•Chinch Eingänge des rechten und linken Kanales anschlieβ en

•Signal Eingangsschalter auf “unbalanced” für den Betrieb mit Chinch-Kabel stellen

•Linken Phasen Schalter auf 0° stellen

•Rechten Phasen Schalter auf 180° stellen für den Stereo/Mono Betrieb

•Die Lautsprecher-Phase des rechten Kanales umkehren, um eine Phasenkorrektur zu erreichen

•Gain Regler des linken Kanales angleichen, um die Lautstärke des Subwoofers einzustellen

•Impendanz für jeden Kanal sollte minimum 2 Ohm betragen

•Impendanz im Brückenbetrieb sollte minimum 4 Ohm betragen

•XCard sollte auf Full Range gesteckt werder

•Passive Frequenzweichen werden für korrekte Stereo/Mono Operationen benötigt
