Hello fellow DIYlers,
this is my first post and because it its and i am asking the "how to" question, i hope im not asking too much and disregard any of the forum rules.
For life performances in quadraphony i am missing a certain thing which, if i would know how to build, would be very handy. It would be line channel strip. which recieves audio line signals in stereo from a sound card (rme ff800) and does the following
and simply return the signal to be fed into speaker amps. This seems fairly doable as there already some modules in the market (like the 3 band eq). On top these basic functions i would like to add another feature: A 2 way crossover circuit that has 2 potis. 1) the frequency on where to split the signal into two. 2) a poti that acts like a sort of crossfader. position 0 routes everything to the first channel/main out - no splitting. in middle position there is 50% and in full 100%, main channel will carry only the lower frequencies and the aux hi channel everything above. to be honest - i can not even explain by technical terms what happens between 0% and 100%. its sort of crossfader frequency splitting.
this is exactly the part where i can not even explain the behaviour that well and ask you guys if its possible and how.
In any case - it would be really great that i would get the basic features a simple line channel strip done. for that i would be really happy to collaborate - im good in diy other things have all soldering gear and some experience. i can offer other things in return - i am a graphic designer and web developer.

- amplify the sound if required
- have a fixed frequency 3 band equalizer +- 15 db
- a line fader to control volume
- a switch on/off to route signal to a headphone out
and simply return the signal to be fed into speaker amps. This seems fairly doable as there already some modules in the market (like the 3 band eq).
