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 a 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.
S002*_A1_En
If the AC plug of this unit does not match the AC
outlet you want to use, the plug must be removed
and appropriate one fitted. Replacement and
mounting of an AC plug on the power supply cord of
this unit should be performed only by qualified
service personnel. If connected to an AC outlet, the
cut-off plug can
cause severe electrical shock. Make
sure it is properly disposed of after removal.
The equipment should be disconnected by removing
the mains plug from the wall socket when left unused
for a long period of time (for example, when on
vacation).
D3-4-2-2-1a_A1_En
CAUTION
The STANDBY/ON switch on this unit will not
completely shut off all power from the AC outlet.
Since the power cord serves as the main disconnect
device for the unit, you will need to unplug it from the
AC outlet to shut down all power. Therefore, make
sure the unit has been installed so that the power
cord can be easily unplugged from the AC outlet in
case of an accident. To avoid fire hazard, the power
cord should also be unplugged from the AC outlet
when left unused for
a long period of time (for
example, when on vacation).
D3-4-2-2-2a*_A1_En
VENTILATION CAUTION
When installing this unit, make sure to leave space
around the unit for ventilation to improve heat radiation
(at least 40 cm at top, 10 cm at rear, and 20 cm at each
side).
WARNING
Slots and openings in the cabinet are provided for
ventilation to ensure reliable operation of the product,
and to protect it from overheating. To prevent fire
hazard, the openings should never be blocked or
covered with items (such as newspapers, table-cloths,
curtains) or by operating the equipment on thick carpet
or a bed.

What’s in the box
Please confirm that the following accessories are in the
box when you open it.
•Remote control
• AAA/IEC R03 dry cell batteries x2
• AM loop antenna
• FM wire antenna
•Power cord
• Warranty card
• Quick start guide
• Safety Brochure
• These operating instructions (CD-ROM)
Note
• Illustrations featured in the Operating Instructions
may have been modified or simplified for ease of
explanation, and may therefore differ from the
actual product appearance.
• The illustrations used here are mainly of the SX-20S (Silver) model.
Loading the batteries in the remote
control
1 Open the rear lid.
4
En
2 Insert the new batteries, matching the
polarities as indicated inside the case.
3 Close the rear lid.
The batteries included with the unit have been provided
to allow you check product operation and may not last
long. We recommend using alkaline batteries that have
a longer life.
WARNING
• Do not use or store batteries in direct sunlight or
other excessively hot place, such as inside a car or
near a heater. This can cause batteries to leak,
overheat, explode or catch fire. It can also reduce
the life or performance of batteries.
CAUTION
Incorrect use of batteries may result in such hazards as
leakage and bursting. Observe the following
precautions:
• When inserting the batteries, make sure not to
damage the springs on the battery’s terminals.
This can cause batteries to leak or overheat.
• Do not use any batteries other than the ones
specified. Also, do not use a new battery together
with an old one.
• When loading the batteries into the remote control,
set them in the proper direction, as indicated by the
polarity marks ( and ).
• Do not heat batteries, disassemble them, or throw
them into flames or water.
• Batteries may have different voltages, even if they
are the same size and shape. Do not use different
types of batteries together.
• To prevent leakage of battery fluid, remove the
batteries if you do not plan to use the remote
control for a long period of time (1 month or more).
If the fluid should leak, wipe it carefully off the
inside of the case, then insert new batteries. If a
battery should leak and the fluid should get on your
skin, flush it off with large quantities of water.
• When disposing of used batteries, please comply
with governmental regulations or environmental
public institution’s rules that apply in your country/
area.
Using the remote control
The remote has a range of about 7 m at an angle of about
30º from the remote sensor.
Keep in mind the following when using the remote
control:
• Make sure that there are no obstacles between the
remote and the remote sensor on the unit.
• Remote operation may become unreliable if strong
sunlight or fluorescent light is shining on the unit’s
remote sensor.
• Remote controllers for different devices can
interfere with each other. Avoid using remotes for
other equipment located close to this unit.
• Replace the batteries when you notice a fall off in
the operating range of the remote.
Installing the receiver
When installing this unit, make sure to put it on a level
and stable surface.
• Don’t install it on the following places:
– on a color TV (the screen may distort)
– near a cassette deck (or close to a device that
gives off a magnetic field). This may interfere with
the sound.
– in direct sunlight
– in damp or wet areas
– in extremely hot or cold areas
– in places where there is vibration or other
movement
– in places that are very dusty
– in places that have hot fumes or oils (such as a
kitchen)
• Do not mount the unit on a sofa or other object or
material with absorbent qualities, since sound
quality may be adversely affected.

Connecting up
Making cable connections
CAUTION
• Before making or changing the connections, switch off the power and disconnect the power cord from the AC
outlet.
• Connect the power cord after all the connections between devices have been completed.
Important
•The SIGNAL GND terminal is provided to reduce
noise when connecting the unit to components
such as an analog turntable.
• Do not connect the PHONO (MM) terminals to any
component other than a turntable; also, do not
connect to a turntable equipped with built-in
equalizer. An excessively high sound output may be
produced, resulting in damage to your speakers or
other devices.
• The unit’s PHONO (MM) terminals are designed to
be used with turntables equipped with MM
(moving-magnet) type cartridges. Turntables
equipped with MC (moving-coil) cartridges cannot
be used.
• Make sure not to bend the cables over the top of
this unit (as shown in the illustration). If this
happens, the magnetic field produced by the
transformers in this unit may cause a humming
noise from the speakers.
• If your turntable has a grounding wire, secure it to
the ground terminal on this receiver.
Note
• When connecting a tape cassette deck, playback
noise may be heard, depending on the installation
location. This noise is caused by leakage flux from
the receiver’s transformer. In this event, change the
installation location, or move the deck farther from
the receiver.
Connecting audio cables
Connect the white plug to the left (L) jack, and the red
plug to the right (R) jack. Be sure to insert the plugs fully
into the jacks.
Connecting speaker cables
1 Twist the cable cores.
2 Loosen the nut on the
SPEAKERS
terminal, and insert the speaker cable into
the exposed hole in the terminal shaft.
3 Retighten the terminal nut.
12 3
CAUTION
• When using only one set of speaker terminals
(SPEAKERS A or SPEAKERS B), the speaker used
should have a nominal impedance between 4 Ω
and 16 Ω. When using both sets of terminals,
the connected speakers should have nominal
impedance between 8 Ω and 16 Ω. Consult the
instructions accompanying your speakers for
details regarding the impedance value.
• Make sure the positive and negative (+/–) terminals
on the receiver match those on the speakers.
• These speaker terminals carry HAZARDOUS live
voltage. To prevent the risk of electric shock when
connecting or disconnecting the speaker cables,
disconnect the power cord before touching any
uninsulated parts.
• Make sure that all the bare speaker wire is twisted
together and inserted fully into the speaker
terminal. If any of the bare speaker wire touches the
back panel it may cause the power to cut off as a
safety measure.
