Circuit arrangement of electronic analog crossover networks for active loudspeaker systems

摘要

The two series -linked first and second single gates (2), of which at least one has a frequency dependent impedance, are connected to the source (0) of the input signal.The inputs of the first differential amplifier (4) and the second one (2) are connected in parallel to the first one (1) and to the second one (5).The output of the differential amplifiers shall be connected to the input of the power amplifiers of each speaker.Instead of a pair, the source (0) of the input signal may be connected by a triangle of series -linked single -gates, of which at least two have frequency -dependent impedance.In this arrangement, the first differential amplifier inputs (4) are connected parallel to the first one -gate (1);to the second one -gate (2) the inputs of the second differential amplifier (5) and the third one -gate (3) the inputs of the third differential amplifier (6).
