•L'interrupteur “Right Phase” doit se trouver dans la position “180° ” pour operation en tri-mode

•Les gains des canaux gauche et droit sont réglés de la même manière pour équilibrer le subwoofer

•L'impédance de chaque canal devrait être de minimum 2Ω

•L'impédance du canal mono devrait être de minimum 4Ω

•Les XCards sont introduites sur fall range

•Il est conseillé d'utiliser les filtre passifs lorsqu'on fait fonctionner l'amplificateur en tri-mode

•NE connecter AUCUN des câbles HP à la masse au risque d'un fonctionnement instable.
