Description
DEUTSCHESGERMAN
Die Erfindung betrifft eine vorteilhafte Pegelausgleichsregelung für Stereo-Tonwiedergabeeinrichtungen, und zwar unter Verwendung eines sogenannten Wechselreglers bzw. Wechselpotentiometers, wie sie an sich in der Rundfunktechnik bereits Verwendung finden.The invention relates to an advantageous level compensation control for stereo sound reproducers, using a so-called Change regulator or change potentiometer, as they are already used in broadcast technology Find.
Die Erfindung besteht darin, daß ein derartiger Wechselregler für die Pegelausgleichsregelung für die Stereo^Tonwiedergabe ausgenutzt wird, und zwar wird das besondere Kennzeichen darin gesehen, daß eine Potentiometervorrichtung in Form eines derartigen Wechselreglers zwischen Verstärker und Lautsprecher beider Stereo-Tonkanäle einer Stereo-Tonwiedergabeanlage vorgesehen ist. In Durchführung dieses Erfindungsgedankens sind die Enden des Wechselregler-Widerstandes an je eine Leitung der beiden Lautsprecher und der Verbindungspunkt beider Abgriffe dieses Widerstandes an je eine Ausgangsleitung der den beiden Tonkanälen zugeordneten Verstärker geführt. Es ist vorteilhaft, vorzugsweise in der Mittelstellung des Reglers, in der der Reglerwiderstand abgeschaltet und damit beide Lautsprecher voll eingeschaltet sind, eine Rastvorrichtung vorzusehen. The invention consists in that such a change controller for level compensation control for the stereo ^ sound reproduction is exploited, namely the special characteristic is seen in that a potentiometer device in the form of such an alternating regulator between amplifier and Loudspeakers for both stereo sound channels of a stereo sound reproduction system is provided. In carrying out this inventive concept, the ends of the changeover regulator resistor are each connected to a line two loudspeakers and the connection point of both taps of this resistor to one output line each the amplifier assigned to the two audio channels. It's beneficial, preferably in the middle position of the controller, in which the controller resistor is switched off and thus both loudspeakers are fully switched on to provide a locking device.
Es wird also der Regler einfach zwischen die beiden Verstärker-Ausgänge und die zugehörigen Lautsprecher der Stereo-Tonwiedergabeanlage geschaltet. Es sind dadurch am Verstärkerchassis weder elektrische noch mechanische Änderungen erforderlich. Aus diesem Grunde eignet sich die Erfindung auch gut zum nachträglichen Einbau in Stereo-Musikschränke bzw. -Truhen. Der Regler kann für diesen Fall z. B. im Phonofach, in der Mitte der Schallwand oder sonst irgendwie im Gehäuse untergebracht werden. Da die Regelschaltung niederohmig ist, ist die \^erdrahtung völlig unkritisch.So the controller is simply placed between the two amplifier outputs and the associated ones Loudspeakers of the stereo sound reproduction system switched. There are neither on the amplifier chassis electrical and mechanical changes required. The invention is suitable for this reason also good for retrofitting in stereo music cabinets or chests. In this case, the controller can, for. B. in the phono compartment, in the middle of the Baffle or otherwise housed in the housing. Because the control circuit has low resistance the wiring is completely uncritical.
Die Einrichtung gemäß der Erfindung sei an Hand eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist, näher erläutert.The device according to the invention is based on an embodiment shown in the drawing is shown, explained in more detail.
1 und 2 sind die Endklemmen des Widerstandes 7 des Wechselreglers. 3 ist der Verbindungspunkt bzw. die Klemme der beiden zueinander starr angeordneten und gemeinsam bewegten Widerstandsabgriffe 8 und 9, die gemäß der Eigenart des Wechselreglers wechselweise auf dem Regelwiderstand 7 schleifen, wie dies ohne weiteres aus der Zeichnung hervorgeht. Die Klemme 1 ist mit der Leitung 4 des Lautsprechers I und die Klemme 2 mit der Leitung 5 des Lautsprechers II verbunden, während die mittlere Klemme 3 sowohl an die Leitung 6 des Ausgangs des Verstärkers I als auch an die Leitung 7 des Ausgangs des Verstärkers II gelegt ist. Wird der Regler nun.1 and 2 are the end terminals of resistor 7 of the changeover regulator. 3 is the connection point or the clamp of the two resistance taps 8, which are rigidly arranged with respect to one another and moved together and 9, which alternately slide on the variable resistor 7 according to the nature of the variable speed controller, as is readily apparent from the drawing. Terminal 1 is connected to line 4 of the loudspeaker I and terminal 2 are connected to line 5 of loudspeaker II, while the middle Terminal 3 to both line 6 of the output of amplifier I and line 7 of the output of the amplifier II is placed. Will the controller now.

in Richtung des Pfeiles nach links gedreht, so wird der Lautsprecher II leiser, d. h., es wird der Stereos-Kanal II beeinflußt. Betätigt man den Regler in Richtung des Pfeiles nach rechts, so wird der Regelwiderstand mehr oder weniger in den Tonkanal des Verstärkers I eingeschaltet, und dementsprechend wird der Verstärkungspegel im Tonkanal des Verstärkers I geregelt. Man kann also durch einfache Betätigung dieses Reglers beide Tonkanäle besonders aufeinander abstimmen und den Verstärkungspegel ausgleichen.If you turn it to the left in the direction of the arrow, the loudspeaker II becomes quieter, i.e. that is, it becomes the Stereos channel II affected. If you operate the controller in the direction of the arrow to the right, the rheostat is increased more or less switched into the sound channel of amplifier I, and accordingly the gain level in the audio channel of amplifier I. So you can simply press of this control adjust both audio channels to each other and balance the gain level.
