AMPLIFIER CHOICE
Consult the enclosed product specification sheet as this clearly shows the acceptable power
range for amplifier matching to your speakers. The high peak power handling of Tannoy
loudspeakers permits responsible use with more powerful amplifiers - please read the
Warranty.
As with all loudspeaker systems, the power handling is a function of voice coil thermal
capacity. Care should be taken to avoid overdriving any amplifier, as this will cause output
overload resulting in 'clipping' or distortion within the output signal. This, if done for any
extended period, will cause damage to the speakers.
Generally an amplifier of higher power that is running hard, but free of distortion, will
do less damage to the loudspeaker than a lower power amplifier continually clipping.
Remember also that a high powered amplifier running at less than 90% of output power
generally sounds a great deal better than a lower powered example struggling to achieve
100%. An amplifier with insufficient drive capability will not allow the full performance of
the loudspeakers to be realised.
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 each
speaker. Remember, cable construction can affect the sound quality so be prepared to
experiment to find a cable that suits your ear and audio system.
TERMINAL PANEL DESIGNS
In the discrete models there is a robust bi-wiring terminal panel designed to take substantial
high quality loudspeaker cable. (See fig. 2)
An exclusive five way terminal panel has been designed for the Sensys Dual Concentric™
models to optimise performance further by take 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.

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)
FLOOR STANDING MODELS
Sensys floor-standing models perform best with carpet piercing spikes fitted. These are
supplied, along with lock nuts, and should be inserted into the threaded holes in the base
of the metal feet. Level the speaker and then tighten the lock nuts 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.
