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 o 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 amplier 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- 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 qualied 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 modications not expressly approved by the manufacturer could void the user's authority to operate this device.

Unpacking Your Loudspeaker

Diamond 100 loudspeakers come in dierent shapes and sizes. If you are unpacking a oor stander, please remember that these units are heavy.

We suggest that you have someone to assist you.

Li the loudspeaker carefully out of the packing. DO NOT try and li 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 – 155, 156, 157, 159

· Make sure you have plenty of unobstructed working space.

· Place a so cloth on the oor 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 nger tight.

· Invert the loudspeaker. Be careful not to damage the oor with the spikes.

Levelling the Loudspeakers

When the speaker is upright: You will probably nd that the speaker will wobble with one spike not contacting the oor. Adjust this spike until all four spikes are in contact to the oor.

With the aid of a spirit level move each spike in and out until the loudspeaker is level and siing 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 oors etc. and should be aached in the same manner as the

spikes.

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 inuences the performance of your loudspeakers, please do not use imsy 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 oers beer 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 dierent colours, or oen 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 le 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 le in place for standard installations.

Why Bi-Wire?

intermodulation eects and improves headroom and clarity. To bi-wire, you will need to install two lengths of twin core cable between the amplier and each loudspeaker.

Positioning the Front Loudspeakers

121 - 122 155 - 159

The 155, 156, 157 and 159 models are designed to be oor 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 dierent congurations and play a wide range of programmes before nalising 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 at 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.
