- Page 3 Amate Electroacústica,s.l. 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...
- Page 4 Amate Electroacústica,s.l. 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.
- Page 5 Amate Electroacústica,s.l. 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;...
- Page 6 Amate Electroacústica,s.l. 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.

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.
- Page 11 Amate Electroacústica,s.l. 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.

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. - Page 13 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;...

Page 19: Overvoltage Protection
Amate Electroacústica,s.l. 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% ). - Page 20 Amate Electroacústica,s.l. 7.TECHNICAL SHEETS MA-210/D7 Line Input (Balanced) Impedance 1.8 V 10k ohms Mains 230V +/- 10% Overvoltage Protection at 250V Consumption at Maximum Power Frequency Response LF Usable bandwidth 80 Hz - 2 kHz (-10 dB) (1W, processed) HF Usable bandwidth 2 kHz - 20kHz (-10 dB) (1W, processed) Total Usable bandwidth...
