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?

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.
