AMPLIFIER CHOICE

Consult the product specification 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 10 amps, without
incurring any loss or signal impairment. This explains why the sound quality of the information reproduced by the
loudspeakers is so dependent on the physical properties of the cables connecting them to the amplifier.
We would recommend that you always keep the cable runs as short as possible and the same length for each
speaker. Remember that 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)

FLOOR STANDING MODELS

Revolution XT 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 cabinet. 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.
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.
The Revolution XT Mini may also be wall mounted with a suitable bracket, using two inserts on the rear of the
loudspeaker, with standard 60mm spacing. The thread in the inserts is M5. It is the responsibility of the customer
to ensure the chosen bracket is used within its load rating, and the bracket is securely mounted to the wall with
suitable hardware.
