Wiring Connections For Audio Jacks. Audio plugs can come with as few as 2 conductors up to 6 or more conductors. But since speaker wire connectors house and protect the bare wires the experience of pluggingunplugging audio is greatly simplified not unlike using RCA jacks.
The balanced audio cable has a structure similar to an unbalanced cable but with a ground wire. The datasheet states that its a 3-pole stereo jack socket - for the first plug in Figure 1. Wiring diagram showing stereo connections for mm headphone plug Now.
For this example we will focus on the standard stereo connector with 3 conductors.
The balanced audio cable has a structure similar to an unbalanced cable but with a ground wire. Now use multi-strand wires to solder with the pins and then again cover it with the Plastic casing. Remove the above plastic casing and you will see the pins of the jack as shown in the images above. It transmits two copies of an equivalent incoming audio signal known as positive hot and negative cold.
