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,
