10. APPENDICES 

 

Appendix A. Line connections : un-balanced and balanced 

 
There are two basic ways to transport an audio signal with 
microphone or line level: 
 

  Un-balanced line: Utilising 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 ¼” (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: Utilising 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 ¼” (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 connectors on the left-hand side, two terminals are 
joined inside the connector. If hum occurs with balanced to 
balanced connections, try disconnecting the sleeve (ground) 
on the input connector.
