Audio - HP Compaq d530 MT Supplementary Manual

new key technologies and features of HP Compaq Business Desktop d530 series

Audio

Ability to use smaller and narrower cables (From 2" w to 1/2"w)
Use of a low voltage interface for improved noise immunity
Improved air flow and cable routing in systems due to smaller cables
SATA is a point-to-point device. This means there is only one dedicated controller
per device (under Win2k or WinXP). The entire bandwidth for the interface is
dedicated to only one device.
SATA has increased reliability vs. PATA. Fewer pins and signal wires are required
for SATA, enabling more reliable connections on the board and storage device.
Also, SATA applies Cyclical Redundancy Checking (CRC) to the data and
command packets (for detecting errors that may occur during data transfer)
compared to PATA which applies CRC to the data only.
Although the 865G chipset does support SATA, HP engineering does not believe the
entire solution is ready for mainstream corporate deployment. Essentially, the current
maturity of the SATA subsystem (controller/driver/HDD) does not meet HP's robustness
and error recovery requirements and hence will not be made available until after the
d530 launch.
The HP d530 series products will be "SATA ready" at launch. A customer can
purchase a third party SATA HDD and cable and expect some functionality. This
allows customers to begin cursorary SATA testing.
The HP d530 series platforms feature a number of new audio enhancements. The Intel
865G chipset includes integrated audio support, but HP has chosen to also
incorporate the following features:
Integrated Digital Audio
with S/PDIF (Sony/Philips
Digital Interface)
Stereo Microphone Jack
Integrated Digital Noise
Canceling
Pureaudio
MAX
SOUND
All digital: allows the transfer of digital
audio signals from one device to another
without having to be converted first to an
analog format.
Improved quality: maintaining the digital
signal prevents the quality from degrading
when it is converted to analog
Enhances audio support for VoIP (voice over
internet protocol) and speech recognition.
Supports array microphones.
Located on the rear I/O panel on the CMT
and SFFchassis, and the front I/O panel on
the USDT chassis
Algorithm that delivers a pure audio signal
and removes unwanted noise in voice-input
and microphone
Continuous and repetitive noise is removed
from the audio input
Less digital distortion when used with speech-
enabled applications
