“AUDIO INPUTS”, “AUDIO OUTPUTS” audio network interface in RGB matrix switchers can be connected
to the audio signal and amplify sources. Audio connection is little more complicated than video. It has two
types of connection: balanced and unbalanced. The balanced connection transmits a pair of balanced sig-
nals with two cables. Because Interferences will have the same intensity and the opposite phases on the two
cables; it will be counteracted in the end. For the low frequency extent of the audio signal, it would be easily
interfered under long distance transmission. Therefore as an anti-interference connection, it is mostly used in
Audio connection of special high end devices.
