If there is no carpet and you wish to avoid scratching
the floor surface, use either a protective metal disc, a
spike cup or a coin between the spike and the floor,
or use the supplied rubber feet. Fit the rubber feet and
level the cabinet or stand in the same manner as with
the spike feet.
Speaker Positioning
In either stereo or home theatre installations, try to
ensure that the immediate surroundings of each
speaker are similar in acoustic character. For example,
if one speaker is adjacent to bare walls while the other
is adjacent to soft furnishings and curtains, both
the overall sound quality and the stereo image are likely
to be compromised.
Conventional Stereo Systems
To begin with, the speakers should be positioned
between 1.5m and 3m apart at two corners of an
equilateral triangle completed by the listening area at
the third corner. The speakers should be approximately
0.5m away from the back wall, and at least 0.5m
away from any side walls (above).

Home Theatre Systems
If the speakers are to be used for the front channels
in a home theatre system, they should be placed
closer together than for 2-channel audio, because the
surround channels tend to widen the image. Positioning
the speakers within approximately 0.5m
of the sides of the screen will also help keep the
sound image in scale with the visual image. As with
conventional stereo positioning, the speakers should
ideally be at least 0.5m away from any side walls. If you
would prefer to place your speaker against the back
wall and this location results in over emphasised
bass, see the Fine Tuning section of this manual for
information on using the foam plugs.

All connections should be made with the audio

The 805 D3 and 804 D3 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.
