ASUS Releases First Ever PCI-E Interface Audio Card Xonar D2X and Smallest USB Interface Audio Device Xonar U1

Hot on the heels on the success of the Xonar D2 audio card, ASUS, worldwide leader in motherboard and graphics cards, now offers users even more audio choices by introducing the first PCI-E interface audio card Xonar D2X; and the stylish USB interface audio device Xonar U1. Providing solutions for the gaming audio issue found in Windows Vista by utilizing DS3D GX, and Acoustic Echo Cancellation (AEC) for best voice communication quality, the Xonar D2X will undoubtedly provide the best gaming experience ever. The Xonar U1 on the other hand will feature eye-catching industrial design, a convenient user interface and total compatibility with both PCs and notebooks.

ASUS Xonar D2X -Solution to Windows Vista Gaming Audio Problems
With the introduction of Windows Vista, the whole audio architecture landscaped has been changed. This has resulted in teething problems for gamers – with the possibility of losing all surround sound or hardware accelerated Direct3D and EAX while gaming in the Windows Vista environment. To circumvent this problem, the ASUS Xonar family of audio cards utilizes an ASUS exclusive technology – the new DS3D GX extension in the Xonar D2X driver; to provide full support for surround sound and hardware accelerated features by translating DirectX to the DS3D GX. While other solutions like OpenAL requires special installation and game support, DS3D GX doesn’t. Gamers can enjoy DirectX gaming with hardware enhanced surround sound and EAX effects automatically and immediately after installation.

Cleanest Voice in Online or LAN Game Chatting
The Xonar D2X also includes the innovative “Acoustics Echo Cancellation” (AEC) technology to facilitate the best online voice communication quality. AEC can eliminate up-to-40dB speaker echo return and suppress noises that would otherwise enter the users’ microphone – making the Xonar D2X the best audio card choice for online chatting in VOIP applications (Skype, MSN, Google, QQ, etc.) or online gaming.

Unparalleled Sound Clarity
The ASUS Xonar D2X also features a signal- to-noise ratio (SNR) of 118 dB for both audio in and out – reaching the maximum limit of audio quality on most PC platforms. Unlike generic audio cards in the market that provide the highest SNR to only the front stereo outputs, the Xonar D2X is able to deliver 118 dB quality audio for all 7.1 channels.

Dolby and DTS for Complete Digital Home Experience
Besides delivering impressive audio quality, the Xonar D2X is also packed with multiple sound technologies from Dolby and DTS to deliver outstanding entertainment experiences. These include Dolby Digital Live, which converts PC or game audio content into Dolby Digital in real-time; Dolby Headphone, which creates a surround sound listening experience when using any set of headphones; Dolby Virtual Speaker, which delivers a vibrant surround sound listening experience from stereo speakers and Dolby Pro Logic® IIx, which creates up to 7.1-channel surround sounds from stereo or 5.1 sources as well as DTS Interactive for real time AC-3 encoding and DTS NEP: PC stereo to multi-channel expander. “As users increasingly use their PCs to enjoy music, movies, and gaming, great audio is key to delivering an outstanding entertainment experience,” said Greg Rodehau, PC Market Segment Director, Dolby Laboratories. “The ASUS Xonar D2X audio card delivers a powerful suite of Dolby technologies that create highly immersive listening environments from virtually any content or playback device being used.”

Backup Digital Music Files and Enjoy Them On-the-Go
The Xonar D2X also comes with a special application called “Portable Media Processor”. This application works with the onboard ALT (Analog Loopback Transformation) circuit to provide almost lossless analog recording audio quality from digital music files.

ASUS Xonar U1- Stylish External Audio Processor with EAX Support
The Xonar U1 is an external USB audio device that improves the laptop or PC’s underachieving audio by first eliminating electromagnetic interference (EMI) and noisy DC circuits inside the PC chassis. It then utilizes the high quality DAC (digital to analog convertor) to bring about crisp, clear music or gaming audio in the original flavor that was meant to be heard. The Xonar U1 provides a huge boost to PC gamers by supporting EAX and DirectSound HW acceleration for best gaming experience in Windows VISTA and XP.

High Quality Headphone Amplifier for Audio Listening Pleasure
The Xonar U1 brings further enjoyment to the user by utilizing the high quality internal DAC for playback of original details of MP3s; and superb output with the built-in high-fidelity headphone amplifier to achieve best listening quality with most stereo headphones (8~150 ohms @ >10mWx2).

* THD+N< 0.005% @ 47mW x2 / 32ohms
* THD+N< 0.006% @ 88mW x2/ 16ohms
* 96dB SNR * >1.1Vrms full-scale output voltage for >8 ohms load
* Frequency Response (-3dB/48KHz): 20~20KHz for 32ohms

Precise 3D positioning Technologies from Dolby Studio
The Xonar U1 also comes with a complete set of technologies from Dolby Studio to provide users with the best audio experience possible.

Background noise cancelling by advanced Array Mic Technology
With the advanced noise cancelling algorithm, along with the bundled exclusive Array Microphone, the Xonar U1 can suppress ambient noises up to 20 dB – leaving only clear voice for VOIP applications (Skype, MSN, Google, QQ, etc.) or online gaming.

SPDIF output with Dolby Digital encoding easily turns NB/PC into HTPC
Easily turn Notebooks or PCs into a HTPC by enabling 5.1 channel output via the Xonar U1's SPDIF output with Dolby Digital encoding. Just connect the NB/PC with Xonar U1 to a home theater system and start enjoying PC game or movies with original 5.1 channel audio or expanded stereo audio by Dolby Prologic IIx from home theater speakers.

I've heard many complaints from friends trying to install Logitech web cams. They get a message when starting the camera saying that the camera is not present or the camera is already in use. I suspect some sort of corrupted installation. Could this approach also work on those systems (running Windows XP)?

Hey guys,

I did these steps:
1) Plug cam into the PC
2) did the steps with Universal Extractor for x86_xp and x64_xp drivers
3) After the detection of the cam, tried refresh the driver over the device manager with the extracted x86_xp. But he means, that in the folder werent the right drivers. So I did the refresh with x64_xp drivers.
4) After that reboot and testing with Skype. Works great! After this try with Windows Live Messenger, and the messenger hung :(
5) Back with a ghost-image to step 1
6) Tried the same steps, but after the driver-refresh with the x64_xp drivers installation of the Logitech software
7) After a reboot test with Skype, and it works fine.
8) After that test with Windows Live Messenger. Result in a hang of the Messenger software :(

At the moment runs the cam with microsoft-drivers. Sound works ok, but da video is very crappy :(

I dont know what to do, any tips for me?

FragTek, thanks to you I now have a working webcam. A friend gave it to me because she had no use for it, but Logitech had no instructions on how to make it work on Windows Server 2003.

You made it look rather easy, although it would have taken me days of fooling around to figure that out.

step 6 i saw *8* subdirectories. following the instructions above failed, but when i copied the contents of ALL the subdirectories it worked. my mileage DID vary! LoL

also, the links to the screen images in the steps are all broken.
