Français Garantie Limitée - Bowers & Wilkins Signature HTM Manual Del Propietario Y Garantía

When using the links, insert the spade into
the slot in the side of one terminal and the
crimped pin into the round side hole in the
other. There is enough clearance to insert a
spade connector from the amplifier into the
same terminal as the crimped pin.
Ensure each positive terminal on the
speaker (coloured red) is connected to the
positive output terminal of the amplifier and
negative (coloured black) to negative.
Incorrect connection can result in poor
imaging and loss of bass.
When bi-wiring, do not use the linking
cables. Take extra care with the polarity of
the connections as incorrect connection
can also impair the frequency response
through the bass-midrange crossover and,
if the links are left in place, may cause
damage to the amplifier by shorting its
output terminals.
Fine tuning
Before fine tuning, double check that all the
connections in the installation are correct
and secure.
For greatest realism in home theatre
installations it is important to balance the
speakers and adjust the acoustic image to
match the size of the screen. With smaller
screens it may be more realistic to have the
left and right speakers closer together than
you might for audio alone.
Adjust the levels of the three front speakers
to get a smooth transition of sounds as
they pan across the screen. Adjust the level
of the surround speakers so that, except
for special effects, your attention is not
unduly attracted to them.
Sit in all likely listening positions when
deciding on the optimum levels.
Consult your decoder manual for further
information on how to set the levels.
For the most discerning listening, remove
the cloth covered grille as described below
in the section "Aftercare". The tweeter is
very delicate and its grille should be left in
position for protection. For this reason the
grille retaining ring is designed to provide
the optimum acoustic environment for the
unit and the response is less smooth with
the grille removed.
Running-in period
The performance of the speaker will change
subtly during the initial listening period. If
the speaker has been stored in a cold
environment, the damping compounds and
suspension materials of the drive units will
take some time to recover their correct
mechanical properties. The drive unit
suspensions will also loosen up during the
first hours of use. The time taken for the
speaker to achieve its intended
performance will vary depending on
previous storage conditions and how it is
used. As a guide, allow up to a week for
the temperature effects to stabilise and 60
hours of average use for the mechanical
parts to attain their intended design
characteristics.

Ancillary equipment
Speakers of this ability deserve signals of
the highest quality. Choose your electronic
equipment and interconnecting cables with
care. We can give guidance on what to
look for when choosing ancillary
equipment, but cannot recommend specific
items. The standards of such products are
improving all the time and your dealer will
be able to demonstrate a variety of suitable
up-to-date products.
In the specification we recommend a range
of amplifier powers. The higher figure is
defined by the power handling capability of
the speaker. When calculating the power
handling, it is assumed that the amplifier is
not run into clipping, which distorts the
frequency power spectrum of the signal,
and that the signal is normal programme
material. Test tones from oscillators and the
like are not applicable. The lower figure is
the minimum we consider necessary to
achieve reasonable listening levels without
audible distortion in the smaller room (less
than 60 m 3 or 2000 cu ft). The higher the
power you use, the less likely you are to
experience amplifier clipping. You can often
tell how good an amplifier is at driving
complex speaker loads by looking at its
power rating into both 4Ω and 8Ω loads.
The nearer the ratio is to 2:1 the better, as
it indicates a good current capability.
In order to reduce the effect the cable has
on the frequency response of the speaker
to inaudible levels, the impedance of the
cable at all frequencies (measuring both
positive and negative conductors in series)
should be kept as low as possible and
certainly below 0.1Ω. At low frequencies,
the DC resistance of the cable is the
dominant factor and you should choose a
gauge of wire sufficient to achieve the
impedance requirements over the length of
cable you need to use. At mid and high
frequencies the inductive component of the
impedance can dominate the DC
resistance. This and other properties
influenced by the detailed construction of
the cable become important. Ask your
dealer for advice on the best cable for your
needs.
Aftercare
The cabinet surface usually only requires
dusting. If you wish to use an aerosol
cleaner, remove the grille first by gently
pulling it away from the cabinet. Spray onto
the cleaning cloth, not directly onto the
cabinet. The grille fabric may be cleaned
with a normal clothes brush whilst the grille
is detached from the cabinet.
The surface of the tweeter housing will
benefit from the use of an anti-static
cleaner. Do not attempt to remove the
tweeter grille.
Avoid touching the drive unit diaphragms,
especially the tweeter, as damage may
result.
