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.

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.
