DIY mixers

[Tony Allgood]

Hi,

I will second Jules thoughts. A small mixer is fine for diy, use the
Scheaffer-apparatabau program for your front panel and you are away. If
its small then you don't have to bother with virtual earth busses, just
sum all the voltages at the master. If you do go down the virtual earth
bus route, my tip would be to use balanced virtual earths to keep hum
and shit down to minimum. And don't forget to make it expandable... you
never know when you will need those extra channels. The only problem you
will find is boredom, a ten input channel desk like mine became a bit of
a drag and had the pcbs done for me. Mind you a good vocoder would
suffer from the same repetitive thing as well. All those channels... all
nearly the same... yawn.

I have successfully built several DIY mixers. It was quite a learning
experience but worth it. Parts ended up costing close to $8-900 for
my main board which a has 40 inputs. It is strictly a line level
afair. I have had real good results with smaller ones. Definately a
labor of love compared to flipping burgers part time and saving up
for a mackie!
