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? Try a Boostaroo headphone amp, which RS calls a 33-118. if you're going that route, might try the FIIO amp; they're selling all over ebay for like $4 plus postage from the far east. i got mine from an outfit called justforlive2008, and it arrived within less than a week for $3.59 postage, right to the house without my having to go to the store. that's cheaper than us postage, and faster. |

I only compute 2v for that device. Meaning its power supply should develope at least 6 volts with the 1.5 v battery. greg |

I modified mine with some wooden dowels that simulate AA cells, so that it runs off of 5 vdc from an external source. However, its still limited to just under 2 vrms output. Nevertheless, it helps. Plan B - try a Behringer headphone amplifier: http://www.behringer.com/HA400/index.cfm?lang=ENG http://www.behringer.com/AMP800/index.cfm?lang=ENG |
