Abstract

Es wird eine Beschallungsvorrichtung mit vier Lautsprechern (1, 2) und einer mindestens zwei Lautsprechern (1, 2) vorgeschalteten, durch zwei Eingangssignale (E1, E2) angesteuerten Sinalaufbereitungseinrichtung (5) zum Erzeugen von Ansteuersignalen (A1, A2) für die Lautsprecher (1, 2) vorgestellt. Die Ansteuersignale (A1, A2) sind dabei jeweils gleich der Summe über die in Amplitude und Phase jeweils unterschiedlich bewerteten Eingangssignale (E1, E2) derart, daß die Abstrahlcharakteristik der beiden Lautsprecher (1, 2) von der Bewertung der Eingangssignale (E1, E2) abhängt.
