Note for stage sound equipment microphone commissioning: generally balance signal; but for short lines, in relatively low noise, but for longer lines, the determinfactor is the level of electromagnetic interference in the surrounding environment, which is recommended.

In professional sound engineering, it is possible to balance the circuit with twisted pair wire, shielding wire to transmit signals, but if the non-balance circuit with shielding wire, usually and the balance circuit connection method is different. 

Connecting cables for non-equilibrium signals are usually shielded, so the center cable of the signal end (hot end) usually has a ring of metal mesh, and the metal mesh is usually connected to the ground end of the plug. Shield cable as the most effective method can usually prevent noise from mixing into the audio signal.

But for unshielded cables, often called zip cables, their main function is for the connection between the power amplifier and the speaker.This is because the signal from the power amplifier to the speaker is amplified and the level is so high that the noise is not enough to affect it. 

Through the above introduction, we can see that the equilibrium connection method can be converted to non-equilibrium, so you only need to remove the cold end or shield and cold end short connection, common in phoenix head, Cannon head, three core, etc.Non-equilibrium is not normally translated into equilibrium (unless there are extra lines available for connection). 

In the actual wiring of professional sound engineering, if the normal sound of the song and music is very small or not, it is generally transmitted by the unbalanced signal by the balance cable, so you just need to change the cable to the non-balance.
