In that respect the invention is based on the idea of providing a detection device which is capable of distinguishing whether a microphone or audio signal processing arrangement connected thereto operates on an analog or digital basis. An analog or digital connection is selected in accordance with that determination procedure. Consequently there is provided a detection device which has a sensing device (6), a determining device (5) and a selecting device (4). The sensing device (6) senses an external signal fed to the detection device and forwards that signal to the determining device (5). The determining device (5) determines whether the sensed external signal was transmitted by an analog or digital signal processing apparatus and transmits a corresponding determination signal to the selecting device (4). The selecting device (4) then selects either an analog or a digital connection, in dependence on the determination signal.
