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:
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.
Amate Electroacústica,s.l.
MA210/MAW215.Version 1.11 Feb 09 4
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.
MA210/MAW215.Version 1.11 Feb 09 5
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 tilt angle (between cabinets) is 6º.
Fig.4. Tilt angle between cabinets (6º 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

In the near field region (Fresnel), the wavefront is cylindrical and waves only expand
on the horizontal plane (120º in MA-210). 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 120º and the vertical
coverage is defined by the frequency and the height of the array.

Calculation
An 8-cabinet array has a near field extending to 19 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-210 SYSTEM DESCRIPTION
Amate Electroacústica offers one version of its MA-210 System.
MA-210/D7: Active version with DSP control
It is a 2-way unit that uses two 10" for the low-mid frequencies (with front phase-plug)
and two 1" compression drivers (44mm voice coil) coupled to property waveguides
for the high frequencies. We also introduce a low frequency reinforcement cabinet
called MAW-215/2, which is offered in the active with DSP version (MAW-215/D/2K).
2.1.Why this "strange" front design?
The MA-210 shape is "trapezoidal-triangular". The "baffles" are V-shaped, forming a
120º angle between them (horizontal coverage of the system).
Fig.8. Dimensions of MA-210
Amate Electroacústica,s.l.
MA210/MAW215.Version 1.11 Feb 09 8
With this geometry we avoid stationary waves within the upper and lower sides of the
enclosure and we reduce cancellations on the total frequency response of the
system.
2.2. 10" Neodymium Woofers with Phase-Plug
The low-mid way includes two 10" Neodymium woofers, with 2.5" voice coil and with
copper ring to align the impedance. This woofer is the perfect ratio between a wide
response and a small-sized transducer. We achieve an optimum performance on the
frequency range of the voice.
Each loudspeaker is coupled to a phase plug. We widen the frequency response on
the "higher" mid range and increase the total sound pressure level through its
radiation areas.
2.3.1" Compression drivers with waveguide
The high frequency way includes two 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-210 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 2mm black painted steel grille with transparent foam on the front
side.
Each unit incorporates rigging on its side for safe, easy and quick flying or stacking.
2.5. MA-210/D7 System
D=DSP version of MA-210 with independent amplification on each way and internal
processing through DSP included.
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 rear panel .
The DSP control software allows:
Amate Electroacústica,s.l.

3.MAW-215 SYSTEM DESCRIPTION
Amate Electroacústica offers one version of its MAW-215/2 Low frequency
reinforcement System.
MAW-215/D/2K: Active version with DSP control
It includes two 15" Neodymium Woofers and they are acoustically controlled by the
volume of their three chambers. Despite its compact size, we obtain an excellent
performance with very low levels of distortion.
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-215 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 2mm black-painted steel grille with acoustically transparent foam on
the front side.

Each unit incorporates rigging on its side for safe, easy and quick flying or stacking.
3.3. MAW-215/D/2K System
D=DSP version of MAW-215 with in-built amplification and internal processing through
DSP included.
The Class D amplification modules are 1000 W (two units, total 2000 W). Their high
efficiency (almost 90%) allows their location on the rear 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
• Crossovers up to 24 dB/Oct
• Limiters
The adjustments can be done through a rear screen placed on each MAW-215/D/2K
or through PC with RJ45 connectors.

4.-SYSTEM CONNECTIONS
4.1.Active Systems with DSP Control MA-210/D7
As an example, let us start with a 4 MA-210/D7 cabinet configuration. All the rest of
configurations may be deduced from this base system.
Each cabinet 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-210/D7 in combination with low frequency reinforcement units,
plug the output of mixer into the MA-210/D7 Input. (Fig.9. INPUT SIGNAL (C)).
If you have more cabinets, simply daisy chain them through LINK INPUT SIGNAL
connectors.
Feed one unit through AC INPUT connector and simply daisy chain the others through
AC STACKING OUTPUT. The maximum number of units than can be linked this
way is 4 (including main unit).

5.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.
5.1.Description
Each MA-210D7 cabinet includes two structures on each side of the enclosure, one
on the front-lateral side and the other on the back-lateral side. These structures are
manufactured from 3mm stainless steel; they are affixed to an internal plate with
special crop resistant screws. There is a guide (front guide) assembled on the frontlateral structure (which is used to vertically join the cabinets); a second guide (back
guide) assembled on the back-lateral structure is used to vertically join the cabinets
and to tilt them.
Amate Electroacústica,s.l.
MA210/MAW215.Version 1.11 Feb 09 14
Angles can be changed from 0º to 6º. To safely lock both guides, the lock pins
supplied must be used.
To tilt the cabinets, both the back-lateral structure and the back guide must be used.
Fig.13. Lateral structures (general view)
Fig.14. Back guide with graduation
Fig.15. Ball Lock Pins
To fix the guides to the holes, highly resistant 8mm pins are used with ball safety
lock.
To fly more than 6 units of MA210D7 use the TA-210HD Frame. It is made from
Stainless Steel and is designed to handle great loads. It includes a centre bar to
reinforce the whole structure. The bar has a series of holes (20 mm) 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.
Amate Electroacústica,s.l.
MA210/MAW215.Version 1.11 Feb 09 15
Fig.16. TA-210HD Flying Frame
The TA-210SD Frame can be used for flying up to six MA210D7 cabinets.
A shackle is included on the Flying Frame 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.17. Flying structure
We recommend the use of a safety cable on the shackles' hole. (see Fig.30). You
should coil the cable around the shackle to avoid any incident in case of unscrewed
guides.

5.2. MA-210 Flying
Use the back guide to choose the desired tilt angle (0º, 0.5º, 1º, 1.5º, 2º, 3º, 4º, 5º and
6º). Set the back guide between the back lateral structures of the cabinet that is
placed above. Lock the guides with the safety pins.

5.3. MAW-215D/2K Flying
It is not possible to aim low frequency reinforcement units. Units are joined through
the built-in guides of each cabinet.
Fig.21. MAW-215D/2K Flying
5.4. MA-210D7 +MAW-215D/2K Flying
It is useful to hang low frequency reinforcement units on the top of the system, as
they are the heaviest enclosures. Place the subwoofers as has been explained in
section 5.3. Join the last unit of MAW-215D/2K onto the first unit of MA-210/D7
through the built-in steel structure on the subwoofer.
If you want to place the first unit of MA-210/D7 with a 0º degree (flat cabinet), please
select 6º position on its back guide.
Follow Section 5.2. to hang the rest of MA-210/D7 units (choose between a flat line
array or a curved line array)
We recommend 3-4 units of MAW-215D/2K for every 8 units of MA-210/D7.

6- OVERVOLTAGE PROTECTION
The MA210D7 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.11.
LED OVERVOLTAGE (G )), the cabinet stops working (or works intermittently) until
the correct voltage values are reached again.

8.TROUBLESHOOTING
No Power
• 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-210/D
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.

9.PRESETS
This manual is aimed to describe some of the Presets that are recommended from
our factory and that will be included in all the cabinets that form your MASTER
AUDIO Line Array System.
The Presets are internal configurations that have been loaded to a memory (EPROM)
on each box and that contain information regarding the Crossover Frequencies,
Parametric Equalizations, Delays, Gains on each way...
These Presets cannot be erased but they can be externally modified through our DSP
Controller software or through the small keyboard placed on the rear side of the box.
Then, any user can create their own Presets.
Some of the parameters cannot be changed by the user (for example, the crossover
frequency of the mid and high way in MA210D). We try to avoid some damages on
the transducers in case of. inappropriate or "dangerous" frequencies of cut.
This manual describes the features of the following product version:
EPROM MA210D: v1.0.1
EPROM MAW215D2: v1.0.0
(You can check the version on the LCD placed on the rear side of the cabinet)
Should you own different product versions, there may be differences between the
actual product and the description written here.
