Preparing
the
DIAMOND
12
Loudspeakers
Stands
and
Brackets
The bookshelf loudspeakers are intended primarily for stand mounting, though they can be
mounted
on
wall
brackets
or
even on sturdy
shelves. The quality
of
loudspeaker stands greatly influences the performance
of
your loudspeakers, please
do
not
use flimsy products.
Centre
Channel
Loudspeakers
Each centre channel loudspeaker
is
supplied with
one
set
of
mounting feet. By using combination
of
large and small
feet
the loudspeaker may
be
angled to point directly
at
the listening position. This
will
be found useful when the centre speaker
is
positioned under the TV screen.
Cables
and
Connectors
Choosing
Loudspeaker
Cable
Specialist audio cable usually offers
better
performance than general purpose '
bell
'
or
'zip' wire.
Choose a cable
of
suitable diameter - cable that
is
too
thin
will
limit the dynamics
of
the
sound and
may
impair the bass response. Audio cable
is
polarised, with
two
cores
of
different colours,
or
often a raised rib
or
coloured tracer
in
the case
of
twin cable. Before you purchase your cable,
give careful
thought
to
the positioning
of
your loudspeakers.
This
is
especially the case
if
you are bi-wiring your loudspeakers. ' I
~Im
Cable lengths
to
loudspeaker pairs should be the same for
left
and right channels
in
order to equalise the signal
transmission.
Allow
some slack in your speaker cables so you can alter their position
to
best advantage.
40mm
Preparing
Loudspeaker
Cable
' a
Split
the
twin cores
to
a depth
of
about 40mm. Carefully strip the insulation from each end, leaving about 10mm
of
bare wire. If
the
cable
is
stranded, lightly twist
to
gather any loose strands.
Connecting
Screw
Terminals
All
loudspeakers use screw terminals.
Unscrew the terminal. Insert the bare end
of
the cable into the hole
in
the base
of
the terminal. Tighten securely.
When connecting terminals make sure you leave no strands
of
bare wire that can short across
to
adjacent terminals.
As an alternative to bare wire you can use specialist spade connectors. Your Wharfedale dealer
will
be
pleased
to
advise you on this issue.
Crossover
Networks
Bi-Wireable
Networks
Most speakers
in
the DIAMOND
12
floorspeaker eaker use a special bi-wireable crossover panel with four
terminal binding posts. Please follow the drawing carefully
to
see the correct orientation
of
the
loudspeaker terminals.The upper terminals connect to the treble unit. the lower pair
to
the bass unit.
As
supplied. the treble terminal pairis connected
to
the bass terminal pair via removable metal straps.These
should
be
left
in
place for standard installations.
Why
Bi-Wire?
Using separate cables for treble and bass units
in
a bi-wiring configuration reduces intermodulation effects
and improves headroom and clarity. To bi-wire, you
will
need to install
two
lengths
of
twin core cable
between the amplifier and each loudspeaker.
