Wharfedale Diamond 12 Series Loudspeakers User Manual (+ PDF)

The DIAMOND 12 Series is a range of loudspeakers, including the
DIAMOND 12.0, DIAMOND 12.1, DIAMOND 12.2, DIAMOND 12.3, DIAMOND
12.4, DIAMOND 12.C, and DIAMOND 12 3D SURROUND models. These
loudspeakers are known as Britain’s most famous loudspeakers.

Important Safety Information

Before installing this product, it is important to read all the
instructions provided. The symbol in the manual indicates that
there are important operating and maintenance instructions
included.

Unpacking Your Loudspeaker

When unpacking your loudspeaker, ensure that you handle it with
care and follow the instructions provided in the manual.

Levelling the Loudspeakers

To ensure optimal performance, it is recommended to level the
loudspeakers properly. Follow the instructions in the manual for
leveling guidance.

Preparing the DIAMOND 12 Loudspeakers

The bookshelf loudspeakers in the DIAMOND 12 series are
primarily intended for stand mounting. However, they can also be
mounted on wall brackets or sturdy shelves. It is important to note
that the quality of loudspeaker stands greatly influences the
performance of your loudspeakers, so avoid using flimsy
products.

Centre Channel Loudspeakers

Each centre channel loudspeaker comes with a set of mounting
feet. By using a combination of large and small feet, you can angle
the loudspeaker to point directly at the listening position. This
is particularly useful when positioning the centre speaker under a
TV screen.

Cables and Connectors

Choosing the right loudspeaker cable is important, especially if
you are bi-wiring your loudspeakers. Ensure that the cable lengths
to loudspeaker pairs are the same for left and right channels to
equalize signal transmission. Leave some slack in your speaker
cables to allow for positioning adjustments.

Preparing Loudspeaker Cable

To prepare the 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 in the DIAMOND 12 series use screw terminals.
Unscrew the terminal, insert the bare end of the cable into the
hole in the base of the terminal, and tighten it securely. Ensure
that no strands of bare wire are left that can short across
adjacent terminals. Alternatively, you can use specialist spade
connectors.

Crossover Networks

Most speakers in the DIAMOND 12 series use a special bi-wireable
crossover panel with four terminal binding posts. Follow the
instructions carefully to see the correct orientation of the
loudspeaker terminals. The upper terminals connect to the treble
unit, while the lower pair connects to the bass unit. Metal straps
are provided to connect the treble and bass terminal pairs, which
should be left in place for standard installations.

Why Bi-Wire?

Bi-wiring 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 D12.3 and D12.4 models are designed to be floorstanding and
should be positioned at least 200mm from the rear walls and 700mm
from the side walls, facing slightly inwards. The D12.0, D12.1, and
D12.2 models can be stand or wall-mounted, but they may also be
placed on a rigid shelf. The bass extension will improve if the
small speakers are operated closer to the rear wall.

User Manual

Important Safety Information
Before installing this product read all these instructions! This symbol indicates that there are important operating and maintenance instructions in the literature accompanying this unit.
Read these instructions. Keep these instructions. Heed all warnings. Follow all instructions. Before making any connections, switch all the units in your system off at the mains. Set the volume control at minimum when you switch on your system or change sources, and turn the level up gradually. DO NOT use your amplifier at full volume. Ensure that all loudspeakers in the system are correctly wired. DO NOT subject your loudspeakers to excessive cold, heat, humidity or sunlight. Loudspeakers should not be placed directly facing other hi-fi units, or share the same shelf or cabinet. DO NOT place heavy objects on top of loudspeakers. Some manufacturers forbid the placing of objects on top of their TV sets. Check your TV handbook before installing the speaker directly on your TV set. Consult your TV dealer if you are in any doubt. DO NOT connect speaker terminals to the mains supply. DO NOT dismantle the loudspeaker. There are no user serviceable parts inside it and you will void the warranty by doing so. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. Caution: Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate this device.
Unpacking Your Loudspeaker
DIAMOND 12 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 D12.3, D12.4
· 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. · Thread a locknut onto each spike and loosely rub it up the thread. · Thread the spikes into the spike inserts. Tighten them with 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 with 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 squarely on all four spikes without rocking. Now tighten each locknut 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 the same manner as the spikes.

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.
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 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

H F

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?

–

B A S S –

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 D12.3 and D12.4 models are designed to be floorstanding. We suggest that they are positioned at least 200mm from the rear walls and 700mm from the side walls, facing slightly inwards. The D12.0, D12.1 and D12.2 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.

2 – 4 metres

D12.0, D12.1, D12.2 >50 mm
D12.3, D12.4 >200mm

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.

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.

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 settings.
Once the loudspeaker settings 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 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 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 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, but other system allow only a time delay setting.
Rear Delay: If the listening position is equidistant from the front and rear speakers, set a low delay setting. The closer the listener is to the rear speakers this 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. 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 biwiring 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 soft brush before replacing them carefully.
· We advise that you do not use a vacuum cleaner to clean loudspeaker grilles.
· We advise that you do not place anything on your loudspeakers to prevent damage to the cabinet surface.
· 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. 8
