While using Parametric Equilization. I set my A and B to 60hz and above and I tried to set C (what I thought was the subwoofer) to 60hz and below - but it just made it so the right channel didn’t play any audio. Is one of them for the subwoofer? I was able to just set A+B and then set the sub crossover in its own app - but I’m curious about that. Second - using the Hifiberry room measurement - should I be moving the microphone a bit between each of the four sound tests? Should I use REW instead? Would it be a significant improvement? I can I’m just not sure how to load those files into Hifiberry OS afterwards.

  Sounds like your right channel is connected to the C output

  No, we don't recommend this. In the important frequency range <200Hz, this won't make a difference.

  Feel free to try. We feel, our RoomEq wizar is easier to use. REW has lots of options and you need to be careful not to create over-optimized settings that try to create a perfectly flat frequency response. This will create lots of filters without improving sound quality.

  Thank you. I initially forgot to mention that I have a DAC+DSP card - so I wasn’t sure where the “C” channel confusion was coming from. But I also realized how is the card supposed to know I have a subwoofer?

  Given the above I have everything setup correctly. It’s sounding great but I wanted to know.
