks that enables the audio
codec to recognize the device that is connected to an audio port.
The back panel
audio jacks are capable of retasking according to the user’s definition, or can be
automatically switched depending on the recognized device type.
•
A signal-to-noise (S/N) ratio of 95 dB.
•
Independent multi-streaming 8-channel (7.1) audio (using the back panel audio
connectors) and 2-channel audio (using the Intel High Definition Audio front panel
header).
Go to the following pages for more information about:
•
The location of the onboard audio headers, Figure 22 on page 49
•
The signal names for the Intel High Definition Audio front panel header, page 50
•
The back panel audio connectors, Figure 23 on page 54
LAN Subsystem
The board’s dual Gigabit (10/100/1000 Mb/s) LAN subsystem includes:
•
Intel X79 Express Chipset
•
Intel 82579L Gigabit Ethernet LAN Controller (Primary)
•
Intel 82574L Gigabit Ethernet LAN Controller (Secondary)
•
Two RJ-45 LAN connectors with integrated status LEDs
The subsystem features:
•
CSMA/CD protocol engine
•
LAN connect interface between the Intel PCH and the LAN controllers
•
PCI bus power management
•
ACPI technology support
•
LAN wake capabilities (only the Intel 82579L Gigabit Ethernet LAN Controller
supports the Preboot Execution Environment (PXE) specification)
