WARRANTY

This equipment has been produced and tested with care and precision. All Tannoy
speaker systems are built to give first class service and carry a 5-year warranty.
Active subwoofers carry a 1-year warranty.

2

If the equipment proves to be defective within this period for any reason other than
accident, misuse, unauthorised modification or fair wear and tear, Tannoy will repair
any such defect or, at our option, replace it without charge for parts, labour or return
carriage. This warranty is given in addition to the customer's statutory rights.

If you suspect a problem with your loudspeakers please contact your local Tannoy
dealer who will be able to advise on appropriate action.

INTRODUCTION

Thank you for selecting Tannoy loudspeakers developed in the UK by our dedicated team of design engineers. They are the
choice of discriminating music lovers the world over. Musical excellence is designed into our loudspeakers from the start.
Careful selection of the very best components combined with strict quality control procedures in the production process
ensures this level of excellence is maintained.

To gain maximum performance from your loudspeakers, please take time to read this owner's manual in full before installation.
Once you have set up your new loudspeakers please complete and return the registration document - this does not limit your
legal rights.

Loudspeakers are electromechanical devices that 'run-in' through use; performance will therefore improve after an initial
period of 24hrs use. Once they have been further run-in over a longer period, there will be clear enhancement of the stereo
imaging, mid-band quality and bass performance characteristics.

We are confident that you will continue to enjoy your new Tannoy Dimension loudspeakers for many years to come.

WIDEBAND TECHNOLOGY

A Tannoy SuperTweeter is incorporated into the design of all Dimension models, not only to resolve fine detail of high
frequency information but also to effectively enhance the listening experience throughout the whole frequency range. The
Dimension SuperTweeter creates an increased immediacy, airiness and impact making music sound more natural and true
to life.

Music contains transient information and rich harmonics beyond the range of human hearing for pure tones. Even bass notes
have leading edge transients reaching 30kHz. Operating between the roll-off point of the Dual Concentric™ high frequency
unit and 54kHz, the Dimension SuperTweeter will accurately reproduce the leading edge of individual notes allowing the
listener to experience the entire bandwidth information of instruments.

In addition, by extending the frequency response by two octaves corrects time and phase response within the bandwidth of
normal human hearing. Taking these acoustical phase anomalies beyond the range of human hearing adds realism to the
soundstage by improving imaging and placement of instruments.

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

(See fig. 1)

In order to take advantage of the driver earthing feature within the Dimension range and to optimise performance further,
use a shielded or screened loudspeaker cable. The screening termination should be connected 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

WARNING: THESE LOUDSPEAKERS ARE HEAVY - SEEK ASSISTANCE WHEN LIFTING.

To remove the loudspeakers from the packaging please follow these instructions carefully:
Lay the carton on the floor noting that the text (OPEN THIS END) on both ends of the box are visible and the arrows on the

carton ends point towards the floor - in this position the speaker in the carton will be positioned on its back. Remove the
packing tape from both ends of the carton and fold the carton flaps right back. The spike kit (containing rear spikes, nuts,
washers, cone tips and floor protection cups) is immediately visible. These accessories are essential for optimum performance
and for providing a rigid and stable footing for the speaker. The secure interface between the cabinet and the floor brings
about an improvement in clarity, bass 'speed' and definition.

To facilitate easier removal of the Dimension speakers from their packaging, the carton side has been fitted with plastic
locking devices, which allow the carton to be fully opened along its length, and then folded back. To remove each of the
plastic locks, insert two fingers into the device and pinch the two flat ribs together - this will unlock the ribs and allow the
whole locking mechanism to be pulled free from the box. Once all the locking devices have been removed, fold back the
carton to reveal the contents. Carefully remove the packing material from the bottom of the loudspeaker so that this end of
the speaker can be carefully lowered onto the floor. Follow the rest of the instructions below regarding the fitting of cones
and spikes BEFORE tilting the speaker into an upright position.

It is strongly recommended that you store all the packaging to allow protected transportation in future.

WARNING: IT IS IMPERATIVE THAT THE SPIKES AND CONE TIPS ARE FITTED BEFORE THE SPEAKER IS PLACED
IN AN UPRIGHT POSITION. FAILURE TO DO SO MAY CAUSE THE SPEAKER (ESPECIALLY TD 12) TO TIP OVER
WITH THE RISK OF DAMAGE OR INJURY.

The spikes, along with washers and lock nuts, should be fitted loosely into the threaded holes in the base at the rear of the
cabinet. The cone tips should then be threaded into the ends of the polished alloy cones at the front of the speaker. Level
the rear spikes to the front cones by eye then hand tighten the lock nuts. Spike locating cups are provided and these may
be used to protect sensitive floor surfaces.

The loudspeaker can now be carefully lifted into an upright position and the packing piece removed from the top panel.

3. Refer to the paragraph headed 'Positioning' for speaker placement advice.

4. The alloy side strips of the speaker are protected with a plastic film; it is recommended that this be left on for protection
and should not be removed until the speaker is fully installed.
