Audio Subsystem
The onboard audio subsystem consists of the following:
Realtek ALC889 audio codec
Back panel audio connectors
Component-side audio headers/connectors:
Intel® High Definition Audio front panel header
S/PDIF connector
The audio subsystem supports the following features:
A signal-to-noise (S/N) ratio of 95 dB
Independent 7.1 audio playback from back panel connectors and stereo playback
from the Intel High Definition Audio front panel header.
Meets Microsoft Windows Vista (WLP 3.08) premium requirements.
Universal Serial Bus (USB)
The motherboard has four USB ports and a further five can be added via internal
headers; one USB peripheral can be connected to each port. For more than nine USB
devices, an external hub can be connected to either port. The motherboard fully
supports the universal host controller interface (UHCI) and uses UHCI-compatible
software drivers.
USB features include:
Self-identifying peripherals that can be plugged in while the computer is running.
Automatic mapping of function to driver and configuration.
Supports isochronous and asynchronous transfer types over the same set of wires.
Supports up to
127
physical devices.
Guaranteed bandwidth and low latencies appropriate for telephony, audio, and other
applications.
Error-handling and fault-recovery mechanisms built into the protocol.
NOTE:
Computer systems that have an unshielded cable attached to a USB port may
not meet FCC Class B requirements, even if no device or a low-speed (sub-channel)
