Title (EN) CROSSOVER CIRCUIT
(FR) CIRCUIT DE COUPURE
Abstract: front page image
(EN)Crossover circuit intended to be mounted in loudspeaker boxes with at least two loudspeaker elements (1, 2) and arranged to divide an incoming electric signal in respect of its frequency. High frequencies are thus directed to the loudspeaker element (1) intended for high frequency reproduction, and low frequencies are directed to the loudspeaker elements (2), intended for low and/or intermediate frequency reproduction. In order to improve the transient reproduction and also to improve the reproduction of the spacial, sound information a new type of parallel resonance circuit has been brought into the crossover circuit. The parallel resonance circuit mainly consists of an inductor (9) arranged in series, a capacitor (10) connected in parallel to said inductor, and a further capacitor (11), in series with a resistor (12), is connected in parallel to said inductor and capacitor.
(FR)Un circuit de coupure est destine a etre monte des enceintes de haut-parleurs avec au moins deux elements de haut-parleurs (1, 2), et concu pour diviser un signal electrique d"entree par rapport a sa frequence. Des hautes frequences sont ainsi dirigees vers l"element de haut-parleur (1) prevu pour une reproduction de hautes frequences, et des basses frequences sont dirigees vers l"element de haut-parleur (2), prevu pour la reproduction des basses frequences et/ou des frequences intermediaires. De maniere a ameliorer la reproduction transitoire et egalement ameliorer la reproduction de l"information spatiale, sonore, in nouveau type de circuits paralleles de resonance a ete inclus dans le circuit de coupure. Le circuit parallele de resonance consiste essentiellement en un inducteur (9) monte en serie, un condensateur (10) connecte en parallele a l"inducteur, et un autre condensateur (11) en serie avec une resistance (12) est connecte en parallele auxdits inducteur et condensateur.
