Select the switch position (left or right) according to the impedance of the speakers in your system. Switch position Impedance level Right If you use one set (A or B), the impedance of each speaker must be 8 Ω or higher. If you use two sets (A and B), the impedance of each speaker must be 16 Ω or higher. If you use one set (A or B), the impedance of each speaker must be 4 Ω or higher. Left If you use two sets (A and B), the impedance of each speaker must be 8 Ω or higher. Notes • The Canada model cannot use two speaker sets (A and B) simultaneously when the IMPEDANCE SELECTOR switch is slid to the right position. • If this unit fails to turn on, the IMPEDANCE SELECTOR switch may not be fully slid to either position. If this is the case, slide the switch all the way to either position when the power supply to this unit is completely cut off. 11
