The ASUS Xonar DX is a PCI-E sound card with a 116 dB Signal-to-Noise Ratio (SNR), which provides audio that is 35 times cleaner than onboard audio. With the support of Dolby technologies and GX2.5, the Xonar DX provides rich audio effects in games and theater quality audio in movies.

Dolby is globally recognized for their innovations in audio for cinemas, home theaters, PCs, and games. With Dolby technologies, your PC is upgraded to surround sound and transformed into an immersive digital entertainment center. These include Dolby Digital Live (Real-time 5.1 Dolby Digital surround sound encoding), Dolby Pro-Logic IIx (Converts stereo or 5.1 sounds to a seamless 7.1 surround sound field), Dolby Headphone (Delivers a realistic and spacious 2-to-5.1 surround or 3D positional sound field over any set of stereo headphones), and Dolby Virtual Speaker which simulates a highly realistic 5.1 speaker surround sound listening environment from as few as 2 speakers.

ASUS designed GX2.5 to simulate EAX game effects and makes them available on Windows Vista/7 PCs. GX2.5 will automatically emulate the latest EAX technologies without additional software.

  • newegg High Signal-to-Noise Ratio (SNR) A high SNR rating means less unwanted noise. Therefore the audio is cleaner which translates to better sound quality. The Xonar DX achieves a 116 dB SNR rating for clear audio in games, movies, and music.
  • newegg Dolby Technologies A rich Dolby feature set is supported in order to enhance PC audio with surround sound. A surround sound experience can be achieved with as little as two speakers or even headphones.
  • newegg GX2.5 GX2.5 automatically emulates the latest EAX technology – up to EAX5.0, to offer advanced environmental audio effects. While enhancing the feeling of actually being in the game, GX2.5 also improves on directional audio information.
  • newegg Low Profile The Xonar DX is bundled with a low profile bracket for compatibility with HTPC cases.
  • newegg VocalFX VocalFX is an innovative voice processing technology to let your voice get into the realistic game landscape (VoiceEX) or to emulate the background scenes in online chat (ChatEX). It also allows you to change your voice pitch to disguise who you are (Magic Voice).

3 out of 5 eggsGood Product

Pros: Good not great sound.Easy install.Kudos for included power cable adapter.

Cons: As people before me have noted the drivers can be a little tricky.I first went to support site and downloaded the driver.After install the sub woofer for my- Z5300`s was not playing.Uninstalled driver and used included disc for Windows 7 64 bit and it works just fine.Need to find a front audio panel to use with my Dell Optiplex 780 MT.Not much of an upgrade from my Xonar DG.Some sound cards have inputs colored to make cable hookups easier.

Other Thoughts: Luke warm on recommending card.

2 out of 5 eggs

Pros: It works sometimes.

Cons: The program for the card is horrible. When you test the 7.1 sound the sound doesn't come out right. An example would be when i tested the right back audio it would play from the left. I would have to repeatedly keep clicking the sound test until it can out of the correct side. The sound also sometimes goes mono to stereo randomly.

Other Thoughts: Save your money for a better one.

4 out of 5 eggsGood product!

Pros: + Sounds great
+ Sound customization options

When I first listened to some music with my new sound card I felt as if I went from listening with a 2.0 speaker setup to a 5.1 speaker setup all while using a $50 Turtle Beach headset.
The card comes with software that allows the user to change several audio options easily. It's almost the exact same as using the Windows Audio manager only I find it easier to access and it comes with some simple options for users that don't want to go into an equalizer such as, +Music, +Game, +Movie, and +HiFi.

Cons: -Power connector seems a bit weak

When I first plugged in the external power source everything went in smoothly. As I continued working on my rig I needed to unplug the external power cord and it was a fight to do so. Now it has a weak connection even though nothing looks to be out of the ordinary. If the connection isn't pushed in very tightly it doesn't get the power it needs which feels like a design flaw.

Other Thoughts: Overall, I like this card. It sounds great, has several customization options/features, and looks good as well.

5 out of 5 eggsHear the Noise.

Pros: Used this card in a build for a client. He was use to Creative Sound Blaster cards which are great. Talked him into this one for a economy build. With careful tweaking and additional software he believes this card does and sound as good as the Sound Blaster line. Great experience.

Cons: None at this time.

Other Thoughts: Great price for the quality.

3 out of 5 eggs build quality is subpar but when you figure out the problem ahmen

Pros: very good sound quality when you discover what the problem is i will explain in cons
i use the aftermarket drivers and they are beautiful even on these hp stock spare speakers lol before i fixed the power cable i could'nt put my speakers past 20% volume without distortion now i cant put it to 100 due to neighbors lol

the whit power connector isnt actually soldered to the pins n the pcb so it tends to come loose to fix this just push the white adapter in requires a little force but then it just slides back and it fixes the "china grade" floppy cable problem

Other Thoughts: so overall i actually love this card but the cheapos should have put a different power adapter on it because when it is loosens not enough power is supplied and the sound gets distorted. Funny thing is the only reason i discovered this was when i was getting ready to pack it up haha the power cord tugged slightly and i noticed the white bracket wasn't at all on there right.

4 out of 5 eggsBoom

Pros: Excellent signal to noise
Excellent sound quality
Solid output selection
Software adjustability

Cons: Power plug can be finicky.
Started losing the right channel after warranty expired. I used to be able to pull the jack and plug it into another port to get the channel back. Now when I do it I either get a BSOD or the audio breaks till reboot. 4 years of use.

Other Thoughts: I use my computer to play games, listen to music (FLAC lossless only), and watch movies. My xonar outputs to a vintage 70s pioneer receiver that has been cleaned up internally. The A channel goes to a pair of floor standing three way speakers. The B channel outputs to an adjustable active line level converter to RCA. The RCA output is fed into a vintage 98 PPI powerclass 2150 amplifier which powers a single JL 12w6v2 in a sealed 1.5 cu ft enclosure. The amplifier is fed power by a 650 watt Antec PSU I recapped and modified for 12 volt output (12.2v output under load).

Why did I tell you this? Because I wanted you to know how serious I take audio. With the integrated audio my system sounds okay. The extension on the low end is pretty bad. With the xonar I get sound below 20hz with cone movement down to almost 5 HZ. On the high end I get sparkling clear sound. When listening to properly recorded symphony music I can close my eyes and it honestly feels like I'm there in the crowd. This card absolutely blows away my old soundblaster 5.1 card.

The sound card has given me no issues with compatibility. I'm not a fan of EAX and such though (sounds artificial even with a soundblaster card) but the features performed like they should.

The built in software is solid giving you a good deal of control over the card's output.

An excellent buy and if you have some extra money you might consider getting the more costly asus card for the upgradable op amps and the improved shielding. If you don't have high end equipment then this xonar will cover you fine.

5 out of 5 eggsSounds Great

Pros: High quality hardware at a fair price.
Low profile bracket works great, box had everything I needed for install.
Sound quality out of digital and analog is fantastic. Tested head phones, 2.1 desktop system and home theater.

Cons: Throw away the driver disc and never look back.

Other Thoughts: Use the after market drivers for this card and you can unleash the full potential of this card. Do a search for your card and you will see.

1 out of 5 eggsA Product That Never Worked

Pros: Looks nice.

Cons: The audio card in question could never be recognized under Windows 7. Tried to install in on a brand-new Z97 mobo from Asus (an expensive Pro version).

Other Thoughts: I connected an auxiliary power connector, tried to change the PCI-E slots, but nothing ever worked. The card drivers (tried two different versions) kept telling me to install the card.
Some people say it's an EEPROM mess-up.
I am tremendously disappointed with this product.
Thanks for nothing, Asus!

5 out of 5 eggsWorth the splurge

Pros: I bought this for a build while I was in the process of setting
my credit on fire, I still don't regret this purchase.

The price tier that this sound card is on is perfect for people who
want a nice step above motherboard audio and don't mind spending
$50 > $100. The Asus cards for $50 < are still very solid but here your paying for more shielding, a nicer DAC, more potential to fiddle with settings in windows and sound doesn't degrade with volume. Bass response is great too.

A big bonus to this particular card is, it installs perfectly in Linux. This is a good thing because another Asus card or two have deal breaking bugs in the Alsa driver such as no front panel audio : /

This card has a great front panel audio sound through some decent headphones. Watch the size of your cans though, Ill cover this below.

In addition to music and games, movies sound great too. This card would be a great choice for a HTPC if you have a solid amp to feed(to maintain a good sound path) or of its not so great, you can avoid fuzz. There is no optical!!!!!

Cons: There aren't many cons with this audio card except for a few sort ofs:

Keep in mind, this card does not have digital optical!!! Don't buy it without reading and trash/complain about this card here because you weren't paying attention!

This card will have trouble driving very powerful headphones, the
amp definitely could use a bit more oomph. Make sure you have a nice headphone amp if you have really big cans. Generally though, folks spending that kind of money on headphones would be getting a proper amp as well. Low and Mid powered cans work just fine.

Some of the sound shaping,virtual dolby for headphones tweaks etc don't really sound that great but those kind of tweaks never really do. Just stick with traditional levels and leave the other stuff alone.

I see that people are having some trouble with installation in Windows 10 which, yeah, that is definitely annoying if you just bought the card and your running 10.
With that said,its just due to driver support and the fix will assuredly come. You could be stuck with a card in Linux where its toss up wether the bug will get fixed.

Other Thoughts: Great card. Could use a slightly better headphone amp but that's
my only gripe. Spending another $50-$75 would net you that
but spending more if your not editing or producing would be kind of silly.
