Info taken from ofsoundmind site:

Balanced connections entered into the mobile audio scene from the Pro-audio industry. Pro gear such as mixers, microphones, processors, and so on all operate using balanced connections. Your home audio  tape deck, CD-player, DVD, VCR and turntable all use an unbalanced connection.

Most balanced connections are made using an XLR style connector.

Unbalanced connections are made using RCA style connectors.

Unbalanced connections for the most part use a center conductor and a ground shield. Balanced connections, on the other hand, use two phases relative to ground. A positive and negative, and a ground. The positive and negative signals are exact opposites of each other in phasing, but are of equal amplitude. When a balanced signal is processed, it amplifies what is different and ignores what is the same. This method has greater noise reduction, as the noise is generally shared between the positive and negative conductors and is therefore filtered out.
