To patch the signal to additional amplifiers, use the parallel input switches described on page 10.

Pour amener le signal vers d'autres amplificateurs, suivez les instructions de la page 10.

Um das Eingangs-signal weiteren Verstärkern zur Verfügung zu stellen, verwenden Sie die Parallel Input Schalter wie auf Seite 10 beschrieben.

Para pasar la señal a los amplificadores adicionales utilice el selector de entrada paralela descrito en la página 10.
