Wharfedale Pro DIAMOND 8 Series Instruction Manual

Congratulations on your purchase of loudspeakers from the Wharfedale
DIAMOND 8 range. These speakers have been designed to suit your lifestyle
so please spend a few minutes to look through this manual which has been
written to help you get the best from your new purchase.
UNPACKING
Unpack your loudspeakers with care. After taking out the top-most packing piece the
loudspeakers can be lifted from the carton and the polythene bags removed. Check
each loudspeaker after unpacking and in the event of any transit damage, immediately
contact your Wharfedale dealer. We suggest that you retain all the packaging, in case
you need to move the loudspeakers at some later date.
ANCILLARY EQUIPMENT
Your Wharfedale loudspeakers have been designed to be compatible with the great
majority of the hi-fi and audio visual equipment currently available and so we would not
anticipate any significant problems in matching up your system. However, if you have
any doubts your dealer will be happy to advise you.
Remember that a loudspeaker can only reproduce the signal with which it is fed. If the
recording is bad; the reception of a radio is poor or if the amplifier is distorting, then
this will be faithfully reproduced as an unpleasant sound. For this reason you should
install the best equipment you can afford and in particular, you should select an
amplifier which has good reserves of output power. A high output amplifier will usually
sound better than a low powered one and will enhance the reliability of your
loudspeakers. This is because a small amplifier will 'clip' the music signal when it is
asked to deliver a higher output level, beyond that which it is capable of. The resulting
clipped signal generates unusually high levels of high frequency distortion which can
stress or even damage the tweeter units. For this reason you should always turn down
the volume if the music starts to sound distorted.
CONNECTING THE LOUDSPEAKERS TO YOUR SYSTEM
Always ensure that the amplifier and all associated components are switched OFF
before connection commences.
NEVER CONNECT THE MAINS ELECTRICITY SUPPLY TO YOUR LOUDSPEAKERS
Connect the left hand speaker to your amplifier's left hand channel, taking care to
connect red to red and black to black. Repeat this for the right hand speaker.
BINDING POST TERMINALS - EUROPEAN SAFETY REGULATIONS
This loudspeaker has been fitted with plastic blocking plugs on the terminals in order to
conform with European safety regulations. Customers outside of the European Union
who wish to remove these plugs can do so by carefully inserting the tip of a penknife or
other pointed tool under the plug and gently prising it out.
Separate terminals are provided for feeding the low and high-frequency drive units. You
will see that the red terminals are connected together, as are the black; by two metal
links. If you wish to use the system conventionally leave the links in place and connect
to the amplifier as shown in the diagram. However improved performance can be
obtained by either bi-wiring or bi- amping the speakers.
To do this, first remove the metal links connecting the pairs of terminals. In the case of
2 NORMAL WIRING
4 BI-AMPING
bi-wiring connect each of the red terminals on the speaker via separate cables to the
red output terminal on the amplifier. Repeat the process for the black terminals. Take
care that the left channel outputs are fed to the left hand speakers and similarly for the
right hand side. Bi-amping is similar to the above but requires the use of two stereo
amplifiers as shown in the diagram.
ROOM POSITIONING
Your DIAMOND 8 loudspeakers offer great flexibility of positioning within your home.
Depending upon the model they can be positioned upon shelves, on stands or directly
on the floor.
All the models can be positioned as close as 0.5m - 1m from a side facing wall. There
must be a distance of at least 0.7m - 1m between the backs of the cabinets and the
walls. If the loudspeakers are positioned close to the wall they should ideally be angled
inwards slightly and be separated by a distance of 3 metres.
The performance of the DIAMOND 8 loudspeakers may be improved by positioning
them further away from the back wall, if you have enough room. In that case you can
angle them inwards by 40 degrees, as shown in the diagram.
The DIAMOND 8.1, 8.2 should ideally be placed on loudspeaker stands or wall brackets
well away the floor, with the top of the cabinet at approximately eye level when seated in
your normal listening position. As an alternative, use bookshelf mounting.
The DIAMOND 8.1, 8.2 loudspeakers are designed for shelf mounting; wall mounting or
stand mounting. A number of suitable floor stands and wall brackets are available and
your dealer will be pleased to recommend suitable designs.
As a general rule the level of the bass output will be higher when the loudspeaker is
positioned close to a wall and lower when the loudspeaker is positioned away from a
wall or walls. If you have the space and flexibility in positioning you can use this
characteristic to adjust the tonal balance to your own taste.
CARE AND MAINTENANCE
Very little maintenance is required. The cabinets can be occasionally wiped with a damp
(not wet) cloth. Spray polishes can be used but they must not be sprayed onto the
grilles or drive units. Indeed it is best to spray the polish onto a cleaning cloth not the
loudspeaker.
You may listen to the loudspeakers with the grilles removed and some listeners may
well prefer the resulting sound but remember that the grilles perform the function of
protecting the drive units.
If you wish to clean the grilles this may be done by removing them and gently
vacuuming their surface. Solvent based cleaners must be avoided; minor stains are
best removed with soap and lukewarm water.
