Description
Die Neuerung bezieht sich auf eine Anordnung zur zusätzlichen fernbedienbaren Lautstärkeregelung in Rundfunk- und Fernsehgeräten mit eingebauter, gehörrichtiger Lautstärkeregelung. The innovation relates to an arrangement for additional remote control Volume control in radio and television sets with built-in, aurally accurate Volume control.
Es sind bereits Anordnungen zur fernbedienbaren Lautstärkergelung mit zwei Fernleitungen und einem einfachen Regelglied Potentiometer) bekannt. Bei diesen bewirkt die Verstellung des Regelgliedes eine Gleichspannungsänderung, die den Arbeitspunkt einer Verstärkerröhre verschiebt und so eine Verstärkungsänderung hervorruft. Infolge der Verschiebung des Arbeitspunktes der Verstärkerr8hre können jedoch, wenn das Niederfrequenzsignal nicht entsprechend dosiert wird, leicht Übersteuerungen und damit Verzerrungen auftreten. Außerdem kann eine derartige Regelung nicht gehörrichtig gestaltet werden. There are already arrangements for remote controllable volume control known with two long-distance lines and a simple potentiometer control element). at this causes the adjustment of the control element a DC voltage change, the shifts the operating point of an amplifier tube and thus a change in gain evokes. As a result of the shift in the working point of the amplifier tube however, if the low frequency signal is not dosed appropriately, it is easy to overdrive and thus distortions occur. In addition, such a regulation cannot be aurally correct be designed.
Die Neuerung hat zum Ziel, eine einfache Anordnung zur fernsteuerbaren
Lautstärkeregelung zu schaffen, die nur zwei Fernleitungen benötigt, die die vorgenannten
Naohteile vermeidet und die gehörrichtig arbeitet. Sie besteht
Nachstehend wird ein Ausführungsbeispiel der Neuerung anhand der Zeichnung beschrieben. Hierbei zeigen Fig. 1 das Schaltbild einer neuerungagemäßen Anordnung im Zusammenhang mit dem NF-Teil eines Rundfunkgerätes, Fig. 2 die mit der Anordnung erreichte gehörrichtige Lautstärkeregelung.An exemplary embodiment of the innovation is shown below with reference to the drawing described. 1 shows the circuit diagram of a novel arrangement in connection with the NF part of a radio device, Fig. 2 with the arrangement Aurally accurate volume control achieved.
Das Niederfrequenzsignal wird am Anschlußpunkt a einem im Gerät eingebauten
Lautstärkeregler 1 zugeführt. in Verstärkerröhren 2 und 3 verstärkt und über einen
Ausgangstransformator einem Lautsprecher 5 oder einer Lautspreohergruppe zugeführt.
Der eingebaute Lautstärkeregler 1 ist
An den Fußpunkt c ist außerdem eine mit einer Sekundärwieklung 14
des Ausgangstrafos 4 verbundene Leitung angeschlossen, die in den Fußpunkt o eine
