However good the loudspeaker,the final results will depend on the acoustic characteristics of the listening room and
the position of the loudspeakers in it. Do not be afraid to experimentwith both position and orientation and make a
point of trying some of the less obvious as well as the more obvious positions. The benefits obtained from the time
spent doing this can be very rewarding. When experimenting, it is preferableto use good recordings or works with
which you are familiar in the concert hall or good quality speech.
The loudspeakers may be mounted on floor stands, sturdyshelves or wall brackets. L-ite satellite speakers are
provided with standard omnimount fixings and suitable bracketsare available as optional extras from your QUAD
dealer.
The loudspeakers should ideally be angled slightly inwardtowards a central listening position. The ideal distance will
be found by experimentation but as a guide the speakersshould be as far apar t fromeach other as each speaker is
from the listener.
If the loudspeakers are mounted on stands they should be placed at least 20cm (8”) fromthe rear wall of the
listening room. Placing the loudspeakers close tothe rear walls will increase the bass response but may introduce
colouration at low and low-mid frequencies. Topreser vethe outstanding polar response of these loudspeakers, the
rear wall should be solid, preferably plastered brick.
As a general rule the centre of the tweeters should be at ear levelto a seated listener. It is not advisable to operate
the loudspeakers across corners, in alcovesor behind furniture.
2
The loudspeaker should be positioned central to the televisionand mounted above or below the screen. Locate the
loudspeaker on a stable flat surface to avoid anydanger of the cabinet moving at high sound levels.
If you mount the unit on top of the television, moveit forward so that the front grilles are level with or slightly in front
of the screen. This will reduce reflections from the screen and the top of the cabinet. If you are using a Plasma or LCD
screen you should place the loudspeaker on a separate shelf or consider wall mounting.

Front Loudspeaker Positioning
Setting levels:
Once the loudspeaker settings have been finalised, put the AVamplifier into its “Test” mode (see instructions supplied
with your processor.)Adjust the levels until all channels are reproduced at equal loudness.
In order to leave the subwoofersome headroom, the volume display should be around at normal listening levels.
To achievethis you may need to adjust the subwoofer output level from your AV processorto compensate.

LFE:
Note:
Low Pass Filter:
Low-level listening
By Ear:
Using an SPL Meter:
This channel was originally an additional bass channel with its own dedicated subwoofer.In practice however, if
any speakers are set to ‘Small’, the LFE channel is combined with the bass fromthose channels and fed into the
subwoofer.When you set the LFE level from your AV processor, use care as the LFE channel contains powerful low
frequencies which, although normal in a cinema, may overload a domestic subwoofer. If, during a programme, you
hear popping or thumping noises from the subwoofer,turn the AV Processor volume level down and back off the LFE
level. If this does not cure the problem, lowerthe subwoofer volume level.
If any channels are set to ‘Small’ the subwoofermust be on when the system is playing otherwise there will be
reduced bass , as well as no LFE.
The low pass filter should be set having regard tothe size and low frequency extension of the main
speakers. The role of the subwooferis to extend the bass response of the system not to increase the overall bass
level. If the loudspeakers are large the LPF should be set low,a value around 75 Hz is a good place to start. With
smaller speakers this can be increased, up to 85Hz for very small bookshelf units. As alwaysthe final value is
determined by listening.
: Our ears are far more sensitive to midrange frequencies (2-5 kHz) than bass frequencies.Very
low bass and especially percussive bass is ‘felt’ rather than heard.At low sound levels bass frequencies appear to
attenuate faster than midrange and treble. As the level increases this bass roll-off decreases and at loud volumes is
negligible. The pioneering work was done in the 1930’s by Fletcher and Munson who produceda series of ‘Equal
Loudness Contours’. Occasionally we may wish to listento a normally loud piece of music at a low level but with
retention of the bass information. The slope control on Quad pre-amplifierscompensates to some extent but there
may be a case for assigning a preset forlow level listening where the subwoofer volume is set somewhat higher and
the LPF is set somewhat lower - as alwaysthis is for individual judgement.
The simplest way to testthe system is to play, at a moderate level, music with deep consistent bass. Switching
the subwoofer in and out of Standby should cause change of the depth of bass, and the ambience will also alter.If
there is a significant change in bass volume, or a noticeable step in the bass response, or an increase in coloration
when the subwoofer is playing, the setupneeds to be refined fur ther.By entering different settings in different
presets, you will be able readily to identify the most favourablecombination.
This is done with a test disc or signal generator and is beyond the scope of this handbook
except to observe that SPL meter settings are weighted‘A’, ‘B’ and ‘C’ - these correspond to the inverse of the
Fletcher-Munson Equal Loudness Contours at 40, 70 and 100dB.For normal listening levels the SPL meter is usually
set to ‘C’ and the response set to slow. If you wish to use this setup methodyou should definitely seek your dealer’s
advice beforehand.

Most of the audiosignal going to the speakers drives thebass units. Where one cable feeds both bass andtreble units,
this heavy bass current can modulate the high frequencies. Using separate cables for treble and bass units reduces
intermodulation effectsand improves headroomand clarity. This isknown as Bi-Wiring. Tobi-wire, you will needto install

If you are not using a subwoofer:
If you are using a subwoofer:
The front loudspeakers are placed on either side of the televisionscreen, 2 to 3 metres apart. The speakers should
be angled slightly so they are aimed towardsthe listeners.
We recommend placing the rear effects speakers in a high position, behind the listener’shead. If the rear or side
walls are a long way from the listeningseat, consider stand mounting the loudspeakers. If the centre loudspeaker is
very high or low, angle it towardsthe listener's ear level. The front faces of the centre and surround loudspeakers
should also be in line as far as possible.
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 subwooferacross a corner boosts the bass but
may impair clarity. The performance of Home Theatre systemscan of tenbe enhanced by using a pair of subwoofers.
Many digital AV Processorsask you to specify the size of speakers in all channels - usually ‘Large’ or ‘Small’.
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.
All Quad L-ite2 loudspeakers must be set to "small". Their bass from those channels will then be diverted into the
subwoofer.Any loudspeakers which are set to‘Large’ will reproduce the full range.
Once the loudspeaker settings have been finalised, put the AVamplifier into its “Test” mode (see instructions supplied
with your processor). Adjust the level of each channel until all channels are reproduced at equal loudness.
You mayneed to adjust the subwoofer output level. Avoid setting too high a level or you will swamp the sound with
bass and may limit the subwoofer’s ability torespond to large bass transients. You should also set a sensible level
going into the subwoofer fromthe AV processor.

Connectors and Cables
Loudspeaker cables
Signal Cables
Before Connecting the Subwoofer
You should ensure that cables which are used with Quad equipmentare properly terminated and appropriate to the
task. This is particularly important with loudspeaker cables and connections. If you are in doubt consult your dealer.
When routing any cables to loudspeakersdo not run them across open floor spaces where they may cause danger to
people and pets. Route them safely,around room boundaries if necessary.
Loudspeaker cables should be carefully prepared. When stripping the insulation, be careful not to cut intothe wire.
Make sure that you collect together all the strands of wire as straywires may cause shorting which could result in
damage or cause a fire.
When estimating the length of loudspeaker cable, provide sufficient to enable access and tidy securing. Some cables
are quite heavy and should be placed so that they do notcause undue strain on the binding posts of the subwoofer.
Signal cables should be properly terminated and fully screened tominimise hum. If you connect your subwoofer via
the low level signal inputs, the cable betweenyour control unit or processor and the subwoofer could be quite long so
screeningis particularly important. Consult your dealer if in doubt.

Switch off your amplifier and all connected source units at the mains.
Unplug the power cords to all system components if necessary.
Make sure the subwoofer is disconnected from the mains and that the ON/OFF switch is OFF.
Before re-connecting your system to the AC power supply, check that all the connections are properly made.
Check that all speaker terminals are done up tightly.
Ensure that there are no strands of wire shorting adjacent speaker terminals.

Checking the AC Power Supply
Fuses
The subwoofer is supplied in versions suitable for connection to 230V,220V, 115V or 100V AC power supplies.
Before connecting to the AC powersupply, check that the voltage range marked on the back corresponds with that of
the supply. Please check with the dealer if you have any doubt as tothe voltage in your area or intend to use the
equipment in regions which use other mains voltages.
The mains supply fuse of the subwoofer is accessible on the rear panel after the IEC mains plug has been removed.In
the rare event that it has broken,you should first check for any obvious cause before replacing the fuse with one of
the correct rating and type. The correct fuse values are:
220 - 240V (UK, Korea, etc.) T 4 AL 20mm Slow Blow
100- 120V (USA, Japan, etc.) T 8 AL 20mm Slow Blow
Switch off the equipment and remove the connection to the mains power outletbefore changing the fuse.
Positioning the Subwoofer
Although the unit may be placed almost anywhere in the room, werecommend that it be placed in front of the listener
and as central to the listening position as possible. As the subwooferis a powered unit there should be a mains outlet
within easy reach. The subwoofer should not be operatedwithin 450mm of a conventional CRT television set as the
drive unit magnet may distort the picture. Remember that there should be a line of sight betweenthe listening
position and the front of the subwoofer otherwise the remotefunctions will not be operable.
We suggest you initially position the subwooferabout 20cm (8 inches) from the wall. Placing the unit close to the wall
will enhance the bass; placing it across the corner of the room will increase the bass further, possibly at the expense
of clarity. Do not place the subwooferclose to surfaces or objects that may rattle. The floor under the subwoofer
should be sound with no loose floorboards, etc.
You should expectto experiment with a variety of locations and sources before making a final decision.

Connecting to a Digital AV Processor
Stereo Line Level Connections
Connect a stereo RCA phono cable from the line
output of the preamp to the Subwoofer line inputs.
If your AV processorhas a line level or LFE subwoofer output you should use this connection. You will need to
purchase a single screened RCA phono lead from your dealer.Connect this lead to the Left line input of the Subwoofer
as shown below.
Stereo line level connections will be necessary:
where there is no dedicated single subwooferoutput, but where there is either a stereo subwoofer line output or a
separate preamp output.
where there is a preamplifier line output, or if an integrated amplifier,a pre/main link that can be separated.
The output must be controlled by the system volume control- a tape output is not suitable. If you are in doubt, consult
your dealer.

Delay and LFE Settings
Expanding the System
The purpose of delay is to enable surround and dialogue informationto arrive at the listener’s ears at the same time
as the Front channels, evenwhen the listening seat is in a non-ideal position.
If the listening position is equidistant from the Frontand Rear speakers, a low delay setting should be set.
The closer the listener is to the Rear speakersthe higher should be the delay setting used,
If the Centre speaker is level with (or slightly behind) the Frontspeakers, set the delay to zero. If the
Centre speaker is forward of the Frontspeakers, increase the delay.
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 frequencies can overload domestic loudspeakers.
If you hear popping or thumping noises coming from the front loudspeakersor subwoofer, immediately turn the AV
Processor's volume level downand then back of f the LFE level.This should cure the problem. If it does not, back off
the volume level at the subwoofer(if you are using one) until the problem disappears.
Please read the relevant sections of your AVamplifier manual and familiarise yourself with the various issues. If you
are unsure, consult your dealer for help.
Dolby Labs, DTS and THX offer 6.1and 7.1 formats which extend the 5.1principle by adding one or two extra rear
effects channels. Although the precise configuration of these systems will depend on the capabilities of your
processor and you should be guided by those instructions, we wouldmake some observations.
For most 6.1 and 7.1 formats the listening seat should not be tooclose to the rear wall.
Optimising the time delay so that information from all speakersarrives at the listening seat coherently is critical if the
benefits of these systems are to be fully realised. THX adjustments in particular need to be followedto the letter.

Speaker Level connections
You will need two screened RCA‘Y’ adaptors and two single RCA phono cables.
Remove the Pre-Main links on your amplifier.Connect the socket (common) of an RCA ‘Y’ adaptor to one of the mono
cables. Connect one leg of the ‘Y’ adaptor to the Left Channel Pre Out socket on the amplifier and the other leg to the
Left Channel Main In socket. Connect the remaining plug on this combination to the Left Channel Line Level Input on
the sub-woofer.Repeat this for the Right Channel.
The High Level speaker connections should be used only if youramplifier does not have a line level subwoofer or
preamp output. You will need twoextra twin core cables.
Using one of the additional twin core cables, connect the Left Speaker Terminals on the subwooferto the Left speaker
terminals of the amplifier.Connect the Red (+) speaker terminal on the amplifier to the Red (+) terminal on the
subwoofer.Connect the Black (-) speaker terminal on the amplifier to the Black (-) terminal on the subwoofer. Now
connect the Right Speaker terminals on the subwooferto the Right speaker terminals of the amplifier.
Method B:Youwill needtwo stereo (orfour single)screened RCAcables.
Connect a Stereo cable from the Line Level Inputsof the subwoofer to the Pre Out sockets of the amplifier. Connect a

Choosing and Preparing Loudspeaker Cable
Specialist audio cable will usually offer better performance than general purpose 'bell' or 'zip' wire. Audio cable is
polarised, with two cores of different colours, or often, in the case of twin cable, a coloured tracer or ridge along one
wire to indicate polarity.Choose a cable of suitable diameter - cable that is too thin will limit the dynamics of the
sound and may impair the bass response. Split the twin cores to a depth of about 25mm. Carefully strip the insulation
from each end, leaving about 7mm of bare wire. If the cable is stranded, lightly twist to gather anyloose strands.
Note that the positive (+) terminals are locatedat the right.
Use an equal length of twin core speaker cable for each channel, and prepare the
ends as described above. Unscrew each speakerterminal. 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. Retightenthe terminal
securely.

Switch off your amplifier and all connected source units at the mains.
Unplug the power cords to all system components if necessary.
Before re-connecting your system to the AC power supply, check that all the connections are properly made
Check that all speaker terminals are done up tightly.
Ensure that there are no strands of wire shorting adjacent speaker terminals.
All loudspeakers in this series use biwired crossovernetworks
for improvedfidelity and low inser tion loss.
The crossover networkseparates the treble and bass networks
into two distinct sections, each connected by a dedicatedpair
of terminal posts. This enables the treble and bass components
to be separately driven for optimum performance. The upper
pair of terminals is connected to the treble networkand the
lower pair to the bass network.
As supplied, the treble terminal pair is connected to the bass
terminal pair by removable metal straps. These should be left in
place for standard installations.

Your subwooferis most likely to be used with two typical programme sources, music and movies. The setup for these
two very different sources may be different if best results are to be achieved.Please read these setup notes in
conjunction with your processor and speaker manuals.
Listening rooms are not ideal. Most rooms are reverberantwith some parallel walls. Because of room geometry and
construction there will be areas with severe peaks at some frequencies and severetroughs at others. If you site
loudspeakers in such areas the response will be highly non-linear.With subwoofers this situation is exacerbated by
the fact that it is easier to treat high frequency irregularities by the use of drapes, soft furnishings etc., but very hard
to do the same at bass frequencies due to the very long wavelengths- at 40 Hz the wavelength is almost 9 metres.
To help locatestanding waves in your listening room, one idea is to sit in the listening seat and recruit a friend with a
deep voice to speak as he moves aroundthe area where you propose to site your subwoofer - you will soon find out
where to site it! Where the voice sounds most natural is a good place to start.
The low frequency response of the subwooferand its blend with the main loudspeakers is thus profoundly affectedby
positioning. Although bass is enhanced by walls or corners, so often is coloration. As the drive unit faces downward,
the floor will influence the sound. The surface under the subwoofer should be stable and unobstructed. If the carpet
is very thick, consider placing the subwoofer on a solid surface such as a marble slab.
if you place the subwoofer where it amplifies the irregularities
of the room or the main speakers the result will be bloated, coloured bass. If acoustic guitar and male voicesounds
coloured when the subwoofer is operating and less coloured when in standby,you need to address the positioning
first before adjusting any controls
Make sure that all loudspeaker channels are connected in phase. Nothingis more cer tain to
defeat a Home Cinema or Stereo setup involvinga subwoofer than one(or more) channels being out of phase.
In Stereo, if there is a doubt about the way the loudspeakersare connected, check their phasing by playing a mono
source - the sound should appear from a point midwaybetween the two loudspeakers. If this position is indefinite,
reverse the connections to one of the loudspeakers.Correctly connected loudspeakers give a definite centre sound
source with fuller bodied tenor and bass registers.
Phase at very low frequencies is not straightforward to detect.Initially we suggest
you temporarily set the low pass filter to‘of f’ and the phase to0º and play some bass heavy music in Stereo through the
main speakersand the subwoofer.From the listeningposition, switchthe phase between0º and 180º. The setting which
appears to give the greater bass output is correct. Now followthe instructions below for setting the low pass filter.
All setting up of the subwoofer should be performed with tone controls and filters set ‘flat’.

Setting the Phase of the Subwoofer:
Listening Rooms and Subwoofer Positioning:
Home Cinema Systems
Low Pass Filter: If you are using a digital AVprocessor the initial setting should be ‘OFF’ as the processor will have its
own bass management system.
Most digital AV Processors ask youto specify the size of speakers in the various channels. These are usually ‘Large’ or
‘Small’. This sets the bass management for the system. Unless your loudspeakersare large floor standing units, you
should choose 'Small' for the Frontchannels, as the subwoofer is going to be better at providing clean, deep bass.
Choose 'Small' for the surround channels and also for the Centre channel, so that anybass from these channels will
be directed to the subwoofer.Set the ‘Subwoofer’ option on the processor to 'On’ or 'Yes'.
After experimenting with various sources you mayneed to adjust the LPF settings. The goal is to ensure the subwoofer
blends seamlessly into the sound stage. Setting the subwooferto Standby should reduce the bass extension, not
change the bass level - as always personal tasteplays an important par t.
