If this is the case, slide the switch all the way to either position when this unit's power supply is completely cut off. Select the switch position (LOW or HIGH) according to the impedance of the speakers in your system. Switch position HIGH LOW Impedance level • If you use one set (A or B), the impedance of the speaker must be 6 Ω or higher. • If you use two sets (A and B) simultaneously, the impedance of each speaker must be 12 Ω or higher. (Except for U.S.A and Canada models) • If you make bi-wire connections, the impedance of the speaker must be 6 Ω or higher. See page 7 for details. • If you use one set (A or B), the impedance of the speaker must be 4 Ω or higher. • If you use two sets (A and B) simultaneously, the impedance of each speaker must be 8 Ω or higher. • If you make bi-wire connections, the impedance of the speaker must be 4 Ω or higher.
