do you know of any good diy-audio-mixer project on the net ?
something good quality and easy to build !
with schematics and all !
something like this project only for audio-mixer
Hi,
I guess your asking for something that doesn’t exist 
I came across this project:
http://sound.westhost.com/project30.htm
But even with “modest” specs (3-band eq, semiparametric mid. 2 aux ect.) it’s pretty complex.
Bye, Moebius
These days, it is not so cool to build your own mixer. (too expensive, when there are such cheap commercial units) Unless you need a custom device that can’t be bought.
I spent Aus$700 in the mid 90’s bulding an 8 channel live sound mixer, (School project) but ran out of money at 4 channels! Now it sits in a cupboard!
If you have trouble finding circuits, and PCB layouts, I can help you out there, but the design is very old, (maybe 20 years) and with very simple features, only 2 FX sends, 3 band EQ, and not much else. No inserts or anything!
But you really start to learn how analogue audio works, especially signal flow in a mixer!
I think it would be very cool to build an automated (volume level only) mixer, using Thorstens AOUT modules, and VCA’s though! Or even using the MF module, with Motorfaders that have an extra track for audio signal, but these are very expensive!
there is a very busy forum for analogue audio… diyaudio.com
I always thought that’s a hard ( too hard ) DIY project …
About price … commercial will be always cheaper …
About quality … there’s a big work in the PCBs and the chip choice ..!!!
I don’t want to make you abandon the project .. but it seems to be too much effort for a commercial solution that you can find anywhere …
Theres so much different mixer out now …
:-/
maybe cheaper and easier to build a digital mixer… (and you can find lot of useful stuff on our adat, sblive, and that’s stuff project!!! hehe ;D)
Hi,
a good mixer is not always hard & expensive to build. It depends strongly on what you want (or expect).
There are a lot of DIY resources with audio projects.
Just take a look at www.ePanorama.net, especially on the following links (mixer):
http://www.epanorama.net/links/audiocircuits.html#mixer
There you can find a lot of projects. I built a big analog modular mixer several years ago. It was a project called “ESP Audio pages”. I don’t find the link now. Just surf a little in ePanorama.net .
Hope this helps
Doc
actually , the link at the top of the page is the esp link…
so you found it once more!
You could have a look at the http://www.paia.com kits
