Abstract
A device has a standard female audio connector that is capable of receiving four-pole male connectors and three-pole male connectors and implements: means (CTRL, VCC, S) for selectively transmitting a DC power supply signal via a first pin (DP) of said connector; means (CTRL, ANC) for selectively activating a cancellation mechanism for ambient noise from digital audio signals that are intended to be received, via the first pin, in a manner superimposed on said DC power supply signal; means (CTRL, MIF) for selectively transmitting via a second pin of said connector, in a manner superimposed on said audio signals, a timing clock that is intended for digital microphones (DML, DMR) or other sensors; means (CTRL) for configuring itself vis-à-vis the DC power supply signal, the ambient noise cancellation mechanism and the timing clock, according to a determined type of listening device that is effectively connected via said connector.
