Balanced lines use three wires with the outside wire being a shield around the inside two. The inside two wires are thus shielded from external RF.
Unbalanced audio lines use just two wires, there is no shield. The signalpasses down the two wires unshielded from outside RF.
XLR is also recommended in long(er) interconnects
The unbalanced input impedance of the preamplifier is at worst case 10 kOhms. In balanced mode, the input impedance is higher, with a differential impedance of at least 20 kOhms.
I made it a point to use all XLR in my setup..some systems often respond better to Balanced configuration
I replaced my XLR with RCA (3.5m) and I got a slight buzz..
