Unbalanced Line

A communications line that uses circuit common or "ground" as a return path. In the case of intercom systems, in general, an unbalanced line is more susceptible to noise interference. But practically speaking, a low impedance unbalanced line (200Ω) works well in the real world, and has the added advantage of being able to operate on just two wires, carrying the DC power, the full duplex audio signal, the 20.000kHz call light signal, and the 24.000kHz microphone reset signal. Many installations have been previously wired for telephone operation and the two-wire intercom works on these pairs. A special "golf" system application of the TW system has the advantages of the TW system and balanced line operation. A standard TW power supply operates a string of beltpack or other user stations in an isolated, balanced mode. The balanced system is transformer coupled into the regular unbalanced system.
