1. Introduction
Designed for a wide variety of sound reinforcement applications the Tannoy
i6 AW ICT (All Weather) is an ultra compact loudspeaker system capable of
delivering high sound pressure levels with extremely low distortion, resulting in
outstanding clarity, definition and detail. A truly universal solution, the i6 AW ICT
offers outstanding durability and resistance to scuffs and knocks. Able to deliver
consistent performance under a wide range of adverse conditions the i6 AW ICT is
suited to applications indoors or out, whether it be a theme bar or theme park.
Available in black or white the i6 AW ICT will effectively blend into most backgrounds.
Utilisation of the point source ICT Drive unit allows the i6 AW ICT to be mounted on a
wall or ceiling in either horizontal or vertical orientations without affecting its
performance. A range of hardware options ensures simple and effective installation.
Also available with built in line transformer (i6T AW ICT).
This versatile design has addressed the two most common component failures
experienced in background music and sound reinforcement system installations,
namely the tweeter and the crossover. Due to the revolutionary design of the ICT™
drive unit, neither of these failures can occur, assuring you years of trouble free use.
ICT™ 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 dome 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™ dome is
at the heart of our 6.5” transducer which utilises a moulded plastic cone and nitryl
rubber surround to further enhance it’s durability and long term reliability.
For applications requiring extended low frequency enhancement, a range of Tannoy
sub-bass systems are available and can be used in conjunction with the i6 AW ICT.
2. Unpacking
Every Tannoy i6 AW ICT product is carefully inspected before packing. After
unpacking your loudspeakers, please inspect for any exterior physical damage, and
save the carton and any 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 i6AW ICT is fitted with two 4mm binding posts and a 4-pole Neutrik Speakon' for
connection to the amplifier. These are paralleled within the enclosure.
The two binding post terminals are capable of accepting cables with a conductor of
up to 6mm.
Red is Positive
Black is Negative
Speakon has the following advantages over EP and XLR type connectors: All
terminations are solderless; this makes life easier at the time of installation or when
field servicing is required. Contacts will accept 6 sq. mm wire with an outside
diameter of upto 15mm and a current rating of 30 Amps. The pins of the 2 Speakon
sockets identified input/output on the rear of the input panel are paralleled within the
enclosure. Tannoy have adopted the conventional wiring standard for the i6AW ICT
product:
Pin 1+ is Positive
Pin 1- is Negative
For a worldwide list of Neutrik distributors see http://www.neutrik.com/
Connectors should be wired with a minimum of 2.5 sq. mm (12 gauge) cable. This will
be perfectly 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 LF units is as follows: Connect two wires to
the +ve and -ve terminals of a PP3 battery. Apply the wire which 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 LF drive unit will move forward, indicating the wiring
is correct. All that remains now is to connect the +ve speaker lead to the +ve
terminal on the amplifier and the -ve lead to the -ve terminal on the amplifier. If
however the LF driver moves backwards, the input connections 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 & 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 impedance 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 manufacturers 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 being used with multiple cabinets; it is
therefore recommended that the same amplifiers be used throughout.
6. Power Selection (i6T AW ICT)
Determine the maximum power in watts needed at each speaker location. The i6 AW
ICT transformer can be tapped at 60w, 30w, 15w, with an extra 7.5W tapping for
70.7V line systems via the rotary switch located on the metal plate at rear of the
loudspeaker. 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 this amplifier. If for example, you select the 30-
watt transformer tap, it means that at full rated amplifier output the speaker will
receive the full 30 watts. If the amplifier gain is reduced each speaker will receive a
proportional amount of power, maintaining the overall system balance.
When calculating amplifier wattage requirements for a system, it is recommended
that a generous wattage 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 i6AW ICT loudspeaker 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 gently 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.
8. Dimensions
9. Hardware
The i6AW ICT can be wall or ceiling mounted using the MB6 (optional) bracket (fig 1.)
which is designed to offer the maximum flexibility in selecting the desired angles.
The MB6 is supplied with M8 bolts for fixing to the loudspeaker (fig1.& 2). After fixing
the bracket to the wall or ceiling remove the plastic plugs from the top and bottom of
the loudspeaker. Position the cabinet at the required angle as shown and tighten the
M8 Bolts to fix the loudspeaker in position.
The loudspeaker can be mounted either horizontally or vertically using the MB6
bracket (fig1.& 2.). This product has four M6 threaded holes in the rear of the cabinet
for other bracketry.

12. Troubleshooting Guide
Symptom
Possible Cause
Action
No Output From Speakers
Broken Speaker Cables(s)
Amplifier
Check the electrical continuity of
the loudspeaker cables, and
replace if necessary.
Check the gain controls on the
amplifier are turned up.
Be sure the amplifier is receiving
an input signal (check the
“signal” indicators on the amp).
Connect the loudspeaker cable
which has no output to another
amplifier channel you know is
working, make sure signal is fed
to the new amplifier channel. If
output is obtained from the
loudspeakers(s) then the
problem is with the amplifier
channel or input signal leads. If
this is not the case then the fault
may lie in the cabling or the
loudspeaker.
Intermittent Output
Poor Connection
Check the loudspeaker cabling
has a good electrical connection
with amplifier outputs and
loudspeaker inputs. A bad
connection can increase
resistance which will
substantially reduce the output,
or make “cracking” noises which
are unrelated to signal content
If using multi-strand loudspeaker
cable, be sure no strands of
cable are causing short circuits
between the positive and
negative terminals of the
amplifier outputs and/or
loudspeaker inputs.
Poor Low Frequency
Output
“Out of phase” connection
When two speakers are
connected “out of phase”, the low
frequencies will virtually be
cancelled out. Check the
connections at the
amplifier/speaker paying
attention to polarity. (see section
4).
Irregular sounds such as
buzzing and humming
emanating from the
loudspeaker
Poor system grounding
Faulty electronic device in
the signal chain
Check and correct system
grounding.
The speaker cannot generate
these sounds on its own. It is
most likely there is a fault with a
piece of electronic equipment in
the signal path.
