Unpacking Your Loudspeaker
Diamond 200 loudspeakers come in different shapes and sizes. If you are unpacking a floor stander, please remember that these units are heavy .
We suggest that you have someone to assist you.
Lift the
loudspeaker carefully out of the packing. DO NOT try and lift the loudspeaker using the protective bag.
Unpack the accessories carefully.
If there is any sign of damage or if the contents are incomplete, report this to your dealer as soon as possible.
Retain the packing for future safe transport of the product.
If you dispose of the packing, do so with respect to any recycling provisions in your area.
Attaching the Spikes to Floorstanding Models- REVA-3/REVA-4
Make sure you have plenty of unobstructed working space.
Place a soft cloth
on the floor to protect the loudspeaker.
Invert the
loudspeaker onto the cloth.
T
hr ead a locknut onto each spike and loosely rub it up the thread.
Thread the spikes into the spike inserts. Tighten
them finger tight.
Invert the loudspeaker.
Be careful not to damage the floor with the spikes.
Levelling the Loudspeakers
When the speaker is upright: You will probably find that the speaker will wobble wit h one spike not contacting the floor. Adjust this spike until
all four spikes are in contact to the floor.
With the aid of a
spirit level move each spike in and out until the loudspeaker is level and sitting spuarely on a ll fore spikes wit hout rocking.
Now tighten each l ocknut securely against the collar in the plinth to secure the spike.
Screw in
rubber feet are provided for use on wood or stone floors etc. and should be attached in th e same manner as the spikes.
Spike Seats
A set of spike seats is provide to provided to protect sensitive floors from possible damage.The loudspeaker should
be mounted on the wide spikes and the spike seats should be placed under each spike as sh own .Level the loudspeakers
with the spiker seats in place.
Using the Spike Seat

Preparing the REVA 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
two sets 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.
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.
Preparing Loudspeaker Cable
Split the
twin
cores to a
depth
of
about
40mm. Carefully strip the
insulation
from each
end,
leaving
about
lOmm 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
REVA series
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
pair
is 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.

Positioning the Front Loudspeakers
The
REV
A-3,REVA-4
models
are
designed
to be floor standing.
We
suggest
that
they are positioned
at
least 200mm from the rear walls
and
700mm from the side walls, facing slightly inwards. The
REV
A-1
and
REV
A-2 models
should
be
stand
or
wall
mounted
though
they
may
be placed
on
a rigid shelf. The bass extension will
improve
if the small speakers are
operated
closer to the rear wall.
If
the loudspeakers are placed too close to the walls the bass will increase
but
may
be
boomy
and
indistinct.
If
the
loudspeakers
are placed
away
from the walls, the
inward
angle
may
be increased
by
up
to
40%,
although
this
may
restrict the
width
of the
optimum
listening position.
A useful rule of
thumb
is that the listener should be as for from the
loudspeakers
as they are from each other. The speakers
should
ideally be
positioned so that the treble
units
are roughly at
ear
level to s seated listener. As personal taste plays a large role,
experiment
with different
configurations
and
play a
wide
range
of
programmes
before finalising the position of
your
speakers.
Positioning the
Centre
Loudspeaker
The centre channel
loudspeaker
should
be positioned centrally
between
the loudspeakers, close to the television
and
mounted
above
or
below
the screen.
The
loudspeaker
should
be located
on
a stable flat surface to avoid
any
cabinet
movement
at
high
sound
levels.
If
you
mount
the
unit
above the television,
move
it
forward
so
that
the front grille sits
slightly
in
front of the screen
and
the top of the cabinet.
A
custom
stand
is available for the
model
which
allows the
loudspeaker
to be
positioned
under
a
wall
mounted
monitor
and
has
an
adjustable vertical tilt for optimal dispersion.

Connecting the Front Loudspeakers
Standard Connection
Choose a suitable length of twin core speaker cable for each
channel, and prepare the ends. Unscrew each terminal a few
turns.
Connect the red, positive(+) terminal of the Left loudspeaker
to the corresponding red, positive (+) amplifier terminal.
Connect the black, negative (-) terminals similarly. Tighten
the terminals securely. Repeat this procedure for the Right
channel.
Bi-Wiring
Unscrew each terminal a few turns and remove the metal
straps. Connect the cables between the amplifier and the
loudspeakers as indicated above and re-tighten all the
terminals securely.
Bi-Amping
By connecting each loudspeaker drive unit to its own
dedicated amplifier the advantages of bi-wiring can be
extended.
IF you own two indentical stereo power amplifiers, your
speakers may be bi-amped. For further details please consult
your dealer.

Setting Up a Home Theatre System
Placement
Front
and
Effects
Channels:
The
front
loudspeakers
are
placed
on
either
side
of
the
television screen, 2 to 3
metres
apart.
The
speakers
should
be
angled
slightly
so
they
car
aimed
towards
the listeners.
We
recommend
placing
the
rear
effects
speakers
in a
high
position,
behind
the
listener's head.
If
the
rear
or
side
walls
are
a
long
way
from
the
listening seat,
consider
stand
mounting
the
loudspeakers.
If
the
centre
loudspeaker
is
very
high
or
low,
angle
it
towards
the
listener's
ear
level.
The
front faces of
the
centre
and
surround
loudspeakers
should
also
be in line as far as possible.
Subwoofer:
As
the
ear
is
unable
to
detect
the
direction from
which
deep
bass originates, you
have
freedom
to
position
the
unit. Varying
the
distance
from
the
wall alters
the
bass.
Placing
the
subwoofer
across a
corner
boosts
the
bass
but
may
impair
clarity.
The
performance
of a
home
theatre
system
can
be
enhanced
by
using
two
subwoofers.
6.1
and
7.1
System Placement
Dolby
Labs,
DTS
and
THX
offer
6.1
and
7.1
format.
Although
the
precise
configuration
of
these
systems
will
depend
on
the
capabilities of
your
processor
and
you
should
be
guided
by
those
instructions,
we
would
make
some
observation.
For
6.1
and
7.1
formats
the
listening
seat
should
not
be
too
close
to
the
rear
wall.
Optimising
the
time
delay
so
that
information
from
all
speakers
arrives
the
listening
seat
coherently
is
critical of
the
benefits of
these
systems
are
to
be
fully realised.

Setting
Loudspeaker
Sizes
and
Levels
Most digital A/V Processors require
you
to specify the size of
speakers
in all channels.
There
are
usually
'large'
or
'small'.
Always
set the
REVA-1 to
'small'.
Depending
on
the size
and
capacity of
your
subwoofer
you
may
set
the REVA-2 to
'small'
or
'large'
.As the
Surround
channels will
most
likely be
REVA-lloudspeakers,
set
these to
'small'
as well.
IF
YOU ARE USING A SUBWOOFER
For the REVA-1
and
REVA-2
when
used as Front Speakers: Set these to 'small'. The
subwoofer
will
now
receive all the system bass signals.
For the REVA-3,
and
REVA-4: Set these to 'large'. The subwoofer
then
will
reproduce
only the
LFE
and
bass signals from the effects channels.
The REVA-2
may
be
set to either 'large' or small
depending
on
personel preference
and
the
capacity of the subwoofer.
If
you
are
not
using
a
subwoofer
: Set the front
speakers
to 'large'. Set the subwoofer option
on
the processor to 'Off' or
'No'.
The front
channels will
now
receive all the system bass.
Setting
Loudspeaker
Levels
Once the
loudspeaker
settings have
been
finalised,
put
the
AV
amplifier into its "test"
mode
(see instructions
supplied
with
your
processor).
Adjust the level of each channel
in
turn
until all channels are
reproduced
at equal loudness.
On
some
programme
material the
surround
channel
may
seem lower
than
the front. Do
not
readjust this level. You may, however,
need
to
adjust the subwoofer
output
level.
Avoid setting too
high
a level
or
you will
swamp
the
sound
with
bass. This can be tiring to listen to,
and
may
limit the subwoofer's ability to
!respond
to large bass transients.You
should
also set a sensible level going into the
subwoofer
from the
AV
processor.
Delay
Settings
Many
AV
processors feature delay settings. The
purpose
of delay is to enable
surround
and
dialogue information to arrive at the listener's ears
at
the
same
time as the front channels, even
when
the listening seat is in a non-ideal position.
On
some processors,this can
be
achieved
by
setting
the distance from the listening position to each
speaker
in turn,
but
other
systems allow only a time delay setting.
Rear Delay:
If
the listening position is equidistant from the front
and
rear speakers, a low delay setting
should
be set. The closer the listener is
to the rear
speakers
the
higher
the delay setting
used
should
be.
Centre Delay:
If
the centre
speaker
is level
with
(or slightly behind) the front speakers, set the delay to zero.
If
the centre speaker is forward of
the front speakers, increase the delay.
LFE
In the cinema the low frequency effects channel is
an
extra bass channel
with
its
own
subwoofer
and
not
a regular subwoofer channel.
In domestic systems the
LFE
channel typically feeds
into
the subwoofer.
Where
no
subwoofer is used, the
LFE
signal is combined
with
front
channel information
and
sent
to the front speakers.
When
you set the
LFE
level
at
your
AV processor,
use
care as the powerful low frequencies
can overload domestic loudspeakers.
If
you
hear
popping
or
thumping
noises coming from the front
loudspeakers
or subwoofer, immediately
turn
the AV Processor's
volume
level
down
and
then
lower
the
LFE
level. This
should
cure the problem.
If
it does not, lower the
volume
level at the subwoofer (if you are
using
one)
until the
problem
disappears.Please read the relevant sections of
your
A
V
ampl
ifi
er
manual
and
familiarise yourself with the various issues.
If
you are unsure, consult
your
dealer for help.
Phase
A
home
theatre system
should
have a precise front stage, a diffuse rear stage
and
good localisation of dialogue.
If
the colours
on
the
loudspeaker
terminals
do
not
correspond
with those on the amplifier, the
sound
will
appear
poorly focussed
or
'Out
of phase'. For this reason it is essential
that the speakers are connected accordingly to the
wiring
diagrams
in this manual.

Looking
After
Your Loudspeaker
Your loudspeakers use special
hard
wearing sealed finish. They
should
not
be
waxed or treated
with
spray polishes which will smear
and
dim the finish. Occasionally polish
them
with a
dry
or barely moist cloth to remove
dust
and
finger marks, etc.
If
you play the speakers
with
the grilles off exercise great care. NEVER operate speakers with the grilles off
if
there are children or pets in
the house.
Occasionally, remove the
loudspeaker
grilles
and
brush
them gently
with
a soft
brush
before replacing
them
carefully.
NEVER
use
a
vacuum
cleaner to clean loudspeaker grilles.
NEVER stand objects on
your
loudspeakers. In particular
do
not
stand
flowers etc. on
them-
they are
not
jardinieres!
Avoid getting any liquid
behind
the grille.
If
you spill liquid
on
your
loudspeakers, take them to
your
dealer for attention before using them
again.
DO
NOT
open
the speakers, there are no
user
serviceable
parts
inside.
NEVER touch the drive units either with
an
object or your
hands.
Quality Assurance
Your loudspeakers have been constructed to the highest standards. From top
grade
furniture construction
and
finish to carefully designed
and
selected acoustic components, Wharfedale speakers are built to
provide
a lifetime of sonic pleasure. We
