NCED There two basic ways to transport an audio signal with microphone or line level Un balanced line Utilizing a two conductor cable it transports the signal as the voltage between them Electro magnetic interference can get added to the signal as undesired noise Connectors that carry un balanced signals have two pins such as RCA Phono and 1 4 6 35 mm often referred to as jack mono 3 pin connector such as XLR Cannon may also carry un balanced signals if one of the pins is unused Balanced line Utilizing a three conductor cable one of them acts as a shield against electro magnetic noise and is the ground conductor The other two have the same voltage with respect to the ground conductor but with opposite signs The noise that cannot be rejected by the shield affects both signal conductors in the same way At the device s input the two signals get summed with opposite sign so that noise is cancelled out while the programme signal doubles in level Most professional audio devices use balanced inputs and outputs Connectors that can carry balanced signal have three pins such as XLR Cannon and 6 35 mm stereo The graphs that follow show the recommended connection with different types of connectors to balanced processor or amplifier inputs The connectors on the left hand side come from a signal source and the ones on the right hand side go to the inputs of the processor or amplifier Note that on the un balanced c
