Important Safety Information
CAUTION! PLEASE READ THE INSTRUCTIONS BEFORE CONNECTING YOUR LOUDSPEAKERS
When making any connections, always disconnect all system
components from the mains.
To reduce risk of electric shock, do not expose the loudspeakers
to rain or moisture.
Do not remove the unit cover or back. There are no user
serviceable parts inside.
Unplug the sub woofer from the mains before cleaning. Do not
use liquid or aerosol cleaners. Use only a damp cloth.
Ensure all the loudspeakers are mounted on a solid stand or wall
bracket specially designed for this application. If in doubt
consult your dealer.
Ensure that there is adequate space for ventilation around the
sub-woofer amplifier panel.
Do not dispose of the packing materials for your loudspeakers as
you may wish to transport them at some future date. Correct
packing will ensure that they can be shipped safely.
Hitachi loudspeakers are compliant to EN60065 and bear the CE
mark.
Positioning your loudspeakers
Place the loudspeakers as shown in diagram 1. The front
satellites should be placed at ear level, while the rear satellites
should be placed 0.5m higher. The centre channel may be placed
on top of the television or on a shelf in the console below. If the
centre channel is placed on top of the television, ensure that the
television cabinet can stand the weight. If in doubt consult your
dealer.
The position of the subwoofer will affect the level of bass
response. For increased bass place the subwoofer against a wall
or in a corner. (See diagram 1)
Connections and Phasing
Satellites and Centre Channel
Ensure that you use two-core polarity coded cable designed for
loudspeaker use.

Possible Cause
3
Carefully split the cable to a depth of 30mm. Strip 10mm of
insulation from each wire exposing the metal conductor. If the
cable is stranded twist the strands to form a single wire. Push in
the connector on the loudspeaker and insert the bare conductor
wire into the hole and release the connector.
Connect the red, positive (+) terminal of the right loudspeaker to
the red (+) terminal of the amplifier. Connect the Black (-)
connectors in a similar way. Repeat for other loudspeakers.
It is important to connect your speakers correctly. Should you
inadvertently connect the red (+) to the black (-) your speakers
will be out of phase and will result in a thin and poorly focused
sound.
Sub-woofer
When connecting your sub-woofer to the mains supply ensure
that the power switch is in the off position. Do not switch on the
power until all connections are made. The diagram on Page 2
illustrates how to connect the sub-woofer to the AV receiver.
Please observe the polarity of your AV processor and sub-
woofer terminals.
Please ensure that the subwoofer is placed a minimum of
0.5metres away from any magnetically sensitive device such as
a TV receiver.
Setting up your AV Loudspeakers
Sub-woofer
For the initial set-up, set the Freq. and volume control to the mid
way position. Set the AV receiver to stereo mode and play
music with a broad band of frequencies. Adjust the volume
control on the sub-woofer until the bass effect is apparent
without drawing attention to the sub woofer.
After adjusting the sub woofer, switch your AV receiver to
surround sound and continue the setup as per your AV Receiver
instruction manual.
Procedures
Check the cables have been connected as shown in the
instructions
Switch the system and adjust the volume
Check cable connections/change polarity
Check cable connections /change polarity
Place woofer and satellites further away from the walls
(approx. 80 cm clearance)
Set the bass to neutral position
Turn volume down
Please contact your dealer or HITACHI Service Centre
Correct cable connections
Check whether all speakers have been correctly connected up
