Bowers & Wilkins 800 Diamond Serie Manual De Instrucciones página 6

The 803 Diamond and 804 Diamond can be fitted
with either rubber or spike feet – both are supplied in
the accessory pack. We would recommend that the
spike feet are used whenever possible. The spike feet
are designed to pierce carpet and rest on the floor
beneath, both to protect the carpet from indentation
and to provide the speaker with a solid foundation.
Note: Spike feet can be used on delicate non-
carpeted floors by standing the spikes on coins.
Fit either the spike or rubber feet by screwing them into
the four screw holes in the underside of the speakers.
In both cases, initially screw the lock nuts fully onto
the thread of the feet before screwing them into the
speaker. Hand tighten the feet. The diagram above
illustrates fitting spike or rubber feet.
Once the spike or rubber feet are fitted, the speakers
can be turned upright. Take care not to allow the entire
weight of a speaker to rest at an angle on one or two
spike feet as it is turned. Also take care that careless
handling with spikes fitted does not cause injury.
If the speaker rocks when placed on the floor in its
final position, or the thickness of carpet means that
the spike points do not reach the under-floor, adjust
the relevant feet until the speaker is supported firmly
without rocking. Using a 10mm spanner, re-tighten the
lock nuts against the underside of the speaker when
adjustment is complete.

4. Connecting
All connections should be made with the audio
equipment switched off.
The 803 Diamond and 804 Diamond speaker terminals
accept a variety of cable terminations: 4mm banana
plugs, 6mm and 8mm (1/4 in and 5/16 in) spades, or
bare wires up to 4mm (5/32 in) diameter.
Important Safety Notice
In certain countries, notably those in Europe,
the use of 4mm banana plugs is considered
a potential safety hazard, because they may be
inserted into the holes of unshuttered mains supply
sockets. In order to comply with European CENELEC
safety regulations, the 4mm holes in the ends of the
terminals are blocked by plastic pins. If you are using
the products in any country where these conditions
apply, you should ensure that any banana plugs cannot
be used in an unsafe manner by children or other
uninformed persons.
Ask your dealer for advice when selecting speaker
cable. Keep its total impedance below the maximum
recommended in the speaker specification and use
a low inductance cable to avoid attenuation of high
frequencies.
There are two pairs of terminals at the back of each
speaker that enable bi-wiring (top). For conventional,
single wire connection, fit the supplied link wires to join
the like polarity terminals together.
Ensure that the positive terminals on the speaker (with
red ring) are connected to the positive output terminal
on the amplifier and the negative terminals on the
speaker (with black ring) are always connected to the
negative output terminal on the amplifier. Incorrect
connection will not result in damage but will cause poor
stereo imaging and loss of bass. Always screw the
terminal caps down fully to prevent rattles.
N ote: Bi-wiring separates the signal paths to each
section of the speaker and can improve both stereo
imaging and detail resolution. It also enables the use
of different types of cable for each frequency band.
