Unpacking
Unpack the unit carefully and make sure that all accessories
are put aside so they will not be lost.
Examine the unit for any possibility of shipping damage. If your unit
is damaged or fails to operate, notify your dealer immediately. If
your unit was shipped to you directly, notify the shipping company
without delay. Only the consignee (the person or company receiving the unit) can file a claim against the carrier for shipping damage.

7 Notes on heat generation
• This unit incorporates a ventilation fan to process heat generated during operation. As the fan
starts to rotate automatically when the internal temperature of this unit rises, avoid installing or
setting which may prevent ventilation of the unit.
* Leave clearance of more than 10 cm (4 in.) to the left and right, more than 50 cm (20 in.) above and
more than 10 cm (4 in.) in front and rear of the unit. Also, do not close the surroundings of the unit
tightly when it is mounted on a rack.
• The ventilation fan of this unit has been designed to intake external air into the unit. If curtain or a
piece of paper is attracted by the air intake, the internal temperature will rise and protection circuitry will be activated. In this case, the sound will not be output.
More than
50 cm (20 in.)
More than
10 cm (4 in.)
More than
10 cm (4 in.)
More than
10 cm (4 in.)
Standby mode
While the standby indicator is lit, a small amount of power is supplied to the system to back up the
memory. This is called standby mode. Under the condition, the system can be turned ON by the
remote control unit.
More than
10 cm (4 in.)
Make connection as shown below. When connecting the related system components, refer also to
the instruction manuals of the related components. Do not plug in the power lead until all connections are completed.
7 Connections of speaker cords
Connections of speaker cords
1 Strip coating. 2 Loosen. 3 Insert. 4 Secure.
Connection of banana plugs (Except for some countries, like
Singapore, etc.)
1 Secure. 2 Insert.
• Sound will not be heard if the speaker terminal is not fully secured.
CAUTION:
If the unit is used in the U.S.A. or Canada, please read the supplement to the operating instruction entitled “Connection of speaker cords”.
Warning!
Particular attention must be given to making good electrical contact at the amplifier-output and
speaker terminals.
Poor or loose connections can cause sparking or burning at the terminals because of the very
high power that the amplifier can deliver.
CAUTIONS:
• Connect all cords firmly. If connections are loose, there could be loss of sound or noise produced.
• Never attempt to connect two or more speaker cords to a single speaker terminal.
• Never short-circuit the + and - speaker cords.
• If the left and right speakers are connected inversely or if the speaker cords are connected with
reversed polarity, the sound becomes unnatural with ambiguous acoustic image positioning.
Be sure to connect the speakers and speaker cords correctly.
