WH-DFS Loudspeaker Instruction Manual
INTRODUCTION
The WH-DFS speakers are bipolar units designed for use
solely as rear effects speakers.
In a Home Theatre system, the directional cues come from
the front and centre channels. The rear channels provide
ambience and rear perspective and for this purpose a
bipolar design with its mix of direct and reflected sound is
ideal.
Before installing your loudspeakers please read these
instructions in full.
CONNECTIONS
The WH-DFS speakers connect to the 'Rear' or 'Rear
Surround'terminals of your AV amplifier or processor.
You will need one length of twin core cable per speaker.
Connect the Red (+) terminal of the left rear unit to
the Red (+) terminal of the amplifier's left rear channel
output. Connect the Black (-) terminal of this unit to the
corresponding Black (-) terminal of the amplifier. Repeat
for the Right speaker. The connection panel uses screw
terminals - the drawing illustrates the connection.
UNPACKING
Carefully unpack each component taking care not to mark
the surface. Inspect the product and report any damage
immediately to your dealer. Retain the packing so that the
product may be safely shipped in the future.
IMPORTANT DO'S AND DON'TS
WARNING: To reduce the risk of fire or electrical shock
do not expose to this products to rain or moisture. The
product must not be exposed to dripping and splashing
and no object filled with liquids such as a vase of flowers
should be placed on the product.
DO NOT allow foreign objects to fall into the units.
NO naked flame sources, such as lighted candle must be
placed on the products.
NEVER remove any components and refer all servicing to
qualified personnel.
DO NOT change any connections before your system is
switched off.
DO NOT use your amplifier at its maximum volume setting.
The resulting high levels of distortion may damage your
loudspeakers.
DO turn down the volume control on your amplifier or
receiver before turning the equipment on or off.
The product should be mounted to a wall or ceiling only
as recommended by the manufacturer.
PREPARATION
MOUNTING
Connect the cable to the speaker. The speaker should
ideally be sited 0.6-1.5 metres above the listening position
and 2.5-3.5 metres apart, central to the listener and behind
the listening position, preferably on a rear wall. If the
listening position is some distance from a rear wall, the
loudspeakers may be mounted on opposite side walls but
always behind the listening position.
Ensure that the wall is sound and can support the product.
Drill two 5mm holes in the wall 200mm apart and
horizontally aligned. Fix a suitable No.8 round head screw
firmly into each hole using appropriate wall plugs. Leave a
stub of 5mm protruding from the wall.
Align the holes in the mounting brackets over the screw
heads and carefully lower the unit onto the screws. The
speaker should now be securely attached with the spacers
resting against the wall. Now connect the speakers to the
amplifier.
Note: As an alternative, the WH-DFS can be shelf or stand
mounted. The badge on the WH-DFS can rotate to match
the orientation of the loudspeaker.
LOUDSPEAKER SIZES
Many digital AV Processors require you to specify the size
of speakers in various channels. These are usually'Large'
or 'Small'. You must select 'Small' for the rear channels.
Selecting 'Large' may degrade the performance of the WH-
DFS. Set the subwoofer option on the processor to 'On' or
'Yes'. This will route all the deep bass to the subwoofer.
Each speaker is supplied with four self-adhesive spacers.
Apply on to each rear corner before mounting the unit.
CHOOSING AND PREPARING CABLES
Specialist audio cable offers better performance than
general purpose 'zip' or 'bell' wire. Choose a cable of
suitable diameter- cable that is too thin will limit the
dynamics of the sound and may impair the bass response.
Audio cable is polarised, with two cores of different
colours or often a raised rib or coloured tracer in the case
of twin cable. Split the cable at each end to a depth of
25mm. Strip about 7mm of insulation from each end and
lightly twist to gather the wire stands.
When connecting cables, ensure that there are no loose
stands which may touch adjacent terminals.
CONNECTING WIRES
When wall mounting a loudspeaker the connecting cables
may be unacceptably obvious. It may be less obstrusive to
route cables from the loudspeaker to the ceiling and then
within or underneath the ceiling or coving. The cable may
return to floor level at a convenient room corner.
CARE AND MAINTENANCE
NEVER touch the drive units which can be easily damaged.
The loudspeaker cabinet can be cleaned with a damp
cloth or with a spray furniture polish and a soft cloth.
Apply the spray sparingly to the cloth and then polish the
cabinet. NEVER apply spray directly to the cabinet.
Please refer to the relevant drawing on the facing page for
guidance and further information.
