    Email I recieved from Creative about SPDIF

    I sent an email to Creative last night regaurding the digital SPDIF output on the regular ZS sound card and how it could be converted to an coaxial plug. Well before I even recieved the email I found exactly what I needed here http://www.ramelectronics.net/html/RCA-mini-spdif.html and bought it.

    I got the email back this morning from creative and it had a lot of information in it that I was unaware of. Here is the main part of the email that had me confused I should say.

    "CONNECT THE DIGITAL OUT TO A RECEIVER
    1. Use a stereo minijack (1/8 inch) to RCA cable.
    2. Connect the minijack end into the digital out on the sound card
    (This is the furthest port away from the firewire SB1394 connector).
    3. Connect the left (white) RCA connector to the SPDIF coaxial input on
    your receiver.
    4. Leave the right (red) RCA connector disconnected.

    SET THE AUDIGY2 TO USE DIGITAL OUTPUT
    1. Go to Start > Programs > Creative > SB Audigy 2 > Surround Mixer
    2. Click on the (+) above the main volume control.
    3. Make sure there is a check next to "Use Digital Output Only"
    4. Please also verify this under start > run > SNDVOL32 > advanced

    DISABLE AC3 DECODING
    1. Go to Start > Programs > Sound Blaster Audigy 2 > Audigy HQ > Device
    Controls > Decoder
    2. Select "SPDIF Passthru (Dolby Digital / DTS Digital Out)"

    The soundcard will now pass the AC3 signal and raw PCM data to your
    receiver to be decoded as 5.1 channel audio.

    Please note that only AC3 audio (such as audio from DVD movies) will be
    in surround sound. All other audio will be processed by the receiver as
    PCM, and thus you will only hear the two front channels. This is due to
    the limitation of the S/PDIF connection allowing only 2 channels to
    cross over a single wire. More information about this can be found at http://www.dolby.com.

    Note: There are audio options within the DVD software that need to be
    configured for Dolby Digital pass-through. These options are different
    depending on what software you have. If you need clarification on what
    needs to be enabled or checked, then reply with all the options
    available under Audio properties within your DVD software.
    "

    Let me know your thoughts and if there is anyway around this.

    What part is confusing you? What's confusing me is:
    3. Connect the left (white) RCA connector to the SPDIF coaxial input on
    your receiver.
    4. Leave the right (red) RCA connector disconnected.

    I thought that digital coax cables only had one pair. This implies that you can use regular RCA cables.

    that's one thing that caught my eye too, but I thought I just wasn't reading it right or just didn't get it.....

    digital coax is just a single RCA end isn't it?

    Yeah it is but from what I heave read it a digital coax and standard coax are the same thing. The only difference is the impedance level on the cable its self. The digital coax has a 75ohm impedance and the standard coax is 50ohm.

    Here is a site I found discussing that. http://forum.ecoustics.com/bbs/messages/5/1370.html

    What I am confused about is the fact that by playing regular MP3s through the computer into my headunit I will only recieve 2 channel sound, and doesnt that mean that only my front channel will work and I will not have a sub or anything like that? Or did I missunderstand that. Because I am under the impression that my 1 channel is front driver and 2 channel is front passenger.

    That's what I thought. I'll have to mess around with that some more. I had purchased a digital coax cable, but after trying tons of different settings, I couldn't get my receiver to play any music from the digital input. Hopefully, I still have that cable around.

    I think you misunderstood.

    Your headunit should have a digital input. If this is not the case, then you won't be able to use the SPDIF-out on that soundcard.

    Well, I think what you are confused about is ideally you want to use this cable just like M5AM said. Creative tells him in the e-mail reply to use a stereo cable. It would be just like this but with two contacts on the mini side and two RCA connectors on the other side. One of those two sides (the red they say) is basically useless when you use a stereo cable.

    LOL

    The answer to my question is that the difference is in the impedance between analog and digital cables.

    The answer to his question is not so clear, because he hasn't said what make and model HU he has in his car.
