1

Remove approximately 10 mm (3/8 in) of 

insulation from the end of each speaker 

cable and twist the exposed wires of the 

cable together to prevent short circuits.

2

Unscrew the knob.

3

Insert one bare wire into the hole in the side 

of each terminal.

4

Tighten the knob to secure the wire.

■

Connecting the banana plug

(U.S.A., Canada, Australia and General 

models only)

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.

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.

Left

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.
