Owner’s manual
Introduction
Thank you for choosing B&W.
Your Nautilus™800 Series speakers are
precision transducers incorporating many
innovative techniques unique to B&W and
capable of reproducing recorded sound to
the highest standards. So that they may
perform at their best, it is essential to take
time and care with the installation process.
In particular, you must regard the listening
room as an extension of the speaker. The
acoustic character of the room can have a
profound effect on the final sound quality.
Please read this manual fully before
unpacking and installing the product. It will
help you to optimise its performance.
B&W maintains a network of dedicated
distributors in over 60 countries who will be
able to help you should you have any
problems your dealer cannot resolve.
Unpacking (figure 1)
• Fold the carton flaps right back and
invert the carton and contents.
• Lift the carton clear of the contents.
• Remove the polystyrene tray from the
top of the speaker.
• Lift the speaker out of the lower tray
and, resting one end side back on the
tray for protection, open and remove
the polythene bag.
We suggest you retain the packing for
future use.
Check in the carton for:
• 4 self-adhesive rubber pads.
• 2 terminal link cables.
• Cleaning cloth.
Wood is a natural material and veneers vary
between batches. Expect some variation in
the finish between all the speakers in a
home theatre installation.
Positioning (figure 2)
If using a projection television with an
acoustically transparent screen, place the
speaker behind the centre of the screen.
Otherwise position it directly above or
below the screen, whichever is closest to
ear level. Align the front of the speaker
approximately level with the screen.
Fix the 4 self-adhesive pads to the base of
the speaker. They give a degree of vibration
isolation, especially useful if placing the
speaker directly on top of a fairly flimsy
television. The flat area on top of the
television may be smaller than the base of
the speaker, so position the feet
accordingly.
Alternatively, if you require more isolation or
the support surface is not quite flat, you
may use 4 pieces of malleable re-usable
adhesive (for example Bostik® Blu-Tack®).
Stray magnetic fields
The speaker drive units are magnetically
shielded such that the stray magnetic field
outside the boundaries of the cabinet,
except the front, is too low to cause
distortion of the television picture in the
vast majority of cases.
There are, however, some extremely
sensitive televisions - some that even have
to be adjusted according to their alignment
with the earth’s magnetic field. If you have
a problem, first de-gauss the television set
with the speaker in place. Some have a
button specially for this purpose. If not,
switch off the set at the mains for 15
minutes and switch on again. Merely
putting the set into standby mode is not
sufficient.
If you still have a problem, try moving the
speaker either forwards or backwards a
little to get a more favourable juxtaposition,
or space the speaker further from the
television until the distortion disappears.
Because of the higher stray magnetic field
in front of the speaker, we recommend you
keep magnetically sensitive articles
(computer discs, audio and video tapes,
swipe cards and the like) at least 0.2m from
the speaker.
Connections (figure 3)
All connections should be made with the
equipment switched off.
There are 2 pairs of terminals at the back of
the speaker to permit bi-wiring. In the
Nautilus™HTM1, the lower pair feed the
bass units and the upper pair feed the
midrange and tweeter. In the
Nautilus™HTM2, the lower pair feed the
bass/midrange drive unit and the upper pair
feed the tweeter.
The terminals are insulated to prevent any
likelihood of electrical shock, even when
the speakers are used with the highest
powered amplifiers, and accept a variety of
cable termination to suit most applications.
Bi-wiring is the preferred method of
connection and involves the use of
separate cables from the amplifier to each
pair of terminals. The separation of the
signal paths improves the resolution of low-
level detail and allows the user to optimise
the type of cable to the frequency range of
use.
Should you not want to bi-wire, perhaps
during the initial set-up procedure or
because you do not want to see a
multitude of cables in the room, short
cables are provided to link both positive
and both negative speaker terminals
together.
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
