    How can I increasing output voltage/amplify my laptop's sound card
    headphone jack. Tia sal2

    Greetings All

    I'm generating different sound waves using my laptop
    and outputting the sound via my laptop's sound card headphone jack.

    I need to increase the output voltage / amplify the output
    signal to at least 5v while not adding to much noise to the
    signal. What's the best way to go about this?
    Preamp/Amplifier/mixer Can anyone recommend a low cost solution?

    thanks sal2

    Sorry it this is repeated had problems with my posting server

    At the risk of being overly obvious, what's wrong with
    simply connecting the line-level outputs to an amplifier?
    If cost is a concern, your local Radio Shack, Circuit City,
    etc. no doubt have some cheap amps to choose from.

  3. I might be going in totally the wrong direction here, but I'm sure that
    someone will correct me. If you're just looking for increased voltage
    (not increased power), what about an audio transformer?

    He probably means power. increasing the voltage output to 100 v doesn't mean more audio.Well anyhow you coulduse usb port and get more juice 5v and max is .5a But that is lame idea make and design and buy enclosures for whatever cheaper to buy any time any day without problems as the man sugested BUY.
