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.  
Connections____________________________  
Connection precautions  
When connecting, either disconnect the power plug from the  
power outlet or turn off the units 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.  
Precautions____________________________  
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.  
Turntable  
Connect the turntables output cord L (white) plug to the L  
PHONO terminal and the R (red) plug to the R terminal.  
If your turntable is equipped with a grounding cable, connect it to  
the units GND terminal. But disconnect it if you notice increased  
hum.  
-
If you use the turntable alongside the unit, hum and noise  
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.  
pickup may sometimes. In such a case, install the turntable at a  
position where hum and noise are not picked up.  
Compact disc player  
Connect the CD terminals to the OUTPUT terminals on the  
compact disc player using the pin-plug cord.  
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 and may lead to failure  
or malfunction.  
Tuner  
Connect the TUNER terminals to the OUTPUT terminals on the  
tuner using the pin-plug cord.  
DVD Terminal  
Connect the DVD terminals to the OUTPUT terminals on the DVD  
player 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.  
Playback connections: Connect the TAPE PLAY terminals to  
the output (LINE OUT) terminals on the cassette deck using the  
pin-plug cord.  
Installation precautions  
Do not install the unit in any of the following locations since this  
may result in deterioration in performance or 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.  
Equalizer 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.  
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.  
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.  
Speaker systems  
Do not use insecticide sprays in the vicinity.  
Connect the speaker systems to the SPEAKERS terminals on the  
rear panel of the unit with the speaker cords. Two sets of speaker  
systems can be connected, one to front (Main) speakers and one  
to rear speakers (Surround) in order to achieve the surround  
sound effect.  
This unit dissipates the heat most effectively when installed on  
a flat surface. Do not stand it up or install it at an angle.  
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.  
Before connecting the power plug  
Before connecting the power plug to an electrical outlet, check to  
be sure that the unit is set to the power voltage for your area. If  
the voltage of the unit is improperly set, fire hazard or damage to  
the unit may result. If you find that the unit is not set to the proper  
voltage for your area follow the instructions listed below.  
- Unit without voltage selectors switch.  
- Unit destined for some areas are not fitted with a voltage  
selector switch due to laws and regulations existing in those  
areas. In such a case, the power supply voltage is set to the  
voltage used in the area where the unit is purchased.  
When connecting, do not allow the conductor of the speaker  
cords to be exposed from the terminals and come into contact  
with other terminals.
