Preparing the EVO4 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 ces the performance of your loudspeakers, please do no sy 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 o ers 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 di
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.

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

I

f your speakers 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.

Positioning the Front Loudspeakers

The EVO4.3, EVO4.4 models are designed to be r standing. We suggest that they are positioned at least 200mm from the rear walls and
700mm from the side walls, facing slightly inwards. The EVO4.1 and EVO4.2 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 a seated listener. As personal taste plays a large role, experiment with
di erent con rations and play a wide range of programmes befor 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

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.

Positioning Surround Loudspeakers

EVO4.S Surround Loudspeakers

The speakers should ideally be sited 600 mm-1.5 metres above the listening position and 2.5-3.5
metres apart, central to the listener and behind the listening position, preferably on a rear wall. If the
listening position is some distance from a rear wall, the speakers may be mounted on opposite side
walls but always behind the listening position.

Ensure that the wall is sound and can support the product. Drill two 5mm holes in the wall 200mm
apart.

Fix a suitable No 8 round head screw
of 5mm protruding from the wall.

Connect the loudspeakers. Align the holes in the mounting brackets over the screw and carefully
lower the unit onto the screws.The speaker should now be securely attached with the spacers resting
against the wall. Now connect the speakers t r.

Setting Up a Home Theatre System

Placement

Front and E ects 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 e
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.

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 ‘ ’ 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 put the A/V r 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 in level 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. Start with the subwoofer volume control set to between 12 o'clock and 3 o'clock.

Delay and LFE Settings

Many A/V 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, but other systems 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 fr
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: Plea

se read the relevant sections of your A/V a r 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 d use rear stage and good localization of
dialogue. If the colours on the loudspeaker terminals do not correspond with those on the r, 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 e
