Catchbox Plus setup - balanced and unbalanced audio outputs

Balanced and unbalanced audio outputs and inputs, as well as the cables used to connect them, have different wiring. Therefore it is important to be sure the connection is correct. In some cases, incorrect setup can lead to audible noises or no audio at all. You can read more information about balanced and unbalanced cables and signals here

Catchbox Plus receiver has three audio outputs:

  • 6.3 mm / ¼ in jack socket - unbalanced, line level
  • XLR - balanced, Mic level
  • USB-C - digital
