Preparing the Diamond 100 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 beꢀer 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 oſten 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 leſt 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 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 100 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 leſt 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 155, 156, 157 and 159 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 121 and 122 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.
121 - 122
155 - 159
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 Leſt 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-WIRED CONNECTION
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.
RIGHT SPEAKER
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.

Connecting Centre Loudspeaker
The Centre channel speaker may be connected as shown, or bi-wired.
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
LFE
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
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.
If you are using a subwoofer: When set to ‘Small’ all the system bass will go into the subwoofer. If you choose ‘Large’ the Front channel bass will
be reproduced from the Front speakers. Follow the instructions on this page for suitable size and crossover seꢀings.
Once the loudspeaker seꢀings have been finalised, put the A/V amplifier into its ‘Test’ mode (see instructions supplied with your processor).
Adjust the level of each channel 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 seꢀing 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 A/V processor.
The subwoofer volume control should be between 12 o’clock and 3 o’clock.
Delay and LFE Settings
Many A/V processor feature delay seꢀings. 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 seꢀing
the distance from the listening position to each speaker, but other system allow only a time delay seꢀing.
Rear Delay: If the listening position is equidistant from the front and rear speakers, set a low delay seꢀing. The closer the listener is to the rear
speakers this higher the delay seꢀing 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. In domestic systems the LFE channel
typically feeds into the subwoofer. Where no subwoofer is used, the LFE signal is combined with the front channels and sent to the front
speakers. When you set the LFE level at your A/V processor, use care as powerful low frequencies can overload domestic loudspeakers. If you
hear popping or thumping noises coming from the front loudspeakers or subwoofer, immediately turn the A/V 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.
Phase: Please read the relevant sections of your A/V amplifier manual and familiarise yourself with the various issues. If you are unsure, consult
your dealer for help. A home theatre system should have a precise front stage, a diffuse rear stage and good localization of dialogue. If the
colours on the loudspeaker terminals do not correspond with those on the amplifier, the sound will appear poorly focused or ‘out of phase’. For
this reason it is essential that the speakers are connected according to the wiring diagrams in this manual.
Connecting loudspeakers correctly (in phase) is essential whether the system is stereo or multichannel. This is especially important if you are bi-
wiring – if only one element in a bi-wired system is incorrectly connected (out of phase), the effects can be very noticeable yet hard to pinpoint.
Troubleshooting
Before investigating a problem, always switch off the system at mains.
If your system is not working properly please work through this checklist before returning the unit to your dealer.

Looking After Your Loudspeaker
·
Your loudspeakers use special hardwearing 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 soſt 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 jardinières!
Avoid geꢀing any liquid behind the grille. If you spill liquid on your loudspeakers, take them to your dealer for aꢀention 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.
