1.INTRODUCTION

1.1.General Amate Electroacústica, s.l. would like to thank you for your confidence in our new

MA and MAW Series, specially designed for Line Array configurations.

The accumulated experience of more than 30 years in the design of acoustic cabinets and amplifiers, together with the application of the most advanced technology and transducers, have allowed this series to become the optimal and ideal solution for a wide range of situations, specially those which require high levels of sound pressure and a control of vertical coverage. Stadiums, theatres, big events, etc... will become the perfect places for its use.

We suggest you carefully read the following instructions in order to obtain the best results in performance.

1.2.What is a line array?

The trend in sound reinforcement has been to increase both the sound pressure level (SPL) and the size of the audience to be covered. This leads to an increase in the number of cabinets and, as a result of this, an increase in the total size and weight.

A line array is a group of independent sound sources which are vertically stacked in order to transform the spherical wavefronts generated by individual sources into a single flat wavefront.

Fig.1. Wavefield interference for different wavefronts.

To carry out effectively arraying individual sound sources the system must follow the acoustic coupling conditions based on the wavelength, the shape of each source, the surface area of each transducer and the relative source separation.

An assembly of individual sound sources arrayed with regular separation between the sources on a plane or curved continuous surface is equivalent to a single sound source having the same dimensions as the total assembly if the following conditions are fulfilled:

Page 4

Amate Electroacústica,s.l.

MA206/MAW115.Version 1.3 Nov 08

1) The step of source separation, defined as the distance between the acoustic centres of the individual sources, is smaller than half the wavelength over the bandwidth of operation.

d<= λ/2

It is easy to fulfil this first condition for the low and mid frequencies. For example, two 7" loudspeakers that are separated by 17 cm will reproduce a cylindrical wave up to 1015 Hz.

This condition is difficult to be fulfilled for the high frequencies, as their wavelengths are too small to make the adjacent acoustic centres any smaller than λ/2. Here comes the second "arrayability" criterion.

2) The wavefronts generated by the individual sources are planar and the combined surface area of the sources fills at least 80% of the total target surface area:

H1·W + H2·W+.....+Hn·W >=0.8·H·W

This is achieved by using waveguides, which are coupled to the compression drivers output. We achieve flat wavefronts with a constant phase. By vertically assembling these waveguides we fulfil the second criterion of line array construction.

Fig.2. Second criterion of "arrayability"

3) The deviation from a flat wavefront must be less than λ/4 at the highest operating frequency (this corresponds to less than 5 mm curvature at 16kHz).

This third condition can be explained through our property waveguide. Thanks to some complex mathematical calculations we have obtained an aluminium component which is able to adapt the circular section of the compression driver to a rectangular section, getting on-phase waves at the end of the guide. This flat wavefront is ideal for vertical configurations.

Amate Electroacústica,s.l.

MA206/MAW115.Version 1.3 Nov 08

Sound engineers use line arrays to obtain narrow directivities on the vertical plane. For configurations with many cabinets (big height) and at high frequencies it is not unusual to achieve narrow angles- in some cases they may be grade fractions. This can be useful in venues where both a high sound pressure level and long throw are required; nevertheless, this means less coverage of the audience area.

It is sometimes useful to achieve an asymmetrical coverage pattern on the vertical plane, which can be obtained by aiming some of the cabinets through their hinging points. We are now ready to define the last two criteria of "arrayability".

4) For curved arrays, the tilt angles should vary in inverse proportion to the listener distance (this is geometrically equivalent to shaping variable curvature arrays to provide equal spacing of individual element impact zones).

5) There are limits given the vertical size of each cabinet and their relative tilt angles. In our case the maximum angle between cabinets is 8º .

Fig.4. Tilt angle between cabinets (8º maximum)

1.3.Fresnel Region (Near Field) and Fraunhofer Region (Far Field)

If our system is able to fulfil the previous conditions it will produce cylindrical waves to a maximum frequency. The wave will be flat up to a certain distance where it will start to become spherical (depending on the frequency and the size of the array).

The limit distance between the zone of cylindrical waves (Fresnel) and spherical waves (Fraunhofer) can be calculated through the following formula

Amate Electroacústica,s.l.

MA206/MAW115.Version 1.3 Nov 08

In the near field region (Fresnel), the wavefront is cylindrical and waves only expand

on the horizontal plane (90º in MA-206). The height of the wavefront is, in this case,

the total height of the array.

In the far field region (Fraunhofer), the wavefront is spherical and expands both on the horizontal and vertical planes. The horizontal coverage is 90º and the vertical coverage is defined by the frequency and the height of the array.

Calculation

A 12-cabinet array has a near field extending to 15 metres at 2kHz. Beyond this distance the wavefront will be spherical.

In the first zone (Fresnel), sound pressure loss is of 3 dB per doubling of distance, whereas in the second zone (Fraunhofer) the loss is 6 dB. In long throw and high SPL configurations it is very important to produce cylindrical waves.

2. MA-206 SYSTEM DESCRIPTION Amate Electroacústica offers the basic set of the MA-206 System which includes:

3 units of the MA-206/P 1 unit of the MA-206/D

This last model is the main unit and includes all the necessary electronics to feed

three MA-206/P units.

Both models include the same electroacoustic components. They are 2-way units that use two 6.5" for the low-mid frequencies and one 1" compression drivers (44mm voice coil) coupled to property waveguides for the high frequencies. We also

introduce a low frequency reinforcement cabinet called MAW-115 in its active with DSP version (MAW-115/D).

2.1.Front design

The MA-206 shape is "trapezoidal-flat". The "baffles" are flat-shaped and the cabinet

has a trap angle of 2 x 5º.

Amate Electroacústica,s.l.

MA206/MAW115.Version 1.3 Nov 08

2.2. 6.5" Neodymium Woofers

The low-mid way includes two 6.5" Neodymium woofers, with 1.5" aluminium voice coil

2.3. 1" Compression drivers with waveguide

The high frequency way includes one 1" compression drivers coupled to planar waveguides. Thanks to their Pure Titanium 44mm diaphragm we achieve an extremely good and clear sound, better than any other option.

The accurate design of our waveguide transforms the spherical waves produced by the driver into planar waves, while transversal stationary waves are also avoided within the audio field (up to 20kHz).

2.4.Finish

In its continuous research into offering the best product at all levels, the MA-206 has

been made of vibration and moisture-resistant birch plywood. All cutting and milling work, as well as drilling operations, has been developed by computerized numeric control machinery (CNC) which allows us to assure perfect and accurate assembly.

The black finish, which uses totally ecological water-based acrylic resin paint, provides an excellent external protection.

We also include a 1.5mm steel Front grille with 5mm acoustically transparent foam.

Each unit incorporates rigging for safe, easy and quick flying or stacking.

2.5. MA-206/D System D=DSP version of MA-206 with independent amplification on each way and internal

processing through DSP included. Transducers and waveguides are those explained

in 2.2 and 2.3. The Class D amplification modules are 1000 W for the low way and 500 W for the high

way. Their high efficiency (almost 90%) allows their location on the lower panel without the necessity of forced cooling. We eliminate any fan or any other auxiliary device which may fail because of extra mechanical work.

The DSP control software allows:

• Parametric equalizations

• Delays

• Gain control for each way

• Crossovers up to 24 dB/Oct

• Limiters for each way

The adjustments can be done through a rear screen placed on each MA-206/D or

through PC with RJ45 connectors.

3.MAW-115 SYSTEM DESCRIPTION Amate Electroacústica offers the MAW-115/D: Active version with DSP control

This model is a Bass Reflex unit that contains one 15" Neodymium Woofer.

3.1. 15" Neodymium Loudspeakers

The 15" transducers used, which are probably the best ones on the current market with these features, offer a clean, undistorted low frequency reproduction at very high sound pressure levels. This low distortion and unmatched quality are further and significantly improved by the double demodulating rings (DDR) embedded in the pole piece of the magnetic structure. These are designed to dramatically reduce the intermodulation and third order distortion while also improving transient response. Excellent heat dissipation is achieved by incorporating external magnetic configuration.

3.2.Finish

The MAW-115D has been made of vibration and moisture-resistant birch plywood. All

cutting and

milling work, as well as drilling operations, has been developed by computerized numeric control machinery (CNC) which allows us to ensure perfect and accurate assembly.

The black finish, which uses totally ecological water-based acrylic resin paint, provides an excellent external protection

We also include a 1.5mm black-painted steel grille with acoustically transparent foam on the front side.

5.-SYSTEM CONNECTIONS

As an example, let us start with an 8 MA-206 cabinet configuration (including 2 units of MA-206/D and 6 units of MA-206/P). All the rest of configurations may be deduced

from this base system.

Each set includes a FACTORY PRESET which can be modify through the control software or the in-built rear digital screen.

A sound system must be switched on sequentially. Firstly switch on the sound sources such as CD players. Then, the mixer and finally the self-powered cabinets. If you are using several units it is recommended that you switch them on sequentially

one at time. If you are not using MA-206 in combination with low frequency reinforcement units,

plug the output of mixer into the first unit of MA-206/D Input. (Fig.9. INPUT SIGNAL

(C)).

Daisy chain the first unit of MA-206/D with the second unit of MA-206/D through LINK INPUT SIGNAL connectors.

Feed the first unit of MA-206/D through AC INPUT connector (Fig.9.(E)). and simply daisy chain the second unit of MA-206/D through AC STACKING OUTPUT.

Connect the 3 signal outputs from the MA-206/D (Fig.9.(H)) to the Speakon inputs of each MA-206/P.

For the DSP control via PC/Laptop simply connect the PC output to the RJ45 INPUT (Fig.9.(A)) of the first MA206/D unit and daisy chain the signal to the second of MA206/D unit through RJ45 LINK (Fig.9.(B)).

6.FLYING SYSTEM

Flying an MA system is easy, fast and secure. To perform any operations related to

flying the system, read the present document, and act on the warnings and advice given.

Only experienced installers with adequate knowledge of the system and local safety regulations should fly speaker cabinets.

It is the user's responsibility to ensure that the systems to be flown and the flying accessories (such as chains, eyebolts, lock pins...) comply with state and local regulations. They should be regularly inspected and replaced if in doubt.

When flying enclosures from ceiling support structures, extreme care should be taken to assure the load bearing capabilities of the structures. Do not fly systems from unsafe structures.

All flying accessories that are not supplied by Amate Electroacústica are the user's

responsibility. Use at your own risk.

Remember that no risks should be taken with regards to public safety.

6.1.Description Each MA-206 cabinet includes flying structures on the front-lateral sides and on the

back side. These structures are manufactured from stainless steel; they are affixed with special crop resistant screws. The front structures are used to vertically join the cabinets; the back structures are used to vertically join the cabinets and to tilt them.

Angles can be changed from 0º to 8º. To safely lock the guides, the lock pins supplied must be used.

Page 17

Amate Electroacústica,s.l.

MA206/MAW115.Version 1.3 Nov 08

To tilt the cabinets, the back structures and the back guide must be used.

The available degrees are 0º, 1º, 2º, 3º, 4º, 5º, 6º, 7º and 8º.

To fix the guides to the holes, highly resistant 8mm pins are used with ball safety lock.

Fig.16. Flying structures (general view)

Fig.17. Back guide with graduation

Fig.18. Ball Lock Pins

The flying Frame is made from stainless-steel and is designed to handle great loads. It includes a centre and lateral bars to reinforce the whole structure. The centre bar has a series of holes that provide a pickup point for the steel chain slings or the hoists. The pickup point chosen will determine the tilt angle of the whole array

system.

A shackle is included on the Flying Bumper Kit. It can be fitted into any of the centre bar holes (depending on the gravity centre of the configuration). The shackle can be also hung on the elevation motor of the system.

Fig.20. Flying structure We recommend the use of a safety cable on the shackles' hole. (see Fig.23). You

should coil the cable around the shackle to avoid any incident in case of unscrewed guides.

7- OVERVOLTAGE PROTECTION

The MA206D, MAW115D and MAW215D/2K models include over voltage protection.

An electronic circuit compares the input voltage with a reference value on the AC Input connector (MAINS). When the input voltage is higher than 250 Volts the circuit starts to work, blocking the input voltage until its value returns to its correct limits (230V +/- 10% ).

When the Overvoltage LED lights (in RED) (Fig.9. LED OVERVOLTAGE (G), Fig.12. LED OVERVOLTAGE (G), Fig.14. LED OVERVOLTAGE (G)), the cabinet stops working (or works intermittently) until the correct voltage values are reached again.

• Make sure that the cabinet is plugged in.

• The Fuse is blown. Replace the fuse on fuse holder with one of the same type. This

replacement must be done by specialized people as the fuse is set inside the amplification

modules. AC Voltage may be controlled by rotating the Fuse 90º (230V or 115V). See fuse

holder for more information. No Sound

• Check that the mixer, sound source and processor is sending signal to the unit.

• Check that the cable from the mixer, sound source or processor to the units is correctly

connected. Replace the cable if defective.

• Make sure the output volume (gain) control on the mixing console and processor is sufficiently turned up to drive the inputs of the speakers.

• Make sure the mixer and the processor do not have a Mute on.

Distorted sound

• The system is overloaded and has reached maximum power. Turn down the mixer's output or the channel's gain.

Poor bass performance

• Check the polarity of the connections between the mixer/processor and the MA-206

amplifiers. If you have inverted any of the Pins (1,2 or 3) in one of the extremes of the wire, the losses may be extremely high.

Noise and Hum

• Make sure all connections to the active units are in good conditions.

• Avoid routing the signal cables near AC cables, power transformers, or EMI-inducing

devices.

• Check if there is any light dimmer on the same AC circuit as the cabinet. Connect the sound system to a different phase than the lights.

VERTICAL: 220V

HORIZONTAL: 115V
