PRECAUTIONS
Thank you for purchasing this HI-FI product. Taking time
to read these operating instructions carefully before use
will acquaint you fully with all its features and help ensure
optimum performance.
In order to simplify the explanation illustrations may
sometimes differ from the originals.
RISK OF ELECTRIC SHOCK
DO NOT O PEN
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER(OR BACK)
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
The lighting flash with arrowhead symbol,
within an equilateral, is intended to alert the user
to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may
be of sufficient magnitude to constitute a risk of
Do not remove the case and bottom panel
Any inspections or adjustments inside the unit
may lead to malfunctions and electric shocks.
Do not touch any of the inside parts.
Do not block the ventilation holes
Do not block the ventilation holes on the top of
the unit by placing records or other objects over
them. This will increase the inside temperature
may lead to a failure or malfunction.
Installation precautions
Do not install the unit in any of the following
electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and maintenance
(servicing) instructions in the literature
accompanying the appliance.
WARMING: To prevent fire or shock hazard, do not
expose this appliance to rain or moisture
Power plug
When disconnecting the power cord from the
power outlet, always take hold of the plug, and
not the wire, and pull free. Never connect or
disconnect the power plug with wet hands since
you may receive an electric shock.
Remember to disconnect the power plug from
the power outlet when you do not intend to use
the unit for a prolonged period of time.
locations since this may result in deterioration
in performance of malfunction:
* Locations exposed to direct sunlight or near objects
radiating heat such as heating appliances.
* Locations exposed to moisture or humidity.
* Locations with poor ventilation exposed to dust and
dirt.
* Locations which are unstable and not perfectly flat or
which are susceptible to vibration.
Do not wipe with thinners
Wipe the panels and case from time to time
with a soft cloth. Using any kind of thinner,
alcohol or volatile liquid will mar the surface,
cause blotching on the exterior and erase the
markings and should therefore be avoided. Do
not use insecticide sprays in the vicinity.

CONNECTIONS FOR INTEGRATED STEREO AMPLIFIER
Refer to page 4 the connection diagram as you read the following.
Connection precautions
When connecting, either disconnect the power plug
from the power outlet or turn off the unit’s power
using the POWER switch.
Check the left and right channels and connect properly
(Left to L and Right to R).
Insert the plugs securely. Improper connection can lead
to the generation of noise.
Compact disc player
Connect the CD terminals to the OUTPUT terminals on the
compact disc player using the pin-plug cord.

PROCESSOR terminals
These terminals are used to connect a graphic equalizer or
sound processor. They also come in handy for connecting
an AV (audio/video) selector unit.
CD/AUX terminals
These terminals have an electrical performance which is
equivalent to that of the CD terminals and the TUNER
terminals which means that they can be used as the audio
output terminals for a video disc player or TV tuner.
Connect these terminals to the OUTPUT terminals on the
component using the pin-plug cord.
TAPE Deck
Recording connections: Connect the TAPE REC
terminals to the input (LINE IN) terminals on the tape deck
using the pin-plug cord.
Use pin-plug cords to connect the REC terminals to the
INPUT terminals on the selected component and also to
connect the PLAY terminals to its OUTPUT terminals.

CONNECTIONS
Speaker systems
Connect the speaker systems to the SPEAKERS terminals
on the rear panel of the unit with the speaker cords.
When viewed from the front (the listening position), the
speaker mounted on the left should be connected to the L
terminals, and the speaker mounted on the right should be
connected to the R terminals. Be sure to connect the
polarities of the speaker systems and the SPEAKER
terminals correctly (+ to +, - to -). If the polarity of one of
the speaker systems is connected improperly, sound in the
central area between the speakers will appear to be missing,
and the position of the instruments will not be clear,
resulting in a loss of stereo directionality; so take care
when connecting.
* When connecting, do not allow the conductor of the
speaker cords to be exposed from the terminals and come
into contact with other terminals.
Tuner
Connect the TUNER terminals to the OUTPUT terminals
on the tuner using the pin-plug cord.
