1. Introduction

The Tannoy i5 AW has been designed to be both sonically and cosmetically pleasing
for all applications ranging from background music in a restaurant to live keyboard
monitoring on stage.

ICT

TM

or Inductive Coupling Technology utilises a wireless electromagnetic tweeter
that does not require a crossover and cannot be burned out from heavy or abusive
use. The 1" aluminium high frequency dom e has a deep drawn skirt which sits on the
inside of the low frequency voice coil in the same magnetic gap. The skirt is like a
single shorted turn, which is induced with high frequency information generated by
the low frequency voice coil, which is fed a full bandwidth signal. The ICT

TM

dome is
at the heart of our i5 AW transducer which utilises a moulded plastic cone and nitryl
rubber surround to further enhance its' durability and long term reliability.

The ICT

TM

driver is housed in a plastic enclosure that has been optimally tuned to

achieve maximum bass response and tonal balance.

For applications requiring extended low frequency enhancement, a range of Tannoy
sub-bass systems are available and can be used in conjunction with the i5 AW.

The i5 AW is also available as a Transformer version (i5T AW), for use from 70.7V or
100V line systems

2. Unpacking

Every Tannoy i5 AW is carefully inspected before packing. After unpacking, please
inspect for any exterior physical damage, and save the carton and an y relevant
packaging materials in case the loudspeaker again requires packing and shipping. In
the event that damage has been sustained in transit notify your dealer immediately.

3. Connectors/Cabling

The i5 AW has two spring-loaded terminals for connec tion to the amplifier. These
terminals are capable of accepting cables with conductor diameter of up to 6mm.

Red is Positive
Black is Negative

Cable choice consists mainly of selecting the correct cross -sectional area in relation
to the cable lengt h and the load impedance. A small cross - sectional area would
increase the cables' series resistance, inducing power loss and response variations
(damping factor).

Connectors should be wired with a minimum of 2.5 mm

2

(12 gauge) cable. This will
be perfect ly satisfactory under normal conditions. In the case of very long cable runs
the wire size should exceed this, refer to the following table for guidance: -

4. Polarity Checking

It is most important to check the polarity of the wiring. A simple method of doing this
without a pulse based polarity checker for the drive unit is as follows: Connect two
wires to the +

ve

and -veterminals of a PP3 battery. Apply the wire that is connected to

the +

ve

terminal of the battery to the speaker cable leg which you believe to be

connected to the red speaker terminal and likewise the -

ve

leg of the battery to the

black speaker terminal.

If you have wired it correctly the drive unit will move forward, indicating the wiring is
correct. All that remains now is to connect the +

ve

speaker lead to the +veterminal on

the amplifier and the -

ve

lead to the -veterminal on the amplifier. If however the driver

moves backwards, the input con nections need to be inverted.

If problems are encountered, inspect the cable wiring in the first instance. It should
also be noted that different amplifier manufacturers utilise different pin configurations
and polarity conventions, if you are using amplifiers from more than one
manufacturer, check the polarity at the amplifiers as well as the loudspeakers.

5. Amplification and Power Handling

As with all professional loudspeaker systems, the power handling is a function of
voice coil thermal capacity. Care should be taken to avoid running the amplifier into
clip (clipping is the end result of overdriving any amplifier). Damage to the
loudspeaker will be sustained if the amplifier is driven into clip for any extended
period of time. Headroom of at least 3dB should be allowed. When evaluating an
amplifier, it is important to take into account its behaviour under low impedance load
conditions. A loudspeaker system is highly reactive and with transient signals it can
require more current than the nominal impe dance would indicate.

Generally a higher power amplifier running free of distortion will do less damage to
the loudspeaker than a lower power amplifier continually clipping. It is also worth
remembering that a high powered amplifier running at less than 90% of output power
generally sounds a lot better than a lower power amplifier running at 100%. An
amplifier with insufficient drive capability will not allow the full performance of the
loudspeaker to be realised.

It is important when using different manu facturers amplifiers in a single installation
that the have very closely matched gains, the variation should be less than +/ - 0.5dB.
This precaution is important to the overall system balance when only a single
compressor/limiter or active crossover is bei ng used with multiple cabinets; it is
therefore recommended that the same amplifiers be used throughout.

6. Power Selection (i5T AW)

Determine the maximum power in watts needed at each speaker location. The i5T
AW transformer can be tapped at 30W, 15W, 7.5W and 3.5W via the rotary switch
located at the rear of the loudspeaker, at either 70 or 100-Volt lines. When the
relevant tappings have been selected add the individual wattages required at all
speakers and select an amplifier with a rating equal to or exceeding the total wattage
required. All of the transformer primaries should be connected in parallel to the output
of the amplifier. If for example, you select the 7.5W transformer tap, it means that
at full rated amplifier output the speaker will receive the full 7.5W. If the amplifier
gain is reduced each speaker will receive a proportional amount of power,
maintaining overall system balance.

When calculating amplifier wattage requirements for a system, it is recommended
that a generous wattag e safety margin (3dB of headroom) be left so that the system
does not have to operate continuously at its full rated output.

7. Equalisation

The i5 AW is designed to need no equalisation or correction to overcome system
limitations. As a result, it will only need equalisation to compensate for difficult
acoustic environments.

Excess equalisation can reduce system headroom, and introduce phase distortion
resulting in greater problems than it cures. If equalisation is required then it should be
applied ge ntly and smoothly. Violent equalisation will be detrimental to the overall
sound quality. If the loudspeakers were being used consistently at high levels it would
be beneficial to introduce a high-pass filter at 50Hz to protect the loudspeaker from
any unnecessary subsonic frequencies.

NOTE: The installation of this product must be
carried out in conformity with local building
standards. If necessary consult your local safety
standards officer before installing any product.
Alternatively, check any laws or bylaws. Tannoy
will not be held responsible for any damages
caused by the improper installation of any

9. Hardware

The i5 AW can be wall or ceiling mounted using the MB5Y bracket (Figure 1) or the
MB5B (Figure 3). Both are designed to offer maximum flexibility in selecting the
desired angles. Methods of mounting have been demonstrated in figures 2 & 3.

For this product to conform to weatherproof specification IP33CS in EN60529 it
should be mounted facing downwards at an angle greater than 35° from the vertical
