Asus Xonar U7 DAC/AMP Appreciation & Impressions Thread - Page 9

post #121 of 323
Then go get the Echelon. The standard U7 works, but only very basically. See my earlier post above.

Like pietcux said before, in OSX there is a problem with adjusting the gain setting of the amp (which is most likely on the lowest gain setting). The same issue is happening on Linux.

 

Instead, on Android 4.x the gain setting is stuck on the highest gain setting; I couldn't find a way to change this somehow.

post #124 of 323

Does anyone have any idea how to get a subwoofer workin in a 2.1 setup with this sound card?I have my speakers plugged into the rca ports of the card and my yamaha yst-sw012 in the ctr sub port but all i can do is to configure it to a 5.1 setup without center and back speakers.And the sound is very weird,the sub is working but the stereos are getting a 5.1 signal or something and are echoing and i cant hear any singing.Sorry about grammar im in a breaking point after whole day trying to figure this out.I took 2 days of from work to get the sub from UPS and now when i got it the problems still go on.Help.Please.

I was able to get perfect sound with the 5.1 setting on both RCA front speakers and the SUB port too. With the 7.1 setting everything was perfect too, same applies for quadro setting (subwoofer in one of the rear-out jack).

 

I was playing some regular stereo music, YouTube and movies with VLC and wmplayer.

 

So, maybe you have an environment effect applied by default? You should uncheck the Enable Environment Effects for better audition.

I have the exact same doubt:

 

Quote:
One question I had, for owners of the device, is regarding the volume control. Is the volume control 'software' based, i.e. driver-dependent, or does it occur post digital conversion in hardware? In other words, when turning the volume knob, does the volume level in Windows or in the device's driver software move, or is it an entirely analog adjustment that uses a built in amplifier? Hopefully the way I've worded this question is clear, I'd really like to know.

 

When we don't have any headphone connected and we turn the volume nob on the Xonar U7 will it decrease Windows volume or is this the volume for U7's internal amplifier? 

post #128 of 323

If you disconnect all outputs, you will see the green Windows volume bar moving on your screen. That also happens, no matter which output is used. So the U7 volume is is permanently maxed but we adjust the input signal volume from the PC. Is that bad? I do not know.

As far as I remeber all my soundcards so far did this, even the Xonar STX.

I'm having some problems with the U7 drivers. 

 

1. Whenever the Dolby Control panel is activated all stereo sound gets output to all 5.1 channels into some sort of weird surround-ish mix. The only way to get stereo music to output as true stereo (into left and right channel only) is to deactivate the dolby panel and select Hi-Fi mode from the Xonar panel.

 

Is this normal? Why does the Dolby system try to upmix all my sound (regardless of settings)?

 

2. Subwoofer sounds are not throughput to my front speaker. This is a bit of a problem as I have no subwoofer and hence miss out on all the LFE sounds. I've found no speaker configuration-settings in the Xonar or Dolby control-panel to adjust this. 

 

--------

 

My system: 5.0 system, set up with analogue cables to 5x mono-amplifier blocks. The windows sound settings are set to 5.1 with subwoofer disabled.

You can uncheck the headphone virtualisation in the active Dolby panel. You can uncheck all functions of the panel seperately. But I do not know about the subwoofer part as I only use headphones or some very basic stereo speakers from Logitec. And yes ther is no 2.1 setting in the brown Xonar panel. only 5.1 and 7.1. Maybe Asus thought that 2.1 is out somehow. And in case of the 2.1 speakers that I had, the woofer got the full stereo signal and applied the bass to itself in mono and the mids and treble to the satelites in stereo. But the basic signal was full range stereo, not 2.1.

Yes, but even with all the setting unchecked the Dolby panel still behaves like described.

 

Been testing a bit here and it definately seems like a bug. Sometimes the the sound is output in true stereo only and sometimes it is upmixed into 5.1. I have yet to pinpoint how and when this occurs. I can jump in and out of the Dolby panel without making any changes and suddenly it decides to output the sound correctly.

 

Here's one way I have found though to get the Dolby panel to behave normally every single time:

I set my system to 2.0 channels. Enter the Dolby panel and confirm that it outputs stereo only. I select music mode and disable everything. I then turn of the Dolby panel, set the system back to 5.1 and enable the Dolby panel again. The sound is now still output as stereo only. As soon as I touch any of the settings is immediately goes into upmix mode and stays that way regardless of settings.

 

Until this bug is fixed I'm ditching the Dolby panel and using using Xonar panel only.

 

(Oh and I have the latest drivers installed, btw).

Another question - what is the difference to the Echelon version of the U7 (besides the fancy army paint scheme)?

 

I notice that for the Xonar U7 the latest driver available is Version 7.0.11.17,

whereas for the U7 Echelon the lastest driver is: Version 7.0.11.19.

 

Havent tested yet, but are there any reason why the Version 7.0.11.19 shouldnt work for the regular U7?

post #133 of 323
I found the newer driver some time ago. On Windows7 64 it will not recognize my standard U7. I.e. there must be a little hardware difference.
post #134 of 323

Just got this little guy but I am still undecided on my new headphones to use with it.  Debating between the Philips Fidelio X1 and AKG Q701.  I want to lean towards the Q701's but I am concerned the U7 wont be able to drive them properly (also concerned about build quality as they are now made in China, but thats a different discussion).  Any suggestions?

post #135 of 323

Thewreck13, Xonar U7 will drive your Q701 at only about half of power, with headphone amp to max gain (0dB). For very quiet listening environments this might be a decent low cost choice.

 

If you intend to use the U7 internal headphone amplifier and want to benefit by a full power driving then you should go for the Philips Fidelio.

For full power driving and a much better listening experience for the AKG Q701 you will need to use an external amplifier connected to U7 (like Objective2 for example).

 

A thread comparing X1 and Q701 might be this one: http://www.head-fi.org/t/670318/philips-fidelio-x1-review-comparison.
