OLAH Arran. My Obvious experience in two options:
1.- Connect RCA Output (rec output // Master 1 output or Booth output with volume output, of course) To Input U-Control UCA202 and USB to Laptop
Check the Soundcard inputs in Record Software to be sure the sound is entering in Record program like Audacity or other.
2.- Connect RCA Output (rec output // Master 1 output or Booth output with volume output, of course) To Input micro/headphones Laptop with an RCA/Minijack stereo cable
Check the Soundcard inputs in Record Software to be sure the sound is entering in Record program like Audacity or other throw the mixer Windows audio settings.
