CABLE CHOICE
Always use the best quality of cable available within your budget. High quality audio signals passing from the
amplifier to the loudspeaker are unusual in their demands on the cable. Wide dynamic range and frequency
bandwidth information has to coexist with the ability to transmit peak currents of at least 10amps, without
incurring any loss or signal impairment. This explains why the sound quality of the information reproduced by the
loudspeakers is so dependant on the physical properties of the cables connecting them to the amplifier.
We would recommend that you always keep the cable runs the same length for left and right speakers.
Remember, cable construction can affect the sound quality so be prepared to experiment to find a cable that suits
your ear and audio system.
UNPACKING
To unpack the loudspeakers from their boxes remove tape from the top then fold the flaps right back before
inverting the carton and contents. Lift the carton clear of the contents then remove all inner packaging.
It is strongly recommended that you store all the packaging to allow protected transportation in future. (See Fig. 1)
TERMINAL PANEL
An exclusive five-way terminal panel has been designed for the Precision range to optimise performance further
by taking advantage of the driver earthing facility. Use a shielded or screened loudspeaker cable; connecting
the screening termination to the earth or ‘ground’ (green) terminal on the loudspeaker and to the ground or earth
connection on the amplifier. Alternatively if you are not using a screened loudspeaker cable but wish to utilise the
earthing facility, run a single cable between the earth or ‘ground’ (green) terminal on the loudspeaker to the earth
(ground) connection on the amplifier.
FLOOR STANDING MODELS
These models are designed to be mass loaded, to lower the centre of gravity and improve stability, resulting in
improved sound quality. To do so, remove the 4 screws securing the plinth to the bottom of the speaker , then
remove the 4 further screws as shown (See Fig. 2). The main loading volume can be filled with sand (which must
be dry), or propriety materials available for such purposes.
Precision floor-standing models perform best with carpet piercing spikes fitted. These are supplied, along with
locking wheels, and should be inserted into the threaded holes in the base of the cabinet. Level the speaker, using
the hex key provided and then tighten the locking wheels firmly but without using undue force. Spike locating cups
are provided in the accessory pack and these may be used to protect sensitive floor surfaces. (See Fig. 3)
Warning:
Ensure that the spikes are levelled and that the lock nuts are tightened firmly. The spikes should be
pushed through the carpet to locate into the flooring surface by applying pressure to the top of the
cabinet. If using on a sensitive floor surface place the protective cups under the levelled spikes. Failure to
do so could render the speaker unsteady and result in damage or injury should it be knocked over.
STAND MOUNTING MODELS
Stand mounting or bookshelf speakers should be located securely on stands or a shelf in an appropriate position
to place the Dual Concentric driver high frequency unit roughly at ear height when seated in the chosen listening
position. Positioning recommendations for stand-mounted speakers can be found under the section entitled
Positioning and fine-tuning.
