That is a lot of S/PDIF in and out capacity. The HTPC crowd should be pleased with its audio management capabilities.


The shelf-presence oriented packaging is standard fair for Asian market hardware. Product shot, flames and a cloaked stranger adorn the front which includes the obligatory feature icons. The Dolby Digital Live logo is prominent feature, visible on front, top and back panels. The phrase "Dolby Digital Live" is visible on all but the blank bottom of the box. I get the feeling they are trying to tell us something.

Box and Contents

My review unit still had the original Korean packaging and text on the back though BlueGears should have new box text ready for US consumption when you read this review.

Original Packaging

The card comes neatly wrapped in a static bag with a driver disk, manual, DVD/CD digital cable and optical S/PDIF cable all tucked neatly underneath. I started perusing the manual with low expectations only to be pleasantly surprised by the usefulness of the content. The installation process even displayed the points at which you cancel out of the Windows auto install process and run the set up utility.

I can't take it anymore; I've got to see the card. There is something about the smell of new hardware I absolutely love, fresh like a silicon Spring day. The PCB is black with gold text, PCI bracket and connections. There are small capacitors surrounding the channel conversion chips with green caps that give the card a busy, yet purposeful look. The back end of the card includes connections for the digital CD/DVD drive input, two standard audio drive cable inputs, and the MIDI and S/PDIF expansion board ports, both available as optional components. Outward, you have the six 1/8" stereo mini-jacks for the multi-channel output and microphone and line inputs. Most important, you have the coax and optical S/PDIF outputs, the latter with a protective dust cap installed as shipped.

X-Mystique 7.1 Gold


Following the instructions from the manual, something rarely done in this household, I shut down the PC, installed the card and disabled the on-board audio in the BIOS. The first mark against the Mystique pops up here; the card leaves my front microphone and headphone ports stranded. There is no analog front I/O connector. Press the power button after a moment of disappointment and upon restart, I was greeted by the manual predicted "Add New Hardware Wizard" which I promptly cancelled out in favor of running the set up from the driver disk. A quick restart and we are back Dolby Digital Encoded in business.

I started by familiarizing myself with the audio rack. The Xear3D control panel icon shows up in the system tray with six selectable options; Open, Volume Control, Windows Media Player, Sound Recorder, Multimedia Properties, and Exit. Most tray buttons do not include quick access to Windows system features; this is a welcome change for an Audio driver task tray applet.

Selecting Open brings up the Xear3D Control Panel. It is an intuitive interface that allows you to adjust the outputs, listening position, and speaker position and levels.

Speaker Configuration Options

A quick note here - when in Dolby Digital Live mode, the analog ouputs are disabled. This may give insight into how the system work, as it would seem reasonable that the analog signals are rerouted from the discrete channel outputs into the hardware encoder. This is the basis for one of the complaints audio purists have with DDL. You have to add another analog to digital conversion, there by inducing some compression loss. The only time this compression loss has an opportunity to be noticed is in situations where each of the six channels is running at higher output levels. Is it an actual complaint for most users, no, and moreover the instances where the encoding "loss" could happen when gaming will be moments too frenzied for the gamer to perceive the inaccuracy.

More Control Panel Options

Four additional tabs include and audio mixer, effects, karaoke settings and driver information panels. The mixer is an extension of the Windows sound mixer with a snazzy interface. The effects tab includes the ten channel equalizer which utilizes, roughly, the same ten frequencies as the Windows Media Player. The Equalizer sports twelve presets. There are four Environment buttons; Bathroom, Concert Hall, Underwater and Music Pub. They lend unique echo and distortions to the audio information sent to the sound card. Available in a drop down menu are twenty-two more environmental options. Try Doom3 on Psychotic. Funny stuff. It is like a permanent case of the zombie ripping rage.

I continue the stroll through driver applet bliss with the little used Karaoke tab. My brother-in-law lived for many years in Tokyo and the fascination with Karaoke in other countries is not appreciated in the United States. There is echo reduction, key shifting and voice cancellation sliders for tweaking your Karaoke rig to full "Love Me Tender" bliss. Sorry, I did not actually test this portion of the sound card's capabilities as my neighbors are nice people, but I do not want to test their patience just for the sake of testing their patience.

Finally, you have the information tab where you can view driver revision number, DirectX version and more. You can also select to disable the Xear 3D audio properties icon.

Utilities and Demos

Also included on the disc is a Media Rack, an audio file and CD player and a few 3D positional audio demos. Play3D has an assortment of motion, sound types and environment to give your friends a quick demo of the surround capabilities. Rockwar is a rudimentary game with simple 3D audio effect and Helicopter is an advanced version of the chopper demo used in Play3D and in the audio tuning controls.
