1. Introduction
Designed for a wide variety of sound reinforcement applications the Tannoy i6 AW (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 offers outstanding durability and
resistance to scuffs and knocks. Able to deliver consistent performance under a wide
range of adverse conditions the i6 AW is suited to applications indoors or out, whether
it be a theme bar or theme park. Available in dark grey or white the i6 AW will
effectively blend into most backgrounds.
Utilisation of the point source Dual Concentric loudspeaker allows the i6 AW 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).
The i6 AW comprises one 6.5 inch (165mm) Dual Concentric driver in which the low
frequency (LF) and high frequency (HF) sources are coincidentally aligned to a point
source, resulting in a smooth uniform frequency response over a wide area of
coverage. The sophisticated CAD designed waveguide combines 90 degree conical
dispersion and excellent acoustic impedance characteristics.
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.
2. Unpacking
Every Tannoy i6 AW 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 has two 4mm binding posts for connection to the amplifier, these are gold
plated in order to improve electrical conductivity and to prevent oxidisation. These
terminals are capable of accepting cables with a 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 length 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 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)
Determine the maximum power in watts needed at each speaker location. The i6 AW
transformer can be tapped at 30w, 15w, 7.5w, & 3.75w 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 7.5-watt transformer tap, it means that at full rated amplifier output the
speaker will receive the full 7.5 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 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.
Over equalisation can reduce system headroom, and introduce phase distortion
resulting in greater problems than cures. If equalisation is required then it should be
applied gently and smoothly. The i6AW loudspeaker is a point source, phase coherent
design and violent equalisation will be detrimental to the overall sound quality.

9. Hardware
The i6AW 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.
