BRITAIN'S MOST FAMOUS LOUDSPEAKERS

SETTING UP TWO SUBWOOFERS

General notes

Site the subwoofers so that they enhance the system bass
response but do not cancel each other out.

! A well-sited pair of subwoofers for stereo applications

will be adequately sited for Home Cinema
applications.

! A second subwoofer raises the bass output level 6dB

when operating in Home Cinema but not in Stereo.

! Both subwoofers should be in line of sight to the

listening seat as both answer to one remote handset.

! When operating two subwoofers, do all setups and

operations on one handset When allocating presets
make sure that the same preset (e.g. Home Cinema on
preset 1) is allocated to each subwoofer.

Home Cinema:

! As AV Processors produce a common subwoofer

channel, considerations of Left and Right do not
apply, but with spaced subwoofers each helps to fill in
the troughs caused by in-room standing waves,
smoothing the bass and giving the sound greater
intensity, ‘air’ and depth.

! Set up the position of each subwoofer separately with

the other one switched off. After you have set both
subwoofers up, reduce the front panel volume level of
each subwoofer by 3 points. Complete the final
adjustment with both subwoofers switched on. You
may need to make some small adjustments to the
position of each sub for best results. We suggest you
enter this final setting as a Home Cinema preset.

Stereo:

! Each subwoofer should be located as near as possible

to its partnering loudspeaker. The smaller the main
speakers, the more necessary this becomes.

! It is easier to set up each subwoofer with a mono

source playing through one channel with the other
channel turned off.

! Complete the adjustment by ear using a mono source

with both channels and subwoofers operational. We
suggest you enter this setting as a Stereo preset.

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 with regard to any recycling regulations in your area.

Retain the instructions. If you pass a product to a third party, please
include the instructions.

Fitting the Plinth and Spikes (Models 9.4, 9.5, 9.6 only)

Carefully invert each loudspeaker. Protect the top surface from
scratches or damage when the loudspeaker is in the inverted position.

Each loudspeaker is provided with four spikes. Prepare the spikes as
shown and screw the spikes into the threads on the plinth. Return the
loudspeaker to its normal position taking care not to cause damage with
the spikes.

Crossover Networks

Most speakers in the Diamond 9
series use a specially designed bi­wireable 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 D9.0 compact monitor, the D9.CC compact Centre Channel speaker
and the D9.SR use essentially the same circular section crossover panel.
These are illustrated below.

The D9 DFS uses a crossover network panel built into the speaker’s rear
wall. This is illustrated on Page 4.

None of the abovementioned loudspeakers are bi-wireable.

D9.SR D9.0 & D9.CC

Choosing and Preparing Cables

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

Adjusting the Spikes: Loosen the nut. Screw
each spike in or out so that the speakers are
stable. The top surfaces of each loudspeaker
should be level and the speakers should be the
same height above the floor.

When the speakers are in their final positions,
tighten all the nuts.

Stands and Brackets

The 9.1, 9.2, and 9.3 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 influences the performance of your
loudspeakers so do not use flimsy products.

The Diamond 9.0 may be stand or wall mounted. The rear panel has a
threaded insert for attaching a pair of suitable wall brackets.

Centre Channel Loudspeakers

Each centre channel loudspeaker is supplied with two sets of mounting
feet. By using a 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.

Surround Loudspeakers

These speakers are designed primarily for wall mounting, though they
may be stand or shelf mounted if required. Please see Page 5

Specialist audio cable 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 or
coloured tracer in the case of twin 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 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. Re-tighten the
terminal securely. The drawing on the
right illustrates the method.

NOTE: When connecting loudspeakers,
the cables to left and right channels
should ideally be of equal length,
regardless of the distance of the
speakers from the amplifier.

OPERATING YOUR SUBWOOFER

Remote Handset

All control functions are carried out using the remote handset.

Installing batteries

The handset operates on two LR6 (AA)
batteries which are supplied The battery

SUBWOOFER CONTROL

Operation - Controls and Functions

Control functions are carried out using the remote handset. To operate,

the handset must be point at the subwoofer and be in direct line of sight.

Standby: The Standby key brings the subwoofer in and out of Standby.

The drawing below shows a typical front panel display during operation.

The preset light will not light if no preset has been set up or if a preset
has been over-ridden.

In Standby mode all the lights on the subwoofer front panel are
extinguished. The rear panel light remains on to show the unit is
powered.

compartment is located at the rear of the
handset. Unwrap the batteries and slide the
cover off the handset. Place the batteries in
the handset, the correct orientation is shown
on the diagram. When the batteries are
installed, replace the cover.

Switching on the Subwoofer

Check that all the connections to the
subwoofer have been properly made and
that the system volume control is at
minimum. Plug the supplied power cord into
the mains socket on the rear panel. Plug the
mains plug into the wall socket and switch
the power on. Now switch the subwoofer on
with the rest of your system. The subwoofer
on/off switch has a rocker action; press the
upper part to switch the equipment on and
the lower part to switch it off. When switched
on the light above the power switch will glow
and the subwoofer will be operational.

Volume: Press the Volume + key to increase the volume level. Press the
Volume - key to decrease the volume level of the subwoofer. The volume
range on the front panel display varies from 00 (minimum) to 99
(maximum).

Low Pass Filters: Pressing the appropriate filter key will select the
frequency at which the subwoofer rolls off. The filter has steps at Off and
35Hz-85Hz in 10 Hz increments. When ‘OFF’ is selected the subwoofer
operates over its full designed range. Pressing other keys lowers the
maximum operating frequency. The Low Pass Filter value should be
chosen having regard to the nature of the Front speakers and
programme material. Follow the Setup Notes on Page 6 and the
instruction manual of your AV processor (if used) for more guidance.

Phase: This key toggles the subwoofer between 0º and 180º phase shift.

Presets: Four different settings of level, frequency and phase can be

stored. Pressing and holding any of the preset keys on the remote for 3
seconds will cause the current settings to be stored in that preset. The
display will show the preset number then flash the preset number once
to show it has stored the preset.

To change from one preset to another, press a preset key on the remote
for less than 3 seconds to recall the settings of that preset. The display
will show the preset number:

If you select a preset and then alter any aspect of the setup, the preset
light will extinguish (as the setup no longer matches the preset).

Note: When brought out of standby for the first time, the unit will display
the factory presets. Thereafter, bringing the unit out of standby will
revert it to the operational state last used. If you switch the power on and
off at the rear panel while the unit is in standby, the unit will power up to a
normal operating state (i.e. not in standby). To enter standby, again
press the Standby key.

SETTING UP YOUR SUBWOOFER

General Notes

Your subwoofer is 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.

All setting up of the subwoofer should be performed with tone controls
and filters set ‘flat’.

Listening Rooms and Subwoofer Positioning:

Listening rooms are not ideal. Most rooms are reverberant with some
parallel walls. Because of room geometry and construction there will be
areas with severe peaks at some frequencies and severe troughs at
others. These peaks and troughs are called ‘standing waves’ and 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 locate standing 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 around the area where you propose to site your subwoofer - you
will soon find out where not to site it! Where the voice sounds most
natural is a good place to start.

The low frequency response of the subwoofer and its blend with the main
loudspeakers is greatly affected by 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 thick,
consider placing the subwoofer on a solid surface such as a marble slab.

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 flat surface to avoid any

cabinet movement at high sound

levels. If you mount the unit on top of

the television, move it forward so that

the front grille sits slightly in front of

the screen. This will reduce sound

reflections from the screen and the top

of the cabinet.

The D9 CS and the D9 CM are supplied

fitted with mounting feet which

support the cabinet in a horizontal

position. Four extra feet are supplied to

enable you to tilt the cabinet up or

down so that the speaker points

directly at the listening position. This

facility is particularly useful where the

Centre speaker is mounted under the

screen.

NOTE: All Diamond 9 bookshelf and floorstanding loudspeakers are

THE HOME CINEMA ENVIRONMENT

The diagrams below illustrate some typical Home Cinema room layouts.

System with Rear Mounted D9 DFS Surrounds System with Side Mounted D9 DFS Surrounds System with D9 SR Surround Speakers

magnetically shielded so they may be positioned close to TV screens
and monitors with no ill-effects or colour distortion.

D9 DFS 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 t he listeni ng positio n,
preferably on a rear wall.

If the

220 mm

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 220mm apart. Fix a
suitable No 8 round head screw firmly
into each hole using appropriate wall
plugs. Leave a stub 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 to the
amplifier.

Note: As an alternative, the D9 DFS can be shelf or
stand mounted. The badge on the D9 DFS can be
rotated to match the orientation of the loudspeaker.

D9 SR Surround Loudspeakers

Before mounting the loudspeakers, establish the
location using the same criteria as for the D9 DFS.
Ensure the wall is sound and can easily support the
weight of the loudspeakers.

The D9 SR is supplied with four mounting feet for shelf
or stand mounting. In addition the terminal panel has a
built in mounting slot for wall fixing.

Wall mounting the D9 SR: Ensure the wall is sound
and can easily support the weight of the loudspeakers. Drill and fix a No.
8 screw and suitable wall plug at each chosen location. The screw should
protrude about 5mm from the wall. Connect the cable to the speaker.
Align the keyhole slot over the screw. Pull gently down to secure the
speaker.

Note: When using spiked feet take care not to drag the subwoofer and be
careful not to pierce objects or cables which may be hidden under
carpets, etc. Spikes are not suitable for use with stone floors and can
cause damage to wood floors, so consider carefully before deciding
which feet to use.

INSTALLATION

Positioning the subwoofer

Although the unit may be placed almost anywhere in the room, we
recommend that is placed in front of the listener central to the listening
position. There should be a mains outlet within easy reach. There should
be a line of sight between the listener and the front of the subwoofer
otherwise the remote functions will not work.

W

e suggest you initially position the subwoofer about 20cm (8 inches)
from the wall. Placing it close to the wall will increase the bass; placing it
across a room corner will increase the bass further, possibly at the
expense of clarity. Do not place the subwoofer close to surfaces or
objects that may rattle. The floor under the subwoofer should be sound.

Subwoofer as shown below.

Stereo Line Level Connections

Stereo line level connections will be necessary where there is no
dedicated single subwoofer output, but where there is either :

! A stereo subwoofer line output or a separate preamp output.
! In stereo systems where there is a suitable 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.

Stereo Connections: Connect a stereo RCA phono cable from the line
output of the preamp to the Subwoofer line inputs.

PRELIMINARIES CONNECTING THE SW 150

Open the carton and remove all the top packing pieces. Lift the
subwoofer out taking care not to damage the cabinet. When lifting the
unit from the carton support it from the bottom. DO NOT attempt to lift
the subwoofer out of the carton using the polythene bag. The unit is

to any recycling regulations in your area.

Please retain the user manual and the purchase receipt for future
reference. If you transfer this equipment to a third party, please ensure all
the instructions are passed on with the product.

Power Connections

This subwoofer is factory set to operate from the mains voltage marked

on the amplifier panel. Before connecting check this voltage is correct for
your mains supply.

! 230 volt products - 220 volts to 240 volts
! 115 volt products - 110 volts to 120 volts

If you move to an area with a different mains supply, consult your
Wharfedale dealer for advice.

Line Connections to an A/V Processor

Your subwoofer has been designed for optimum performance with a
Digital processor. If your AV processor has 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.

Alternatively, you may use a split mono lead from the processor to both
inputs of the subwoofer. In this case the input level at the subwoofer will
be slightly higher.

Stereo Line Output Connections

If your amplifier has a spare preamplifier output or a stereo sub-woofer
output, connect the sub-woofer as shown. You will need a stereo
screened RCA phono cable.

Pre Out - Main In Connections for Stereo Amplifiers

If you use a stereo pre and power amplifier, or a stereo amplifier where
the pre and main amplifier can be separated, connect the sub-woofer as
shown. There are two alternative methods.

A: 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

the Pre Out sockets of the amplifier. Now connect a second Stereo cable
from the Line Level Outputs of the sub-woofer to the Main In sockets of
the amplifier. The sub-woofer is now inserted within the system loop.

Speaker Level Connections

The high level Speaker connections should be used only if your amplifier
does not have a line level subwoofer output. In this connection the
subwoofer is fed together with the Front loudspeakers. For this you will
need two extra twin core cables.

If your speakers are bi-wired: You should ensure that you connect the
subwoofer to the BASS terminals ONLY.

Choose a good quality audio
speaker cable of reasonable size.
Avoid using cheap ‘bell’ or ‘zip’
cables. Audio speaker cable has a
polarity stripe or rib along one
conductor to simplify connecting
your speakers.

Split the cable at each end to a
depth of 30mm. Strip about 7mm
of insulation from each end and
lightly twist to gather the wire
strands.

The Speaker Level connectors are screw terminals located on the control
panel. Unscrew a terminal and insert the cable into the hole at the base.
Re-tighten the terminal securely. Make sure that the terminal grips the
bare wire and there are no loose strands which could touch adjacent
terminals.

There are two methods of connecting the subwoofer.

A: Using one of the additional twin core cables, connect the Left Speaker

Terminals on the sub bass unit to the Front Left speaker terminals on 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 subwoofer to the Front Right
speaker terminals of the amplifier.

OPERATION

Positioning the Unit

Although the unit may be placed almost anywhere in the room, even
behind the sofa or the TV set, we recommend that it be placed in front of
the listener and as central to the listening position as possible. The
subwoofer should not be operated within 450mm of a television set as
the drive unit magnet may distort the picture.

We suggest you position the subwoofer about 20cm (8 inches) from the
wall. A position close to the wall will enhance the bass; placing it across a
room corner will increase the bass further, possibly at the expense of
clarity. Experiment with a variety of locations and sources before making
a final decision. Ensure there is a mains outlet within easy reach.

The bass port is mounted underneath the subwoofer and moves a lot of
air at high volume, so make sure the floor is sound. The subwoofer is
front-firing so do not place it behind surfaces or objects that may rattle.

Your system will perform best if there is a clear line of sight between the
subwoofer and the listening position.

SETTING UP

! Set the subwoofer power switch to OFF.
! Turn the system Volume Control to minimum.
! Re-check all system connections.
! Connect the supplied subwoofer power lead to the IEC power socket

on the subwoofer and connect the mains plug into the wall socket.

When routing any cables to loudspeakers do not run them across
open floor spaces where they may cause danger to people and
pets. Route them safely, around room boundaries if necessary.

! Switch on the mains power.
! Set the subwoofer volume control to the mid position (12o'clock)

before proceeding.

Page 8

Fine Tuning

Switch on the subwoofer power switch and check that the power
indicator on the front of the cabinet glows. Now switch on the system.
Play a programme with extended bass and set the system volume to a
reasonable level. Adjust the subwoofer volume control to produce the
desired level of bass. Do not overdo things!

PHASE SWITCH: If the bass is indistinct or lacks depth, the Phase switch
may need adjustment. Set the switch to 0º and listen carefully to some
music with extended bass. If there is insufficient bass output from the
sub-woofer set the Phase switch to 180º. Select the position which
produces the most natural, extended bass.

LOW PASS FILTER ADJUSTMENT. This adjusts the blend between the
subwoofer and the main speakers. and enables the system to be set up
for optimum bass performance. The higher settings are for use with
small bookshelf loudspeakers, the lower settings for large floorstanding
models. If you choose too low a setting with small speakers, there will be
a ‘hole’ in the bass response; too high a setting with large speakers will
result in the upper bass becoming bloated.

AUTO SWITCH. In normal mode the subwoofer is permanently on. This
may result in low level hum or noise from the subwoofer if the rest of the
system is switched off and the subwoofer is left switched on.

Setting the
AUTO switch to ON will automatically turn the subwoofer on when a
signal is detected at any of the inputs and turn it off (Standby Mode) after
a period of inactivity. We recommend that the AUTO switch be set to ON
for normal operation.

In AUTO mode the indicator on the front of the subwoofer will glow RED
when the unit is in Standby mode and GREEN when operational. If your
subwoofer is disconnected from the mains power, or the Power switch is
“Off”, the indicator will be extinguished.

When the system is not in use for extended periods, we suggest you
switch off the subwoofer to protect it from switching noises caused by
domestic appliances, etc.

Always turn the main volume control to minimum when you switch the
system on or off.

THE HOME THEATRE ENVIRONMENT

As the ear is unable to detect the direction from which deep bass
originates, this allows freedom in positioning the subwoofer. Varying the
distance from the wall will alter the amount of bass. Some prefer to place
the subwoofer against a corner of the room. This arrangement gives
more bass at the possible expense of clarity.

Loudspeaker Sizes

Many digital AV Processors require you to specify the size of speakers in
the various channels. These are usually ‘Large’ or ‘Small’. Unless your
loudspeakers are large floor standing units, choose 'Small' for the Front
channels, as the subwoofer will be better at providing clean, deep and
louder bass. Choose 'Small' for the other channels so that bass from
these channels will be directed to the subwoofer. Set the ‘Subwoofer’
option on the processor to 'On’ or 'Yes'.

Setting Levels

Once the loudspeaker settings have been finalised, put the AV amplifier
into its “Test” mode (see instructions supplied with your processor.)
Adjust the levels until all channels are reproduced at equal loudness.

You may need to adjust the subwoofer output level. Avoid setting too
high a level or you will swamp the sound with bass which be tiring to
listen to and may limit the subwoofer’s ability to respond to large bass
transients. Set a sensible level going into the subwoofer. The subwoofer
volume control should be between 12 o’clock and 3 o’clock .

LFE

The Low Frequency Effects channel was designed as an additional bass

channel with its own dedicated subwoofer. In practice however, if all the
speakers are set to Small, the LFE channel will be combined with the bass
from other channels and all this feeds into the subwoofer. When you set
the LFE level from your AV processor, use care with this setting as the LFE
channel may contain powerful low frequencies which, although normal in
a cinema, may overload a domestic subwoofer.

If, during a programme, you hear popping or thumping noises coming
from the subwoofer, immediately turn the AV Processor's volume level
down and then back off the LFE level. If this does not cure the problem,
back off the volume level at the subwoofer.

Please read the relevant sections of your AV amplifier manual and
familiarise yourself with the various issues. If you are unsure, consult
your dealer for help.

SETTING UP TWO SUBWOOFERS

Two subwoofers offers considerable advantages. Points to note are:

! A well-sited pair of subwoofers for stereo applications will be

adequately sited for Home Cinema applications.

! A second subwoofer raises the bass output level 6dB when

operating in Home Cinema but not in Stereo.

HOME CINEMA: Although AV processors have one subwoofer channel,
properly spaced subwoofers help to fill in troughs caused by standing
waves, smoothing the bass and giving it greater intensity.

STEREO: Each subwoofer should be located as near as possible to its
partnering loudspeaker. The smaller the main speakers, the more
necessary this becomes.

HOME CINEMA SETUP

Front And Effects 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 are
aimed towards the listeners.

As the rear surround channels are the ‘effects’ channels the reproduced
sound should be as room filling as possible. We recommend placing the
speakers in a high position, behind the listener’s head. If the rear wall is
more than 1metre behind the listening seat, position the units on the side
walls. If the walls are a long way from the listening seat, consider stand
mounting the loudspeakers.

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 channel speakers should be at the
same height . For this reason the centre channel speaker is best operated
on top of the television monitor. 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, this allows you 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 Home Theatre systems can often be enhanced by
using a pair of subwoofers.

Setting Loudspeaker Sizes

Many digital AV Processors require you to specify the size of speakers in
all channels. These are usually ‘Large’ or ‘Small’.

The D9 CM centre channel speaker should be set to ‘LARGE’. The other
centre channel speakers and the surround channel speakers should be
set to ‘SMALL’ whether you are using a subwoofer or not.

If you are not using a subwoofer: 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.

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 floor standing units may be set to ‘Large’.

Setting Levels

Once the loudspeaker settings have been finalised, put the AV amplifier
into its “Test” mode (see instructions supplied with your processor).
Adjust the level of each channel in turn until all channels are reproduced
at equal loudness.

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 which is 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 AV processor.

Delay Settings

Many AV 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.

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 the delay setting used,

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 Frequency Effects channel is an extra bass
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 frequencies can overload domestic
loudspeakers.
If you hear popping or thumping noises coming from the front
loudspeakers or subwoofer, immediately turn the AV Processor's
volume level down and then back off 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 AV amplifier manual and
familiarise yourself with the various issues. If you are unsure, consult
your dealer for help.

Pre Out - Main In Connections

If you use a separate stereo pre and power amplifier, or an amplifier
where the pre and main amplifier can be separated, connect the sub­woofer as shown. There are two alternative methods.

A: 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 subwoofer. Repeat this for the Right Channel.

B: You will need two stereo (or four single) screened RCA cables.

Connect a Stereo cable from the Line Level Inputs of the subwoofer to
the Pre Out sockets of the amplifier. Now connect a second Stereo cable
from the Line Level Outputs of the sub-woofer to the Main In sockets of
the amplifier. Make sure that the Right and Left Channels are not mixed
up! The sub-woofer is now inserted within the system loop.

Speaker Level Connections

The high level Speaker connections should be used only if your amplifier
does not have a line level subwoofer output. In this connection the
subwoofer is fed together with the Front loudspeakers. For this you will
need two extra twin core cables.

Choose a good quality audio speaker
cable of reasonable gauge. Avoid
using cheap ‘bell’ or ‘zip’ cables. Audio
speaker cable has a polarity stripe or
rib along one conductor to simplify
connecting your speakers.

Split the cable at each end to a depth of
25mm. Strip about 7mm of insulation
from each end and lightly twist to
gather the wire strands.

The Speaker Level connectors are
screw terminals located on the control
panel. Unscrew a terminal and insert
the cable into the hole at the base. Re­tighten the terminal securely. Make
sure that the terminal grips the bare
wire and there are no loose strands
which could touch adjacent terminals.

There are two methods of connecting the subwoofer:

A: Ensure the Front loudspeakers are correctly connected.

Using one of the additional twin core cables, connect the Left Speaker
Terminals on the sub bass unit to the Front Left speaker terminals on 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 subwoofer to the Front Right
speaker terminals on the amplifier.

B: Alternatively you may connect the subwoofer to the Front speakers.

If your speakers are bi-wired: You should ensure that you connect the

subwoofer to the BASS terminals ONLY.

When routing any cables to loudspeakers do not run them across open
floor spaces where they may cause danger to people and pets. Route
them safely, around room boundaries if necessary.

Connect these speakers as shown below. The Centre channel speaker
may be connected as shown, or bi-wired.

Choose a suitable length of twin core speaker cable for each channel, and

prepare the ends. Unscrew each terminal a few turns.

Connect the red, positive (+) terminal of the Left loudspeaker to the
corresponding red, positive (+) amplifier terminal. Connect the black,
negative (-) terminals similarly. Tighten the terminals securely. Repeat
this procedure for the Right Channel.

Positioning the Front (stereo) Loudspeakers

Using separate cables for treble and bass units in a Bi-Wiring
configuration reduces intermodulation effects and improves headroom
and clarity. To bi-wire, you will need to install two equal lengths of twin
core cable between the amplifier and each loudspeaker.

Unscrew each terminal a few turns and remove the metal straps.
Connect the cables between the amplifier and the loudspeakers as
indicated above and re-tighten all the terminals securely.

Note: Some amplifiers have two pairs of output terminals to facilitate bi­wiring but this is not essential. The advantages of bi-wiring are fully
retained if your amplifier has one pair of output terminals per channel

Bi-Amplifying (Bi-Amping)

By connecting each loudspeaker drive unit to its own dedicated amplifier
the advantages of Bi-Wiring can be extended. If you own two identical
stereo power amplifiers, your speakers may be Bi-Amped. For further
details please consult your dealer

.

The 9.4, 9.5 and 9.6 are designed to be floor standing. We suggest that
they are positioned at least 200 mm from the rear walls and 700 mm
from the side walls, facing slightly inwards. The 9.1, 9.2, and 9.3 should
ideally be stand or wall mounted though they may be placed on a rigid
shelf. The 9.0 can be stand or wall mounted. The bass extension will
improve if these smaller speakers are operated closer to the rear walls.

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 far 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 different
configurations and play a wide range of programmes before finalising
the position of your speakers.

Page 4

The subwoofer has to blend with the main speakers: 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 voice sounds coloured when the subwoofer is operating and less
coloured when in standby, you need to address the positioning first
before adjusting any controls

Loudspeaker Phasing

Make sure that all loudspeaker channels are connected in phase. Nothing
is more certain to defeat a Home Cinema or Stereo setup involving a
subwoofer than one(or more) channels being out of phase. In Stereo, if
there is a doubt about the way the loudspeakers are connected, check
their phasing by playing a mono source - the sound should appear from a
point midway between 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.

Setting the Phase of the Subwoofer

Phase at very low frequencies is not straightforward to detect. Initially
we suggest you temporarily set the low pass filter to ‘off’ and the phase
to 0º and play some bass heavy music in Stereo through the main
speakers and the subwoofer. From the listening position, switch the
phase between 0º and 180º. The setting which appears to give the greater
bass output is correct. Now follow the instructions below for setting the
low pass filter.

Home Cinema Systems

Low Pass Filter

If you are using a digital AV processor the initial setting should be ‘OFF’
as the processor will have its own bass management system. Most
digital AV Processors ask you to 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 loudspeakers are large floor
standing units, you should choose 'Small' for the Front channels, 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
any bass 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 may need to adjust the LPF
settings. The goal is to ensure the subwoofer blends seamlessly into the
sound stage. Setting the subwoofer to Standby should reduce the bass
extension, not change the bass level - as always personal taste plays an
important part.

Setting levels

Once the loudspeaker settings have been finalised, put the AV amplifier
into its “Test” mode (see instructions supplied with your processor.)
Adjust the levels until all channels are reproduced at equal loudness.
When adjusting the subwoofer output level avoid setting too high a level
or you will swamp the sound with bass which be tiring to listen to and
may limit the subwoofer’s ability to respond to large bass transients. Set
a sensible level going into the subwoofer from the processor. The
volume display should be around 50 at normal listening levels.

Page 13

LFE

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 from those 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,
lower the subwoofer volume level.

Note: If any channels are set to ‘Small’ the subwoofer must be on when
the system is playing otherwise there will be reduced bass , as well as no
LFE.

Stereo Reproduction

Low Pass Filter: The low pass filter should be set having regard to the
size and low frequency extension of the main speakers. The role of the
subwoofer is 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 45-55 Hz is a good place to start. With smaller
speakers this can be increased, up to 85Hz for very small bookshelf
units. As always the final value is determined by listening.

Low-level 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 produced a
series of ‘Equal Loudness Contours’. Occasionally we may wish to listen
to a normally loud piece of music at a low level but with retention of the
bass information. There may be a case for assigning a preset for low
level listening where the subwoofer volume is set somewhat higher and
the LPF is set a little lower - as always this is for individual judgement.

Testing the system By Ear

The simplest way to test the 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 setup needs to be refined further. By entering
different settings in different presets, you will be able readily to identify
the most favourable combination.

Using an SPL Meter

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 method you should definitely seek your
dealer’s advice beforehand.

ESSENTIAL INFORMATION FOR UK USERS

The power cord on your subwoofer may be supplied with a plug
incorporating a fuse, the value of which is indicated on the pin face of the
plug. Should the fuse need to be replaced, an ASTA or BSI approved
BS1362 fuse must be used of the same rating. If the plug is cut off it must
NOT be re-used. Dispose of any such plug safely. There is a danger of
electric shock if a cut-off plug is inserted into a mains socket.

The wires in the mains lead are coloured in accordance with the following
code: Green and Yellow - Earth: Blue - Neutral: Brown - Live.
As the colours of the wires in the mains lead may not correspond with the
markings identifying the terminals in the replacement mains plug,
proceed as follows:
The wire coloured Blue must be connected to the terminal marked with
the letter ‘N’ or coloured Black. The wire
coloured Brown must be connected to
the terminal marked with the letter ‘L’ or
coloured Red. The wire coloured Green
and Yellow must be connected to the

Do not operate your subwoofer closer than 450mm from the TV to avoid
distorting the colour picture. if this occurs, switch the TV set off. After 15
minutes switch on again: colour balance should now be restored.

To minimise hum and mains interference ensure that low level (line level)
signal cables are well screened. Avoid routing low-level signal cables
close to or parallel with mains power wiring.
