Positioning Your Loudspeakers  
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 further 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. 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 different configurations and play a wide  
rangeofprogrammesbeforefinalisingthepositionofyourspeakers.  
ConventionalLoudspeakers  
Pacific Evolution 20, 30 and 40 are designed to be floor standing. We suggest you position them at  
least200mmfromtherearwallsand700mmfromthesidewalls, facingslightlyinwards. ThePacific  
Evolution 8 and 10 should ideally be stand or wall mounted though they may be placed on a rigid  
shelf. The bass extension will improve if these speakers are operated closer to the rear walls. A useful  
ruleofthumbisthatthelistenershouldbeasfarfromtheloudspeakersastheyarefromeachother.  
PacificEvolutionCentreLoudspeaker  
This loudspeaker should be positioned centrally  
between the loudspeakers close to the television and  
mountedeitheraboveorbelowthescreen.  
The loudspeaker should be located on a stable flat  
surface to avoid any danger of the cabinet moving  
when it is vibrated by high sound levels. If you mount  
theunitontopofthetelevision,moveitforwardsothat  
the front grilles are level with or slightly in front of the  
screen. This will reduce reflections from the screen and  
thetopofthecabinet.  
Althoughyoucanplacethecentrechannelloudspeaker  
under the TV monitor, this should always be regarded  
as second best. The preferred position is always above  
themonitor,asshown.

ThePacificEvolutionDFS-20SurroundLoudspeaker  
Connect the cable to the speaker. The speaker 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 loudspeakers  
maybemountedonoppositesidewallsbutalwaysbehindthelisteningposition.  
Ensure that the wall is sound and can support the product. Drill two 5mm holes in the wall 160mm  
apart and horizontally aligned. Fix a suitable No 8 round head screw firmly into each hole using  
appropriatewallplugs. Leaveastubof5mmprotrudingfromthewall.Aligntheholesinthemounting

FrontandEffectsChannels  
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  
whichbetiringtolistentoandmaylimitthesubwoofer’sability  
to respond to large bass transients. You should also set a  
sensiblelevelgoingintothesubwooferfromtheAVprocessor.  
Thefrontloudspeakersareplacedoneithersideofthetelevision  
screen, 2 to 3 metres apart. The speakers should be angled  
slightlysotheyareaimedtowardsthelisteners.  
As the rear surround channels are the ‘effects’ channels the  
reproduced sound should be as room filling as possible. We  
recommendplacingthespeakersinahighposition, behindthe  
listener’s head and angled towards the listener. If the rear wall  
ismorethan1metrebehindthelisteningseat,positiontheunits  
on the side walls. If the walls are a long way from the listening  
seat,considerstandmountingtheloudspeakers.  
DelaySettings  
ManyAVprocessorsfeaturedelaysettings.Thepurposeofdelay  
is to enable surround and dialogue information to arrive at the  
listener’s ears at the same time as the Front channels, even  
whenthelisteningseatisinanon-idealposition.  
Most of the dialogue comes from the centre loudspeaker.  
Speech should appear to originate from the actors’ mouths.  
Operating height is important. Ideally the front and centre  
channelspeakersshouldbeatthesameheight. Forthisreason  
the centre channel speaker is best operated on top of the  
television monitor. The front faces of the centre and surround  
loudspeakersshouldalsobeinlineasfaraspossible.  
Rear Delay: If the listening position is equidistant from the  
Front and Rear speakers, a low delay setting should be set. The  
closer the listener is to the Rear speakers the higher should be  
thedelaysettingused,  
Centre Delay: If the Centre speaker is level with (or slightly  
behind) the Front speakers, set the delay to zero. If the Centre  
speakerisforwardoftheFrontspeakers,increasethedelay.  
Subwoofer  
As the ear is unable to detect the direction from which deep bass  
originates, this allows you freedom to position the unit. Varying  
the distance from the wall alters the bass. Placing the subwoofer  
acrossacornerbooststhebassbutmayimpairclarity.  
LFE  
InthecinematheLowFrequencyEffectschannelisanextrabass  
channel with its own subwoofer and not a regular subwoofer  
channel. In domestic systems the LFE channel typically feeds  
into the subwoofer. Where no subwoofer is used, the LFE signal  
is combined with Front Channel information. When you set the  
LFE level at your AV processor, use care as the powerful low

SettingLoudspeakerSizes  
Many digital AV Processors require you to specify the size of  
speakers inallchannels.Theseareusually‘LargeorSmall’.  
Always choose 'Small' for the Surround channels and Centre  
channelwhetheryouareusingasubwooferornot.  
If you are not using a subwoofer: Set the Front Speakers to  
Large’. Set the ‘Subwoofer’ option on the processor to 'Off' or  
No'. TheFrontchannelswillnowreceiveallthesystembass.  
Please read the relevant sections of your AV amplifier manual  
and familiarise yourself with the various issues. If you are  
unsure,consultyourdealerforhelp.  
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. Bookshelf speakers should be set to ‘Small’, large  
floorstandingunits maybesetto‘Large’.  
Phase  
A Home Theatre system should have a precise front stage, a  
diffuse rear stage and good localisation of dialogue. If the  
colours on the loudspeaker terminals do not correspond with  
thoseontheamplifier, thesoundwillappearpoorlyfocussedor  
‘out of phase’. For this reason it is essential that the speakers  
areconnectedaccordingtothewiringdiagramsinthismanual.

Once the loudspeaker settings have been finalised, put the AV
