Abstract

Passive Lautsprecherboxen mit Umschaltern an einzelnen Weichenzweigen, meist im Mittel- und/oder Hochtonzweig, sind bekannt. Sie erlauben Pegelangleichungen an die Raumakustik und/oder geschmackliche Entzerrungen. Es sind auch Boxen, die von aktiven Netzwerken angesteuert werden bekannt, die zusätzliche passive, festinstallierte Fre­ quenzweichen enthalten und so "Passivbetrieb" ermögli­ chen. Der Erfindung lag die Aufgabe zu grunde, die Frequenzweiche einer Lautsprecherbox so auszustatten, daß eine Änderung des Gesamtcharakters der Lautsprecherbox zur Anpassung an unterschiedliche Marktgewohnheiten und/oder individuelle Kundengeschmacksrichtungen vorge­ nommen werden kann. Passive loudspeakers with switches on individual ones Turnout branches, mostly in the middle and / or tweeter branch, are known. They allow level adjustments to the Room acoustics and / or taste equalization. There are also boxes that are controlled by active networks known, the additional passive, permanently installed Fre contain crossovers and thus "passive operation" possible chen. The invention was based on the object To equip the crossover of a loudspeaker so that a change in the overall character of the speaker to adapt to different market habits and / or individual customer tastes can be taken.

Die Lösung sieht vor, daß die Frequenzweiche als Mehrfachfrequenzweiche ausgebildet ist, deren sämtliche unterschiedliche Weichenzweige mittels eines zentral gesteuerten mehrpoligen Umschalters (S) wahlweise alter­ nativ an die Bereichs-Lautsprecher (TT, MHT) anschießbar sind, wobei für jeden Weichenzweig jeweils zwei korres­ pondierende Umschalterkontakte in zwei verschiedenen Schalterebenen (A, B) vorgesehen sind und diese paarweise abwechselnd geschlossen werden. The solution provides that the crossover as Multiple crossover is formed, all of them different switch branches by means of a central controlled multi-pole switch (S) optionally older can be connected natively to the range speakers (TT, MHT) are, with two corres for each branch bonding switch contacts in two different Switch levels (A, B) are provided and these in pairs be closed alternately.

Mehrfach-Frequenzweichen, passiver Art, für Lautsprecher­ boxen. Multiple crossovers, passive type, for loudspeakers boxing.
