  • USB sound card output level

    Hi, I've not found a clear information in forum. Sorry.

    I have a 3 amplifier installation : front stereo / rear stereo / sub
    My infill G4 don't have line outs to connect to the amps.

    So I plan to buy a USB 5.1 or 4.1 sound card. eg: Turtle Beach Roadie...

    The installer(pro but not for carputer) warn me about the output level of the soundcard to attack the amplifiers.
    He would like something around 2v per channel.

    As far as I understood (FAQ, ...), the SB audigy 2NX was claiming 2vrms !
    The Turtle Beach and most of the other USB sound cards says nothing

    The question is :
    - Is there something basic I did not understood?
    - Does the Turtle Beach powerfull enough.
    - Which other USB ones should I consider ?

    Thanks in advance
    Alain


    For info the current materiel is:
    1 Infill G4
    1 audison VR 404 XR (Front channel)
    1 audison LR 435 (Rear Channel)
    1 sony XM 5520 (Sub)

    Also I found the documentation of the Audison (not the Sony one)
    The VR404XR has an input sensitivity of 0,15 V 1,5 VRMS
    The LR435 0,15 V - 1,5 V
    The Sony I don't know

    I would go with the SB audigy 2NX. It has 2v rms signal. I use the audigy 2nx for my setup. I have the sound card 2 ft away from my carputer which is mounted in the trunk area. Your systems is in the front of the car, which your going to have to run rca back to the amp.It would help if maybe if you got voltage booster to get the volt to at least 4-5volts since it further distance from front to back. If it was mounted in the trunk, can go from carputer right into the amps, less distance to travel for signal loss.It will still sound good w/ just the 2v to the back, but you would get a little better sound with card+ boosters.

      Hi
      Thanks for the info. I was thinking the same initially.
      The Audigy 2NX was looking very good, unfortunately this product is not available anymore and I did not find any who sell it.

      Do you have more informations about the booster.
      Also did any one has idea about a :
      sound card => signal booster => my amps
      in comparison with
      Infill internal amp => High level to low converter => my amps

        The mp3car store now carries the esi-pro gigaport. Might be another option for you. I'm not sure what brands are easier for you to find in Europe.
        System always under construction

          You could also use a high to low level signal adapter. I use that with my Infill G4 to convert the signal so I can send it to my amp. I am running the high output channels to that converter for my front speakers, then into my amp. I am running my rear speakers straight into the Infill. Sub on sub out. This thing cost me about 40. Do a search for Zealum. With this thing you can adjust the output voltage, it is really handy!
