Positioning
Locate the loudspeakers so that the favourite listening position is approximately 15° from the axes of the cabinets. The axes of both cabinets
should intersect at a point slightly in front of the listening position. Remember that the proximity of the loudspeakers to walls and corners
will aff ect the sound. Some experimentation will probably be needed to fi ne-tune the stereo image depth and low frequency sound quality.
Close to wall positions and room corners have the eff ect of increasing very low frequency sound energy. Refl ective adjacent walls may upset the
stereo image by causing unwanted refl ections.
In order to experience the best acoustic performance and fully realise their exceptional stereo image depth capabilities, the loudspeakers
should ideally be used at least 1m from any sidewall or refl ective surface and at least 0.5 m away from a rear wall.
Inserts are provided in the base of the speakers for down spikes that give maximum stability. The spikes provided should be screwed into the
base of the loudspeakers. When the loudspeaker is installed in its upright position, the spikes should pass between the weave of your carpet to
contact the fl oor beneath.
Adjust the spikes for maximum stability, then tighten the lock nuts fi rmly, but without using undue force.
For polished wooden fl oors and other delicate surfaces, metal cups are provided to place under the spikes.

Connection
Consult the product specifi cation section within this manual as this clearly shows the acceptable power range for amplifi er matching to your
speakers. As with all loudspeaker systems, the power handling is a function of voice coil thermal capacity. Care should be taken to avoid
overdriving any amplifi er, as this will cause output overload resulting in 'clipping' or distortion within the output signal. This can cause damage
to the speakers if done for any extended period. Generally an amplifi er of higher power that is running hard, but free of distortion, will pose less
risk of damage to the loudspeaker than a lower power amplifi er continually clipping. Remember also that a high powered amplifi er running at
less than 90% of output power generally sounds a great deal better than a lower powered example struggling to achieve 100%.
Always use the best quality of cable available within your budget. High quality audio signals passing from the amplifi er to the loudspeaker are
unusual in their demands on the cable. Wide dynamic range and wide bandwidth information has to coexist with the ability to transmit peak
currents of at least 10 amps, without incurring any loss or signal impairment. We would recommend that you always keep the cable runs the
same length for each speaker. Remember that cable construction can aff ect the sound quality so be prepared to experiment to fi nd a cable that
suits your ear and audio system.

LINKS IN PLACE
First link the HF+ terminal to the LF+ terminal and HF- terminal to the LF- terminal, using the links provided in the accessories pack.
The positive (plus) terminal on the amplifi er left channel (marked + or coloured red) must be connected to the positive HF terminal on the left
speaker. The left speaker is the one on the left as you look at the stereo pair from your listening position. The negative (minus) terminal on the
amplifi er left channel (marked - or coloured black) must be connected to the negative HF terminal on the left speaker.
Repeat this connection process for the right speaker. Remember that the positive (+ or red) on the amplifi er must be connected to the positive
(+ or red) on the speaker and the negative (- or black) to negative. Select a signal source, such as a CD player, switch on the amplifi er and slowly
turn up the volume control to check that both loudspeakers are reproducing bass and treble information.
Earth Connection:
To optimise performance further, use a shielded or screened loudspeaker cable in order to reduce unwanted radio frequency interference.
The screening termination should be connected to the earth or ground (white) terminal on the loudspeaker and to the ground or earth
connection on the amplifi er. Alternatively, if you are not using a screened loudspeaker cable but wish to utilise the earthing facility, run a single
cable between the loudspeaker and amplifi er earth terminals.
