VOLTAGE SELECTOR SWITCH
Only multi-voltage model is provided with this switch.
U.K., European, Australian and New Zealand models are
not provided with this switch.
Main voltages in Saudi Arabia are 127 V and 220 V only.
Never use this model with 110 V setting in Saudi Arabia.
The line voltage selector switch is on the rear panel. Check
that it is set properly before plugging the power cord into the
AC outlet. If the voltage is not properly set or if you move to
an area where the voltage requirements differ, adjust the
selector switch as follows.
1. Disconnect the power cord.
2. Use medium-size screwdriver.
3. Insert the screwdriver into the groove on the voltage
selector and adjust so that the tip of the arrow points to the
voltage value of your area.
220V
110V
120-127V240V
Information to User
Alteration or modifications carried out without appropri-
ate authorization may invalidate the user's right to oper-
ate the equipment.
POWER-CORD CAUTION
Handle the power cord by the plug. Do not pull out the plug by
tugging the cord and never touch the power cord when your
hands are wet as this could cause a short circuit or electric
shock. Do not place the unit, a piece of furniture, etc., on the
power cord, or pinch the cord. Never make a knot in the cord
or tie it with other cords. The power cords should be routed
such that they are not likely to be stepped on. A damaged
power cord can cause fire or give you an electrical shock.
Check the power cord once in a while. When you find it
damaged, ask your nearest PIONEER authorized service
center or your dealer for a replacement.
MAINTENANCE OF EXTERNAL SURFACES
÷Use a polishing cloth or dry cloth to wipe off dust and
dirt.
÷When the surfaces are very dirty, wipe with a soft cloth
dipped in some neutral cleanser diluted five or six times
with water, and wrung out well, and then wipe again
with a dry cloth. Do not use furniture wax or cleaners.
÷Never use thinners, benzine, insecticide sprays or other
chemicals on or near this unit, since these will corrode
the surfaces.

CONTENTS
FEATURES
7 High-power Output of 40W+40W/8-„¦(DIN)
7 Wide-Range Linear Circuit
This new current feedback circuit assures improved oper-
ating stability for flat output impedance and stable driving
of speakers across the full range of frequencies.
7 Low power consumption design.
7 Complementary capacitor pair.
7 Direct Energy MOS Power Amp
Pioneer introduces amp circuitry featuring HEX power
MOS FET devices for high performance. Together with
Pioneer's original Wide Range Linear Circuit technology,
this helps achieve reducing power consumption, while
maintaining the power of current models.
In terms of performance, it contributes to flat damping
factor characteristics across the audio spectrum, and im-
proved power linearity.
INSTALLATION
LOCATION
Install the unit in a well-ventilated location where it
will not be exposed to high temperatures or humid-
ity.
Do not install the unit in a location which is exposed to direct
rays of the sun, or near hot appliances or radiators. Excessive
heat can adversely affect the cabinet and internal compo-
nents. Installation of the unit in a damp or dusty environment
may also result in a malfunction or an accident. (Avoid
installation near cookers etc., where the unit may be exposed
to oily smoke, steam or heat.)
Do not install the unit on a tottered stand, nor on an unstable
or inclined surface.
VENTILATION
÷When installing this unit, make sure to leave space around
the unit for ventilation to improve heat radiation (at least 60
cm at top, 10 cm at rear, and 30 cm at each side). If not
enough space is provided between the unit and walls or
other equipment, heat will build up inside, interfering with
performance or causing malfunctions.
÷Do not place on a thick carpet, bed, sofa or fabric having a
thick pile. Do not cover with fabric or other covering.
Anything that blocks ventilation will cause internal tem-
perature to rise, which may lead to breakdown or fire
hazard.
