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.

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.

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

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.

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

>0.7metre

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.

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

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 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 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.
