How XLR Cables Work
The balanced connection of XLR cables is the key to their superior performance. In a balanced connection, the audio signal is transmitted as a differential signal, meaning it is sent as two identical signals, one positive and one negative, over two conductors. The receiving device then subtracts one signal from the other, effectively canceling out any noise that has been induced into both conductors. This process significantly reduces electromagnetic interference (EMI) and radio-frequency interference (RFI), resulting in a cleaner and more accurate audio signal.
Advantages of Balanced Connections
The use of balanced connections in XLR cables offers several advantages, including:
