Page 21: Plug And Connection Assignment
In a professional environment, therefore, the balanced transmission is preferred, because this enables an undisturbed transmission of signals over long distances. In addition to the conduc‐ tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers the signal, but phase-shifted by 180°. PA 108 A... - Page 22 Plug and connection assignment Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized. The result is a pure signal without any noise inter‐ ference. XLR plug (balanced) Ground, shielding Signal (in phase, +) Signal (out of phase, –) XLR plug (unbalanced) Ground, shielding...
