Yamaha RX-497 User Manual

■ Connecting the banana plug

First, tighten the knob and then insert the banana plug into 
the end of the corresponding terminal.

• One or two speaker sets can be connected to this unit. If you use 

only one speaker set, connect it to either the SPEAKERS A or B 
terminals.

• Use speakers with the specified impedance shown on the rear 

panel of this unit.

■ IMPEDANCE SELECTOR

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 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.

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.
