1. Introduction

Thank you for purchasing Tannoy i8 AW.

Designed for a wide variety of sound reinforcement applications the Tannoy i8 AW (All
Weather) is an ultra compact loudspeaker system capa ble of delivering high sound
pressure levels with extremely low distortion, resulting in outstanding clarity, definition
and detail.

A truly universal solution, the i8 AW offers outstanding durability and resistance to
scuffs and knocks. Able to deliver co nsistent performance under a wide range of
adverse conditions the i8 AW is suited to applications indoors or out, whether it be a
theme bar or theme park. Available in charcoal grey or white the i8 AW will effectively
blend into most backgrounds.

Utilisation of the point source Dual Concentric loudspeaker allows the i8 AW to be
mounted on a wall or ceiling in either horizontal or vertical orientations as well as pole
mounted, without affecting its performance. A range of hardware options ensures
simple and effective installation. Also available with built in line transformer (i8T AW).

The i8 AW comprises one 8 inch (200mm) Dual Concentric driver where the low
frequency (LF) and high frequency (HF) sources are coincidentally aligned to a point
source, resulti ng in a smooth uniform frequency response over a wide area of
coverage. The sophisticated CAD designed waveguide combines 60° 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 i8 AW.

2. Unpacking

Every Tannoy i8 AW product is carefully tested and inspected before packing. After
unpacking, please inspect your i8 AW for any damage sustained during transit. In the
unlikely event of any damage, would you please notify your dealer immediately and
retain your shipping carton, as you dealer may ask the faulty unit to be returned for
inspection.

3. Connectors/Cabling

The i8 AW is fitted with two 4mm binding posts and a 4-pole SpeakonTMfor
connection to the amplifier. These are paralleled within the enclosure.

The two binding post terminals are capable of accepting cables with a conductor
diameter of up to 6mm.

Red is Positive
Black is Negative

For the 4-pole SpeakonTMhas the following advantages over EP and XLR type
connectors: All terminations are solderless, which makes installation and field servicing
easier. Contacts will accept 6sq.mm wire with an outside diameter of up to 15mm and
a current rating of 30 Amps. Tannoy have adopted the following wiring standard for the
SpeakonTMsocket:

Pin 1+ is Positive
Pin 1 - is Negative

Should you encounter any problems obtaining Speakon connectors, please contact
Neutrik or its distributors dir ectly on the following numbers: -

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 variati ons (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 fo r 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 likew ise 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 should 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, so if you are using amplifiers from more than one manufacturer,
check the polarity at the amplifiers as well as the loudspeakers.
