Abstract

The device has inputs for at least two receivers and the same number of network inputs wired to receiver network outputs. The voltage is polled for at least one of the network inputs and evaluated so that the boxes that are associated with this input are switched to active. At least one network input also has an associated manual switch.

Description

Stand der Technik der Unterhaltungselektronik sind zwei wesent­ liche Arten der Musikwiedergabe: Einmal die Stereo-Wiedergabe: Von einem Receiver (1) gehen zwei Ausgänge zu jeweils einer Box (3). Zum anderen die Surround-Wiedergabe. Der Receiver (2) hat mindestens fünf Ausgänge zu fünf Boxen, und zwar ein­ mal zum "Center" (5), dann zu den beiden Frontboxen (3), die in dieselbe Position zum Hörer gestellt werden wie die beiden Boxen (3) der Stereo-Wiedergabe. Dann zu den beiden Rear- Boxen (4), die hinter den Hörer gestellt werden.State of the art in consumer electronics are two main types of music playback: First, stereo playback: Two outputs go from a receiver ( 1 ) to a box ( 3 ). On the other hand, surround playback. The receiver ( 2 ) has at least five outputs to five boxes, once to the "center" ( 5 ), then to the two front boxes ( 3 ), which are placed in the same position as the listener as the two boxes ( 3 ) stereo playback. Then to the two rear boxes ( 4 ), which are placed behind the receiver.

Obwohl die beiden Front-Boxen (3) der Surround-Wiedergabe den beiden Boxen der Stereo-Wiedergabe (3) entsprechen, können sie nicht ohne weiteres zugleich vor einer Stereo-Receiver (1) und von einer Surround-Receiver (2) angesteuert werden. Viel­ mehr ist dazu ein Umschaltgerät (6) notwendig.Although the two front boxes ( 3 ) for surround playback correspond to the two boxes for stereo playback ( 3 ), they cannot easily be controlled at the same time in front of a stereo receiver ( 1 ) and a surround receiver ( 2 ) , A switching device ( 6 ) is much more necessary for this.

Nach dem Stand der Technik wird dieses Umschaltgerät (6) ma­ nuell betrieben: Je nachdem der Hörer stereo oder surround hören will, muß er das Umschaltgerät entsprechend bedienen, beispielsweise einen Kippschalter umlegen. Dieser Stand der Technik hat eine Reihe von Nachteilen:
Vergißt man, daß die Anlage auf stereo geschaltet ist und hört man surround, dann sind nur die Lautsprecher aktiv, die fest verdrahtet sind, also der Center (5), die beiden Rear-Boxen (4) und, sofern vorhanden, die weiteren Boxen der Surround- Anlage, beispielsweise ein oder mehrere Subwoofer (7). According to the prior art, this switching device ( 6 ) is operated manually: depending on the listener who wants to hear stereo or surround, he must operate the switching device accordingly, for example flip a toggle switch. This prior art has a number of disadvantages:
If you forget that the system is switched to stereo and you hear surround, then only the loudspeakers are active that are hard-wired, i.e. the center ( 5 ), the two rear boxes ( 4 ) and, if available, the other boxes the surround system, for example one or more subwoofers ( 7 ).

Die Front-Boxen (3) sind nicht aktiv, was der Hörer beispiels­ weise bei Monologen, die nur über den Center (5) hörbar ge­ macht werden, nicht sofort bemerken muß. Endet im Beispiels­ fall der Monolog, dann sind die Front-Boxen nicht hörbar und der Surround-Effekt fehlt. Bei Sendungen, die surround aus­ gestrahlt werden, führt dies zu unwiederbringlichen Hörver­ lusten.The front boxes ( 3 ) are not active, which the listener does not immediately notice, for example, with monologues that are only made audible via the center ( 5 ). If the monologue ends in the example, the front boxes are not audible and the surround effect is missing. For programs that are broadcast in surround, this leads to irreparable hearing losses.

Wird von einem Tonträger abgespielt, dann hat der Stand der Technik ebenfalls Nachteile: Zwar ist der Hörverlust nicht un­ wiederbringlich. Um den Tonträger vollständig in der Surround- Wiedergabe abzuhören, muß dann aber neu gestartet werden.If you are playing from a sound carrier, then the status is Technology also has disadvantages: hearing loss is not uncommon again brin possible. In order to completely surround the sound carrier Listen to playback, but must then be restarted.

Diesen Nachteil vermeidet die Erfindung:
Das Umschaltgerät fragt selbständig ab, ob am Netzeingang, der mit dem Netzausgang des Surround-Receivers verbunden ist, Spannung anliegt. Ist dies der Fall, dann wird - beispielsweise mittels eines Relais das Umschaltgerät auf den Surround-Betrieb umgestellt mit der Folge, daß sämtliche Surround-Boxen aktiv sind. Liegt am Surround-Netz-Eingang keine Spannung an, dann sind nur die beiden Front-Boxen aktiv.The invention avoids this disadvantage:
The switching device automatically queries whether there is voltage at the mains input that is connected to the mains output of the surround receiver. If this is the case, the changeover device is switched to surround mode, for example by means of a relay, with the result that all surround boxes are active. If there is no voltage at the surround network input, only the two front boxes are active.

Vorteilhaft ist die Erfindung nicht nur dann, wenn die selben Front-Boxen wahlweise bei der Stereo- und der Surround-Wieder­ gabe aktiv sind sondern auch dann, wenn wahlweise zwei Stereo-Receiver benutzt werden sollen, wie es dann der Fall ist, wenn jeder der beiden Receiver besonders klangliche Merkmale hat, die der Hörer für die jeweilige Wiedergabe be­ vorzugt. In diesem Fall werden die beiden Boxen-Ausgänge des zweiten Stereo-Receivers in die Front-Boxen-Buchsen des Surround-Eingangs gesteckt und das erfindungsgemäße Umschalt­ gerät funktioniert auf gleiche Weise.The invention is advantageous not only when the same Front boxes optionally with the stereo and the surround again are active but also if two are available Stereo receivers are to be used, as is the case then is when each of the two receivers is particularly sonic Has features that the listener be for the respective playback vorzugt. In this case, the two box outputs of the  second stereo receiver into the front speakers of the Surround input inserted and the switch according to the invention device works in the same way.
