This is different from the usage on 4-wire circuits. The colours in this diagram correspond with the colouring in figure 2. An example of balanced lines is the connection of microphones to a mixer in professional systems. Classically, both dynamic and condenser microphones used transformers to provide a differential-mode signal [citation needed ...
