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.
