thanks for your answers,
so i think the mbmixer goes the right way (volume is controlled via resistor network right?)
Can i use the pga2311 chip instead the pga4311 (think is better for soldering)?
I don´t need panorama control so i can use the pga2311 as double mono chip.
With 16 pga2311 i can realize a 32 channel fader mute automation, right?
About Wiring:
My Idea is to wire the pga2311´s instead my analog 10k log faders.
How is this done?
Is there a need in opamps in front of pga2311 ?
