loudspeakers should ideally be stand mounted though they may be
placed on a rigid shelf. The loudspeakers also feature a threaded
mount which accepts our specially designed wall bracket. Several
floor stands and alternative wall brackets are available and your
dealer will be pleased to recommend suitable designs.
The loudspeaker drive units are screened so they may safely be
placed close to a TV screen without degrading the colour balance.
Your speakers can be positioned as close as 0.5m - 1m from a side
wall. Ideally there should be at least 200mm between the backs of
the cabinets and the walls. If the loudspeakers are positioned close
to the wall they should be angled inwards slightly and be separated
by a distance of 3 metres. If the loudspeakers are placed further
away from the walls, the inward angle may be increased by up to
40%, although this may restrict the width of the listening position.

Diamond 75th Anniversary Special D9.1 Installation and User Guide
Connecting and Using Your Loudspeakers
Crossover Networks
Your loudspeakers use a specially
designed bi-wireable crossover
panel with four terminal binding
posts. Please follow the drawing
carefully to see the correct
orientation of the loudspeaker
terminals. The upper terminals
connect to the treble unit, the
lower pair to the bass unit. As
supplied, the treble terminal pair
is connected to the bass terminal
pair via removable metal straps.
These should beleft in place for
standard installations.
Unscrew each terminal a few turns and remove the metal straps.
Connect the cables between the amplifier and the loudspeakers as
indicated below and re-tighten all the terminals securely.
Home Theatre
The 70th Anniversary loudspeakers are ideal for Home Theatre.
To complete the system you should choose the Centre and Effects
speakers with a pertnering subwoofer from our award-winning
Wharfedale Diamond 9 range
Standard Connections
Choose a suitable length of twin
core speaker cable for each channel, and prepare the ends as
described above.
Connect the Red, positive (+) terminal of the Left loudspeaker to
the corresponding Red, positive (+) amplifier terminal; connect the
Black, negative (-) terminals similarly. Repeat for the Right Channel.

of twin core cable between the amplifier and each loudspeaker.
Ancillary Equipment
A loudspeaker is only as good as the signal it gets. Your amplifier
should have ample power - a low powered amplifier could run out
of steam and the distortion is unpleasant to listen to and could
damage your speakers. A large amplifier will sound better and
enhance the reliability and performance of your loudspeakers.
Running In
Loudspeakers need a 'running in' period. For the first 50 hours or
so exercise care and play your system at reasonable volume levels.
After running in, you will notice a significant sonic improvement.
Care and Maintenance
The cabinets can be occasionally wiped with a damp (not wet)
cloth and buffed with a soft cloth.To clean the grilles, remove them
and brush gently with a soft brush. Never use solvent cleaners,
minor stains are best removed with soap and lukewarm water. Do
not touch the drive units as they can easily be damaged.
A typical Home Theatre system is illustrated. The Front
loudspeakers should be placed on either side of the television
screen, 2 to 4 metres apart. For fuller operating details, consult
your AV processor, subwoofer and effects loudspeaker manuals.
Many digital AV Processors require you to specify the size of
speakers in the various channels. These are usually ‘Large’ or
‘Small'. The Rear and Centre channels should be set to 'Small'.
If a sub bass unit is in use set the Front channels to 'Small'. All the
bass will now be routed through the sub bass unit. If no sub bass
unit is in use, set the Front Channel to 'Large'. All the system bass is
now routed through the Front speakers. Set the subwoofer channel
on the processor to ' No' or 'Off'.
If your AV processor has an LFE control, use care as the LFE
channel may contain heavy low frequencies which can overload a
domestic unit. If you hear popping or thumping noises coming
from the Front speakers or the sub bass unit, turn the AV
Processor's volume level down and back off the LFE level.
