purchasing Wharfedale. We hope your loudspeakers will give you rewarding listening for many years .
Please read these instructions carefully before installing your Wharfedale loudspeakers.
Before making connections to any part of your sound system make sure the amplifier and all connected
sources are switched off.
When you switch on your system or change sources, set the volume control to minimum and turn up the
level gradually.
DO NOT use your amplifier at full volume. The position of the Volume Control is NOT a reliable
guide as to the maximum volume level or capabilities of your sound system. Playing the system with
extreme high settings of volume and tone controls will result in distorted sound and may damage the
amplifier and loudspeakers.
Preliminaries
Unpacking the Speakers
Carefully remove each loudspeaker from its packing carton. Be especially careful when removing the
polythene bag.
DO NOT attempt to lift the loudspeaker by the polythene bag.
Retain the packing for future use. If you decide to dispose of the packing, please do so safely.
Fitting the Plinth and Spikes (Pacific Evolution 20, 30, 40)
Carefully invert each loudspeaker. Protect the top surface from scratches or damage when the
loudspeaker is in the inverted position. Remove the plinth from the packing and screw it
firmly to the pre-drilled loudspeaker base using the screws provided.
Each loudspeaker is provided with a pair of short spikes and a pair of long spikes. Prepare
the spikes as shown and screw the short spikes into the threads at the front of the plinth.
FRONT
Screw the long spikes into the top caps at the rear of the plinth. Return the loudspeaker to its normal
position taking care not to cause damage with the spikes. When moving speakers, be careful not to let
the spikes pierce objects or cables which may be concealed under the carpet. Never drag loudspeakers.
If you cannot lift them easily, get someone to assist you.
Connections and Terminals
Choosing and Preparing Cables
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 ot coloured
tracer in the case of twin cable.
Split the twin cores to a depth of about 40mm. Caefully strip the insulation
from each end, leaving about 10mm of bare wire. If the cable is stranded,
lightly twist to gather any loose strands.
Crossover Networks
Pacific Evolution front and centre loudspeakers use a specially designed 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.
The Pacific Evolution DFS-20 uses a conventional twin terminal crossover panel.

DO NOT connect loudspeaker terminals to the mains supply.
Ensure that all loudspeakers in the system are correctly wired and are in phase.
DO NOT subject your loudspeakers to excessive cold, heat, humidity or sunlight.
WARNING: To reduce the risk of fire or electrical shock do not expose this product to rain or moisture.
The product must not be exposed to dripping and splashing and no object filled with liquids such as a
vase of flowers should be placed on the product.
No naked flame sources - such as candles - must be placed on the product.
DO NOT place heavy objects on top of loudspeaker cabinets.
NEVER let anyone, especially children push anything into holes, slots or other opening in the case.
If you wish to play your loudspeakers with their grilles removed be careful to protect the drive units from
children and pets.
DO NOT use makeshift stands. Always fit a manufacturer's approved stand according to the instructions
and using the fixings provided. Your dealer will advise you.
DO NOT attempt to dismantle the loudspeaker. There are no user serviceable parts inside and you will
invalidate the warranty.
The rear spikes should now be adjusted.
Loosen the nut and cap and screw the spikes in
or out so that the speakers are stable. The top
surfaces of each loudspeaker should be level
and the same height above the floor.
Now tighten the nut and cap. The illustration
shows the completed assembly.
Stands and Brackets
The Pacific Evolution 8 and 10 are intended primarily for stand mounting, though they can be mounted
on wall brackets or even on sturdy shelves. The quality of loudspeaker stands makes a considerable
difference to the performance of your loudspeakers so do not use flimsy inferior products.
Pacific Evolution Centre Channel Loudspeaker
A set of self adhesive pads is provided. Peel off the backing material and fix a pad close to each corner of
the bottom surface of the loudspeaker.
Pacific Evolution DFS-20 Surround Loudspeaker
Four self adhesive spacers are provided with each unit. Attach one close to each rear corner of the
cabinet. This speaker is designed primarily for wall mounting - please see the separate section on this
topic.

Connecting Loudspeaker Terminals
Unscrew the terminal. Thread the bared end of each cable through the hole in the bottom of the
terminal post. Ensure that there are no loose strands which may touch adjacent terminals. Retighten
the terminal securely. The drawing on the right illustrates the method.
NOTE: When connecting loudspeakers, the cables to left and right channels should be of equal length,
regardless of the distance of the speakers from the amplifier. This applies to front and rear channels.
