TOA Electronics Speaker I6 AW ICT User Manual

i6 AW ICT & i6T AW ICT  
USER MANUAL  
 
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)  
Check the electrical continuity of  
the loudspeaker cables, and  
replace if necessary.  
Amplifier  
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  
Check and correct system  
grounding.  
Faulty electronic device in  
the signal chain  
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.
