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.

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
