small amp for headphones

**ren** · 07-01-2004, 08:52 AM

Okay, here's the thing. I'm putting an XBox in my car and only want headphones for audio. However, the audio out from the xbox is not nearly strong enough to power headphones. So, I need some kind of small in-line amp (maybe even with volume control) that I can run in between the xbox and the headphones. It would ideally have RCA in and mini-stereo out.

Has anyone seen ANYTHING like this?

search for "headphone amp" on google. there are a TON of project sites that have DIY projects for this exact purpose... the only hard part is finding the parts to work in a 12V environment. i may have some paperwork here for op amps for 12V input... i was thinking of doing the same thing for my playstation.

yeah, i've found lots of DIY kits, but I'm a little strapped for time (need it in about 2 days). otherwise, a kit would be great, and probably save me lots of money.

if you have decent spare set of computer speakers u could rip the amp out of that

Better yet, search google for 386 amplifier. The 386 chip can use 12v and doesnt require a negative supply like most opamps.

The chip can be found at Radioshack:

For a stereo amp, use one of these pots:

Radioshack should have all the other parts you need.

I am not sure if you are looking to build one like the previous posters suggested.

Initially, I was looking for you on froogle.com for just a single headphone amp and could not find anything after a few mins of looking. Since you may be playing multiplayer you want multi chanels; so in that case, the ART HeadAMP looks good. For seperate headphone outputs. I did a quick froogle for it and the lowest price yielded the following ebay auction which has 5 at a buy it now price of 43.99. There are also others on froogle.

Hopefully, this helps you out.
