Yamaha RX-397 Manuale Utente

Plug the power supply cord into the AC wall outlet after 
all other connections are complete.

■ 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.

■ VOLTAGE SELECTOR

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

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.

• 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.

Memory back-up
The memory back-up circuit prevents the stored data 
from being lost. However, the stored data will be lost if 
the power cord is disconnected from the AC wall outlet 
for more than one week.

Ω

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.

If you use two sets (A and B), the impedance 
of each speaker must be 8 

Ω

 or higher.
