They are, however, still susceptible to the noise that unbalanced signals are prone to in these scenarios. If you find yourself in a situation that requires unbalanced audio cabling, make sure to cross them perpendicularly to any power cable they may encounter.

Return to BoxCast. One carries positive, the carries negative and is also used for ground. The advantage of a balanced signal is that because the ground is seperate from the negative conductor, there is less chance that radio frequency interferance will get into the audio signal.

The high gain and isolated ground make for a cleaner, noise-free signal. If cable runs are shorter, there should be no problem with RF interferance or noise on unbalanced, db signals. If you have RF problems in your studio, you probably have some kind of ground fault, and it's a good idea to have it checked out by an electrician. The cable construction will be important in order to understand why the first two cables can support balanced connections and the second two cables cannot.

A balanced circuit is a two-conductor circuit in which both conductors and all circuits connected to them have the same impedance with respect to ground and to all other conductors. The purpose of balancing is to make the noise pickup equal in both conductors, in which case it will be a common-mode signal that can be made to cancel out in the load.

A balanced receiver uses a differential device, which will only respond to the difference in voltage between the two wires of the interconnecting cable. This is an example of a differential-mode signal, because there is a different voltage on each wire. This is an example of a common-mode signal, because there is a common voltage on each wire. It results in common-mode rejection. This is where it gets really interesting, because we can use this to our advantage!

Imagine an audio signal sent across one of the wires. When it reaches the differential device, it is allowed to pass through. However, along the way there is some noise from nearby electronics that induces voltage onto the wires. There are two important details about the cable that make this noise cancelation possible.
