Wharfedale Atlantic AT-100 - Manual (Page 2)

Congratulations on your purchase of loudspeakers from the Wharfedale
ATLANTIC 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 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 ATLANTIC 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
meters.
The performance of the ATLANTIC 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 ATLANTIC AT-100,200,300 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 ATLANTIC AT-100,200,300 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.
CARE MUST BE TAKEN TO AVOID CONTACT WITH
THE DRIVE UNITS AS THEY ARE EASILY DAMAGED.
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.
