    Sound card scenario


    My existing audio output jacks on the motherboard look like this:


    I use the:

    Green – Front Right and Front Left
    Orange – Centre and Subwoofer
    Black – Rear Right and Rear Left


    I got the Logitech z-906 5.1 surround sound and the back looks like this:







    It’s using the three 3.5mm audio jacks that come out the motherboard and go into the corresponding coloured inputs.

    The sound card (ASUS STXII 7.1 )that I wanna get has these outputs except as RCA outputs ( it consists of two cards, one main card and a daughterboard)










    If I get three of these 3.5 mm to RCA connectors, and plug them into the outputs of the sound card and into the inputs of the z906 will it convert the sound properly, in terms of left and right and specifically centre and subwoofer?










    Hope this illustrates what i would like to do in order to achieve surround sound from the sound card.


    Any thoughts would be greatly appreciated.

    That Asus sound card is 7.1 channel, which is 8 discreet channels. The red and white outputs on the motherboard of the Asus are only for front left and right, they only have one channel of information each. I am not aware of an RCA jack that is able to carry more than just one channel of audio information, so your adaptors are going to have to be some kind of Y adaptors.

    Of, by the way, that sound card looks pretty nice.

    Why do you go for analogue connections? In the year 2015 I personally would not go for anything else than an optical digital output, connected to the amp. That's also the reason why I am sticking to Creative cards. It's not understandable to me why Asus refuses to include an optical digital output. It's the only connection that truly eliminates any sort of distortion.

    I believe that both analog and digital audio cables have their positives and negatives. In the world of high end audio, all most all of the cables are analog because of the bandwidth of analog cables, that an optical cable doesn't even come close to, not by a country mile. But an optical cable does win when it comes to RF interference suppression. It is six of one or half a dozen of the other. And don't get me started on HDMI.

    If I use the optical out ,wouldn't the z906 do the processing of the sound?

    No, it only has a DAC (Digital to Analog Converter), your computer still processes the sound but signal going ti it is digital which DAC turns back into analog to drive speaker thru it's amplifier.

    CountMike, are you sure about that? The only reason I never answered his question is because on some of my digital devices, his premise is absolutely correct. When using any digital cable out of my Blu Ray player, the processing is done by the pre/pro, but when sending analog out of my Blu Ray player the processing is done by my machine. So at this point, without all of his instruction manuals, I would be hesitant to answer either way.
