Abstract (en)
[origin: WO9938355A1] The present invention concerns a method and an arrangement for connecting a microphone requiring a bias voltage to an audio device for establishing voice signal communications therebetween, wherein the interface comprises several inputs for the microphone. The inventive method comprises steps of supplying a biasing voltage to the microphone through at least one of said several inputs for the microphone such that the biasing voltage is conducted through a diode which is disposed on a respective one of the conduits from said inputs, and transmitting the voice signal from the microphone to the audio device through another input of said several inputs.
