I think trying to quantify music is one of the biggest wastes of time in the world, like discussing your favourite colour or deity or pizza topping. People should realise that and get on with their life.

Thanks

May i ask what components i need to built a 4x4 passiv matrix mixer :

what jacks do i need for normal 1/4" instrumentcable ?

what resistors and potentiometer ?

what sort of "cable" to link the innerlife?

Would be great if someone can help a newblie. :oops:

Thanks guys and girls :)

You will need.

4x4 (16) pots (any value 10-100K all the same)
4+4 (8) jacks
Some wire
A box

again thank you very much.

there are resistors from 0,25 to 5 W with 100kOhm which one should i choose and why?

is there anything i have to take care of while choosing the jacks? mono/ stereo

1/4W is fine, you won't be burning much power.

ok i will first try a 3x3 matrix mixer ... think the schematic builtup looks nearly the same but i will try to find one.

i want to use

9x 6,3mm stereo open jacks
9x 100k pots
9x 100k ohm 0,25 w resistors

wire,knobs,case ...

pls let me know if this components can finely work together and i will order the stuff :)

big thanks again Misomusist :D

The resistor values are a bit high, that's going to mean you always have a miniumum of 100K in each circuit, I'd drop them by a factor of 10, so I'd get 9 x 10K resistors, but anything between about 2K and 20K is probably going to get you in the ballpark.

Got given a TLE2426IP virtual ground I and have bought a 24v DC wall wart to hopefully make a +/-12v pay for my matrix mixer soon :)

Burned out the TLE2426ip somehow while trying to connect that up, dumb ;__;

gonna just use 2x 12v DC power supplies, stupide

"Hammond enclosure" is a search term that will help

If you are in the US AmishRobots hooked me up with this site.

If you're trying to split power supplies a metal case might make it difficulter :mrgreen:

Hammond is a Canadian manufacturer, are they still available in the Republic of England?

Dunno if literally made by Hammond but enclosures of the same standard sizes are commonplace, our electronics chain Maplin sell some even... & there's loads on eBay from all over, cheap Chinese ones, coloured powder-coated ones etx

You mean stack a virtual ground on a single pole supply & reference that on the enclosure? Just don't reference either leg of the PSU - only the virtual ground.
I have no suggestion for software.
