BEFORE INSTALLING THIS PRODUCT READ ALL THESE INSTRUCTIONS!
Read these instructions. Keep these instructions. Heed all warnings. Follow all instructions.
Before making any connections, switch all the units in your system o at the mains.
Set the volume control at minimum when you switch on your system or change sources and turn the level up
gradually.
DO NOT use your amplier at full volume.
Ensure that all loudspeakers in the system are correctly wired.
DO NOT subject your loudspeakers to excessive cold, heat, humidity or sunlight.
Loudspeakers should not be placed directly facing other hi- units, or share the same shelf or cabinet.
DO NOT place heavy objects on top of loudspeakers.
Some manufacturers forbid the placing of objects on top of their TV sets. Check your TV handbook before
installing the speaker directly on your TV set. Consult your TV dealer if you are in any doubt.
DO NOT connect speaker terminals to the mains supply.
DO NOT dismantle the loudspeaker. There are no user serviceable parts inside it and you will void the warranty.
Refer all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged in

Preparing The Crystal-4.3 and Crystal-4.4 Loudspeakers
Place a soft cloth on the oor to protect the speaker.
Invert the loudspeaker and place it on the cloth.
Thread a locking nut two-thirds of the way up the
spike. Thread each spike assembly into a spike mount.
Tighten nger tight so that spike is secure but not
locked in place.
Levelling The Loudspeaker
Invert the loudspeaker and place int carefully on the
oor. If the oor is not perfectly level you will nd that
one spike is o the ground. Starting with this spike,
unscrew it so that it touches the oor. Move the other
spikes in and out so until the speaker is level front and
back and sideways. Now tighten the nuts to lock the
spikes rmly in position.
Spike Seats: A set of spike seats is provided for
sensitive oors. Place a seat under each spike before
you level the speakers.
Caution: Spikes Are Sharp
Make sure that there are no wires or hidden obstacles
that could be damaged by the spikes in the
immediate operational area of the speakers. NEVER
drag a loudspeaker on its spikes. Always lift it. If the
item is heavy get assistance.

Positioning Stereo Loudspeakers
The Crystal-4.3 and Crystal-4.4 are oor standing. We
suggest they are positioned at least 200mm from
the rear walls and 700mm from the side walls, facing
slightly inwards. The Crystal-4.1 and Crystal-4.2 maybe
stand or wall mounted or placed on a rigid shelf.
The bass extension will improve if smaller speakers
are operated closer to the rear walls. If the
loudspeakers are placed too close to the walls the
bass will increase but maybe boomy and indistinct. If
the loudspeakers are placed away from the
walls, the inward angle maybe increased by up to
40%, but this may restrict the width of the optimum
listening position.
A rule of thumb is that the listener should be as far
from the loudspeakers as they are from each other.
The speakers should be ideally positioned so that the
treble units are roughly at ear level to a seated listener.
As personal taste plays a large role, experiment
with dierent congurations and play a wide range
of programmes before nalising the position of your
speakers.

Positioning Home Cinema Loudspeakers
5.1 Positioning
Place the front speakers as shown. Front loudspeakers
should be placed away from the walls for best results.
Angling the speakers inward slightly will improve
stereo images but too extreme an angle will impair
the movie sound.
All the speakers with the exception of the Crystal-4.
C must be placed at least 450mm from a CRT TV. Flat
panels are unaected.
The Crystal-4.C centre speaker can be placed above
or below the TV screen.
Subwoofer room positioning is not critical but we
recommend that it is placed in front of the listening
seat. Never operate the subwoofer within 450mm of a
conventional TV screen.
The surround speakers should be placed above and
behind the listening seat. They may be mounted on
the side walls or on the rear walls but always behind
a listener. Do not operate them within 450mm of a
conventional CRT TV.
If the distance between the side walls is too great, you
could use a second pair of stand mounted or oor
standing loudspeakers, as the surround loudspeakers
placed as shown in the drawing opposite.
7.1 Positioning
If you are using a 7.1 system, the back loudspeakers
must be at least 1 metre behind the listening seat.
Wall Monting Positions
If you arewall mounting the centre and eects
loudspeakers we recommend that they be mounted
as shown.
The Crystal-4.1 has integral speaker mounts. To wall
mount the Crystal-4.C we recommend that you
consult your dealer to advise you on a suitable wall
bracket.
Wall mounting the centre loudspeaker below the
screen is not recommended unless the screen is
mounted signicantly above eye level. Consult your
TV user guide for preferred placement options.

Wall Mounting The Crystal-4.1 Loudspeakers
The crossover terminal panel of the Crystal-4.1
loudspeaker is provided with an integral keyhole slot
for wall mounting. Wall mounting should be carried
out by licensed sound contractors or technicians
with appropriate qualications and experience. All
installations and wiring should comply with the
standards laid down by the competent authority
in the country and place of installation. Before you
attempt wall or ceiling mounting, ensure the surface
is stable and strong enough to support the weight of
the speaker and mounting hardware.
You will need 1 No.8 screw and matching wall plug
to attach each loudspeaker to the wall. These are
the responsibility of the installer who should supply
suitable xings for this purpose.
Drill one 6mm hole in the wall at a suitable height o
the oor. Fix a suitable No 8 round head screw rmly
into each hole using appropriate wall plugs. Leave
a stub of 7mm protruding from the wall. Align the
keyhole slot in the crossover panel over the screw
head and carefully lower the unit onto the screw.
Remove the loudspeakers from the wall ready for
connection. After connection they can be re-installed
on the wall.

Connecting Your Loudspeakers
USER INSTRUCTIONS: Crystal 4 Series USER INSTRUCTIONS: Crystal 4 Series
40mm

Terminal Panels
All the loudspeakers are connected to the amplier
via a twin terminal connecting panel. The positive
terminal is located at the right of the panel and is
coded red, the negative terminal is coded black.
Cable Preperation:
Prepare a suitable length of loudspeaker cable for
each unit. Split the twin cores to a depth of about
40mm. Carefully strip the insulation from each
end, leaving about 8mm of bare wire. If the cable is
stranded, lightly twist together any loose strands.
Threading Cable
Unscrew a 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.
Amplier – Speaker Connections:
Audio cable is polarised, with two cores of dierent colours, or often a coloured tracer or identication rib. We
suggest that you connect the coloured / striped wire to the red, positive terminals of your AV amplier. This will
ensure that all the loudspeakers are connected the correct way round and avoid set-up problems.
Connect each loudspeaker to the correct channel of your amplier or AV processor taking care to connect
the red (+) positive terminal of the speaker to the red, positive (+) terminal of the speaker output terminal of the
amplier and similarly with the black, negative (-) terminal. Use the connection diagrams on the next page to
help you.

Setting Up A Stereo System
Ensure that the listening seat is central to the loudspeakers.
Play some music with which you are familiar. Adjust the speakers for the optimum performance. You will nd that
a few degrees more or less ‘toe in’ can eect the sound dramatically.
The sound should be well balanced with a rm bass. If the sound lacks denition or the bass is indistinct, the
Setting Up An AV System
Please read the relevant sections of your AV amplier manual and familiarise yourself with the various
issues. If you are unsure, consult your dealer for help.
Most digital AV processors require you to specify the size of speakers in all operational channels. These are
usually ‘Large’ or ‘Small’. Set all the bookshelf speakers to ‘Small’. This will direct all the bass in the system to the
subwoofer for clean, deep and louder bass. The oorstanding loudspeakers should be set to ‘Large’. It is normal
for a centre and eects speakers to be set to ‘Small’. Set the ‘Subwoofer’ option n the processor to ‘On’. If there is
no subwoofer in the system set all the speakers to ‘Large’ and set the subwoofer to ‘O’.
When the loudspeaker settings are nalised, put the AV amplier into its ‘Test’ mode (see your processor
instruction) and adjust the levels until all channels are equally loud.
