However, the stored data will be lost if the power cord is disconnected from the AC wall outlet for more than one week. ■ AC OUTLET(S) (SWITCHED) Australia model 1 outlet Other models 2 outlets Use these outlets to connect the power supply cords from your other components to this unit. The AC OUTLET(S) supplies power to any connected components whenever the power of this unit is turned on. For information on the maximum power (total power consumption of components), see "SPECIFICATIONS" on page 30. ■ REMOTE jacks Some YAMAHA models are able to connect directly to the REMOTE jack on the rear panel of this unit. If you own these products, you may not need to use an infrared emitter. Up to six YAMAHA components can be connected as shown below. CONNECTIONS ■ VOLTAGE SELECTOR (Asia and General models only) VOLTAGE SELECTOR on the rear panel of this unit must be set for your local main voltage BEFORE plugging the power supply cord into the AC wall outlet. Voltages are as follows: Asia model AC 220/230-240 V, 50/60 Hz General model ...... AC 110/120/220/230-240 V, 50/60 Hz ■ IMPEDANCE SELECTOR switch CAUTION Do not slide the IMPEDANCE SELECTOR switch while the power of this unit is turned on, as doing so may damage the unit. 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 separate 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.
