CONNECTIONS
Be sure to connect the left channel (L), right channel (R), “+” (red) and “–” (black) properly.
Before connecting the speakers, make sure that the power of this unit is off.
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 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.
