AERO12A Line Array Speakers

...distortion. Impressively compact in size and light in weight, its high power density of over 20 W per cubic inch promotes an amplifier design that requires much less space, reducing the overall cabinet size and in turn, the total cabinet weight-an important attribute for flown systems. Signal processing is accomplished by way of a powerful 24 bit DSP providing unparalleLED Control over critical signal parameters. Digital Finite ImPulse Response (FIR) filters are used in the signal processing of the Aero 12A.

The Aero 12A incorporates a D.A.S. 12LN4C, 12" low frequency transducer employing a 75 mm (3") voice coil and neodymium magnet motor assembly. High frequency reproduction relies on the exceptional characteristics of the new D.A.S. M-75N neodymium compression driver designed for use in applications where high SPL and low distortion are required. A pure Titanium diaphragm featuring a 75 mm copper-clad, aluminium flat-wire voice coil yields high sensitivity, low distortion and extended frequency response.

The easily portable and rugged enclosure is manufactured using birch plywood and finished with a durable black paint. The captive rigging system splay angles range from 0º to 10º and can be adjusted in 0.5º increments from 0º to 3º and 1º increments from 3º to 10 º allowing a wide range of column curvatures to be accomplished.

Line Array Speakers

Line array speakers make up a loudspeaker system to create a sound source that produces an evenly distributed sound output. The driver of each line array element is close enough to the driver of the next element to create constructive interference. The resulting sound waves go farther than sound waves from traditional loudspeakers. Line array systems date back to the early days of research in acoustics. Many old town halls and public venues still have old line source boxes which were found to project voice well though they are much smaller than horn-loaded speakers. These days, line array speakers use different drivers for high-, mid- and low-frequency passbands that must be in line. Each enclosure must be set up closely to form columns composed of these drivers. To increase the frequency range and maximum sound pressure, the number of drivers per enclosure must be increased. The orientation of line array speakers may vary. Vertical arrays are excellent for focusing sound at audiences without wasting output energy on ceilings or empty air above the audience because of its very narrow vertical output with a normally-wide horizontal pattern. On the other hand, horizontal line arrays have a very narrow horizontal output with a tall vertical pattern. For hanging concert speakers which are usually part of a concert reinforcement system, enclosures are set up together using a specialized rigging hardware and they hang from a single point. These line array speakers are curved backward at the lower portion so that the sound will reach more audience.
