Mono-Abgriff aus Stereo-Signal

Beitragvon Tim Sasdrich » 17.04.2013, 11:18

Hallo,

ich möchte gerne die LED-Lichtorgel an meine Anlage anschließen (Line-In-Signal). Ich möchte aber nicht, dass sie nur auf einem der beiden Kanäle (Rechts/Links) arbeitet, sondern dass sie auf Signale von beiden Kanälen reagiert. Aber wenn ich die beiden Kanäle einfach zusammenschließe, kommt aus den Lautsprechern nur noch ein Mono-Signal, zudem weiß ich nicht, wie sehr das die Signalquelle verkraftet.

Masse beider Kanäle ist verbunden. Und wenn es ein leichtes übersprechen zwischen Rechts und Links gibt, ist das ok. Es sollte eben noch als Stereo erkennbar sein.

Irgendwo habe ich hier mal eine einfache Lösung gesehen. Wenn ich mich richtig erinnere, waren es zwei 47 kΩ? Widerstände in Reihe zwischen dem rechten und linken Signal, der Mittelabgriff davon ging auf die Schaltung. Ich weiß aber nicht, ob es nur für den Lautsprecherausgang oder auch für ein Line-In-Signal geeignet ist.

Eine einfache Lösung mit wenigen Bauteilen wäre toll.

Monomatrix ist der richtige Suchbegriff :wink:

Vielen Dank, das ist genau, was ich gesucht habe. Da hatte ich wohl die falschen Suchbegriffe verwendet.
