hum... actually i wanted to use 10k pots because i wasnt able to hear any sound when testing with my phone (even though its VERY loud), but later i want to use it for prosounded gameboys and the like. should i rather use higher resistances then?

Well. Higher resistance makes the sound weaker. So I think the general consensus regarding my attempt earlier is that you need to find a resistance value that works fine for what you expect to use it for? *shrug*
* Also my two Game Boys are prosounded and 2k ohm resistance still made the sound very, very weak.

yes, the inputs in my mixer go into an amp before going out

I call it "Moxx". For whatever reason.
But uh, I tested it out with headphone jacks instead, and much to my expectation the sound was quieter than the prosound jack produces. I don't really know what to think of this. It seems to work kind of like it should? *shrug*
But to tell you the complete truth I may have overlooked that prosound detail regarding plugging headphones into it... ^^;

Look up on youtube "Altoid Tin Headphone Amp" - try implementing that. That way you can have a potentiometer on the box which lets you control the volume. Will need a 9V battery or other power supply though.

OK. I'll look it up. The reason why I ditched the potentiometers is that I can't fit them inside that case sooooo... the potentiometers go on the next design. :3
@Alley Beach: that looks quite good, I'll look that over.
Thanks for the pointers, guys.

Made myself a portable little passive mixer today, I've got parts on the way to make a second one if anybody is interested...

Hi,
First post here. I was looking for something similar and was redirected here from another audio forum.
I have two audio sources:
1. Computer sound card
2. Custom Handsfree USb device
Both devices have 3.5 female jack.
the two sources are going to be used with one single amp (car amp)
The computer sound card is muted when sound is coming from the second device.
I need to make both devices use the same amp.
Can you make a 2 inputs passive mixer please?
I don't need to adjust volume with the mixer. volume is controlled via software on the computer.
Thanks.
