CONNECTIONS CONNECTING SPEAKERS Connect the SPEAKERS terminals to your speakers with wire of the proper gauge (cut as short as possible). If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and - markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass. Do not let the bare speaker wires touch each other or the metal parts of this unit as this could damage this unit and/or speakers.

CONNECTING SPEAKERS
Connect the
SPEAKERS
terminals to your speakers with
wire of the proper gauge (cut as short as possible). If the
connections are faulty, no sound will be heard from the
speakers. Make sure that the polarity of the speaker wires is
correct, that is, + and – markings are observed. If these
wires are reversed, the sound will be unnatural and will lack
bass.
Do not let the bare speaker wires touch each other or the
metal parts of this unit as this could damage this unit
and/or speakers.
1
Unscrew the knob.
2
Insert the bare wire.
[Remove approx. 5mm (1/
4”) insulation from the
speaker wires.]
3
Tighten the knob and
secure the wire.
Notes
•
One or two speaker systems can be connected to this unit. If you
connect only one speaker system, connect it to either the
SPEAKERS A
or
B
terminals.
•
Use speakers with the specified impedance shown on the rear of
this unit.
•
Banana Plug connections are also possible. Simply insert the
Banana Plug connector into the corresponding terminal.

IMPEDANCE SELECTOR switch
WARNING
Do not change the IMPEDANCE SELECTOR
switch setting while the power to this unit is on,
otherwise this unit may be damaged.
If this unit fails to turn on when the
POWER
switch is
pressed:
The
IMPEDANCE SELECTOR
switch may not be set
to either end. If so, set the switch to either end when this
unit’s power supply is completely cut off.
(Left position)
If you use one pair of speakers, the impedance of each
speaker must be 4
Ω
or higher.
If you use two pairs of speakers, the impedance of each
speaker must be 8
Ω
or higher.
(Right position)
<U.S.A. and Australia models>
If you use one pair of speakers, the impedance of each
speaker must be 6
Ω
or higher.
If you use two pairs of speakers, the impedance of each
speaker must be 12
Ω
or higher.
<Canada model only>
The impedance of each speaker must be
6
Ω
or higher.
