Balanced output stage + component picks

Three days until Christmas and I got a lot done again today. I think that must be the longest workday I've ever managed in all of Blueprint. My eyes hurt.

In any case, my GitHub Copilot requests were definitely put to the test. After what felt like 1000 questions, I finally built the balanced output stage after the DAC for the first output. The others just need to be duplicated seven more times tomorrow.

then spent the rest of the day selecting the components and filling in each symbol with LCSC numbers and properties.

Research and the DAC chip

So, a new project for the last few days of this year. I've already built the mainboard and the analog-to-digital module for my own digital mixing console. Now it's time for the digital-to-analog module. The main chip is the AKM AK4458VN, an 8-channel, 115dB, 768kHz, 32-bit digital-to-analog converter. As always, the first few hours were spent looking up the datasheet and reviewing numerous projects where this chip was used. I then used the pin headers that come from the mainboard with all the necessary connections and connected the chip in the schematic file. The decoupling capacitors are still missing, though.
