Your Krix speakers are designed to reproduce the highest quality sound. To get the best
performance from your speakers please read this owner’s manual carefully, there are many
factors that infl uence the performance of your speakers. If you have any diffi culties please
speak with one of our friendly authorised Krix dealers.
Congratulations on choosing Krix

positioning
Achieving the best position for your speakers
may need some testing. As a guide there
should be equal distances between the front
left and right speakers and the listener (see
fi gure 1). Position centre channel speakers,
Microcentrix, KDX Centre and Centrix, directly
above or below your television, and ideally
aimed at head height when seated. Rear
speakers (for home theatre) should be
placed to each side and behind the listener.
Magnetically sensitive equipment (televisions,
computer screens, CD’s, video tapes etc)
should be at least 50cm (1.64 feet) clear of
the speakers to avoid interference. Krix models
Microcentrix, KDX Centre, KDX Main, Centrix
and Brix are magnetically shielded and will
not interfere with this equipment.
Some tips for optimum sound performance:
1. Sound quality is decreased with lots
of objects immediately surrounding
the speakers.
2. Placing loudspeakers close to a wall or
in corners can artifi cially boost the bass.
Inserting vent plugs (if your model permits)
can reduce the bass response to a more
acceptable level. See ‘speaker accessories’
for more details.
3. Poor quality cables can result in loss of
bass strength and clarity, particularly over
long distances.
4. Rugs, wall coverings, curtains and soft
furniture can improve sound in rooms with
lots of bare surfaces like fl oorboards.
amplifi er and speaker power ratings
Krix speakers come with a maximum power
rating. The rating gives you a guide to match
the appropriate amplifi er with your speakers.
When the input level to the amplifi er is very
high, as with CD/DVD players, maximum output
power is reached on the amplifi er before the
volume dial is at full. When using a CD/DVD
player, maximum output power can be at
approximately 12 o’clock on the volume dial.
Amplifi ers with the volume level shown on
a digital display make it hard to judge when
maximum power is reached. As a guide, we
suggest that you do not exceed zero on the
digital display.
Turning the volume dial past the amplifi er’s
maximum output power will create distortion
(clipping) (see fi gure 2). Inputting a distorted
signal into your speakers over a prolonged
period will damage them. You can damage
a 200 Watt speaker with a 50 Watt/channel
amplifi er delivering a distorted signal just as
easily as you can damage a 50 Watt speaker
with a 200 Watt/channel amplifi er delivering
too much power. Running an amplifi er at
very high volume over a prolonged period can
even damage a compatible speaker/amplifi er
combination. For more information contact
your authorised Krix dealer or visit krix.com
connecting
To ensure optimum performance it is important
that your speaker system is connected properly:
1. Turn off all electronic equipment and
disconnect from the power point.
2. Follow the connection instructions supplied
with your amplifi er, CD/DVD, tape deck,
video player etc.
3. Connect the speaker cables between the
amplifi er and the speakers with cables that
are neatly stripped at the ends. Loose frayed
wires could cause a short circuit. Unscrew
the binding posts on both the amplifi er and
speaker and insert the wire through the hole
in the shaft. Alternatively you can use Spade
lugs or Banana Plugs (see fi gure 3).
4. Match the cables between the amplifi er and
the speakers positive (+) with positive (+)
and negative (-) with negative (-). The left
speaker must connect to the left channel
and the right speaker to the right channel
of the amplifi er (see fi gure 4).
5. Bi-Wiring is available for Krix models Lyrix
Gold, Symphonix and Neuphonix. Run two
sets of speaker cables from your amplifi er
to each speaker. At the amplifi er twist the
two ‘+’ wires together and the two ‘-’ wires
together and insert into the respective ‘+’
and ‘-’ terminals. At the speaker remove
the gold plated joining bars completely
(see fi gure 5), then from one of the cables
insert the ‘+’ and ‘-‘ wires into the top
set of terminal posts and the other set
into the bottom terminal posts. Krix model
Esoterix may be tri-wired by following
the same procedure with a third set of
speaker cables.
tone controls
Your Krix speakers do not require adjustment
to the treble or bass. If you wish, you can
adjust the tone controls for reasons of personal
taste or room acoustics, however this may
damage your speakers particularly when the
amplifi er is operating at maximum output (see
fi gure 6). For more information please contact
your authorised Krix dealer or visit krix.com.
speaker accessories
Vent plugs - for Krix models: Apex 3, Lyrix
Gold, Symphonix and Esoterix. Vent plugs
are provided to fi ne tune the bass response
below 50Hz. Vent plugs restrict the fl ow of
air, reducing bass energy. They are supplied
to allow the user to adjust the bass response
to suit personal tastes when speakers are
placed too close to walls and corners. Please
note in most circumstances vent plugs are
not required. The vent plug is placed in the
specifi c hole in the back of the speaker.
Floor spikes - for Krix models: Lyrix Gold,
Symphonix, Neuphonix and Esoterix. Floor
spikes are used to lift the speaker from the
fl oor, improving overall sound quality and
providing a tighter bass response, particularly
on wooden fl oors. Floor spikes need to be
screwed into the spike barrel in the speaker
plinth with the lock nut tightened down
over the spike. To protect uncarpeted fl oors,
place small metal discs or coins underneath
the spikes.
caring for your krix speakers
To clean your speaker cabinet gently wipe
with a damp cloth. Do not rub hard on the
cabinet in one spot, you will leave a polished
spot. The cloth grille, bass driver(s) and tweeter
can be dusted by using a soft bristled brush
to gently remove excess dust. To remove the
cloth grille fi rmly grip the edges and gently
pull away to reveal the front baffl e and drivers.
To reinstall the grille, line up grille clips with
small holes in the front baffl e and gently push
until locked in place. Wherever possible, do
not touch the tweeters, they are fragile and
easily damaged.
