Following the pinout diagram from the manual of the card I connected pins 8 & 9 and 22 & 23 with the ground (shield) wire of the cable that connects the balanced Inputs and Outputs with the mixbuss card. Then I read some info about floating ground and I noticed the 0V marking on the diagram for these pins, just like the pins 14-17 which I connected to the 0V DC output from the PSU regulator. Have I done something wrong?
