Small mixer

Here's a small mixer that i'm working on. It may not seem like much, but for me this is quite a large undertaking. It's not really something I need so i'm building this purely as a personal challenge.
  • 4 channels with gain, eq, pan and volume
  • Good preamps with balanced direct outputs
  • 3 band active EQ per channel
  • VU metering, switchable for each channel or main L/R
  • Balanced stereo output
  • Headphone output in stereo
  • Good quiet regulated powersupply

I made my own vero layout for a preamp based on the INA217 datasheet. It sounds very good!

Looks great! On your layout, what does ut- and ut plus stand for?

Thanks :) Ut means out (wrote that in swedish by accident). It's a balanced output hence the plus and minus.

How are the capacitators orientated?
And yes Phantom power would be great!
