An arrangement for introducing audio-frequency signals into a power supply line containing a compensating capacitor, through a junction converter having primary winding which is connected with an audio-frequency signal generator. The secondary winding of the junction converter is connected in series with the compensating capacitors which are not located in a parallel branch line to the secondary winding of the junction converter, and thus do not represent a load on the audio-frequency signal. The audio-frequency signal is coupled into the power supply line through the compensating capacitors which are connected in series with the secondary winding, whereby the coupling in is effected, on the one hand, through one and, on the other hand, through two parallel-connected compensating capacitors.
