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!
