Connect the SPEAKERS terminals to your speakers with wire
of the proper gauge, cut to be 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 and do
not let them touch the metal parts of this unit as this could
damage this unit and/or speakers.

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 terminals.

Use speakers with the specified impedance shown on the
rear of this unit.

How to Connect:

Red: positive (+)
Black: negative (–)

Press up the tab.

Insert the bare wire.
[Remove approx. 5mm
(1/4”) insulation from
the speaker wires.] 

Press down the tab and
secure the wire.

ABOUT THE ACCESSORY TERMINALS

AC OUTLETS

(U.S.A., Canada Europe and General models)

............................................................2 SWITCHED OUTLETS

(Australia and U.K. models)
...............................................................1 SWITCHED OUTLET
Use these to connect the power cords from your components
to this unit.
The power to the SWITCHED outlets is controlled by this unit’s
POWER switch or the provided remote control transmitter’s
POWER key.  These outlets will supply power to any
component whenever this unit is turned on.
The maximum power (total power consumption of
components) that can be connected to the SWITCHED AC
OUTLETS 
is 100 watts  (200 watts for U.S.A. and General
models).

GND terminal (For turntable use) 

Connecting the ground wire of the turntable to this terminal will
minimize hum, but in some cases better results may be
obtained with the ground wire disconnected.
