•Fase destra dell'interruttore posizionata su 180° per l'operazione stereo/ mono

•Tutta la polaritá dell'altoparlante del canale destro é invertita per correggere il segnale di fase

•Gain per i canali destro e sinistro posizionati ugualmente per bilanciare i subwoofer

•Impedenza per ogni canale deve essere minimo 2Ω

•Impedenza per i canali a ponte deve essere minimo 4Ω
