For PA (public address) speakers, you would typically use unbalanced cables, as this is the more common method for these types of speakers. One end of the cable connects to the mixer or amplifier, while the other end connects to the PA speaker. These cables are also known as TS ( tip-sleeve) cables, where the tip is the hot signal and the sleeve is the ground.

However, if your PA speaker system has an input that requires a balanced connection, then you would need to use a balanced cable, such as a TRS (tip-ring-sleeve) cable. Balanced cables are less susceptible to interference and noise, so using them would improve the signal quality.

To sum up, unbalanced cables are the norm for PA speakers, but check your specific equipment to see if a balanced connection is required.
