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)
• Remove the staples from the top
carton flaps.
• Fold the carton flaps right back and
invert the carton and contents.
• Lift the carton clear of the contents.
• Remove the polystyrene packing from
the end and sides of the speaker.
• Open the polythene bag and pull it
clear of the base of the speaker.
• Turn the speaker right way up and
remove the final polystyrene tray and
polythene bag.
• Remove the transit clamp from the rear
of the speaker, following the
instructions on the label.
We suggest you retain the packing for
future use.
Check in the carton for:
• 4 spike feet with lock nuts.
• 2 terminal link cables
• Cleaning cloth
Wood is a natural material and veneers vary
between batches. Although supplied as
single units, systems with consecutive
serial numbers (odd number lower) have
veneer-matched cabinets. Please be aware
that if more than two speakers are
purchased for a single installation, B&W
cannot guarantee they will all be veneer
matched.
Positioning (figure 2)
Do not fit the spike feet until you have
found the best position for your speakers.
To find the optimum position in the room
may involve a certain amount of
experimentation, but as an initial guide:
• Position the speakers and the centre of
the listening area approximately at the
corners of an equilateral triangle.
• Keep the speakers at least 2m apart to
maintain left-right separation.
The proximity of the speakers to walls
affects the sound quality.See the
section“Fine Tuning” below.
Stray magnetic fields
The speaker drive units create stray
magnetic fields that extend beyond the
boundaries of the cabinet.
We recommend you keep magnetically
sensitive articles (television and computer
screens, computer discs, audio and video
tapes, swipe cards and the like) at least
0.5m 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. The lower
pair feed the bass and the upper pair feed
the midrange and 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
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,
