D.A.S. Audio Line Array Speakers

Today, we manufacture loudspeaker systems and components, which we supply to other manufacturers throughout the world. Power amplifiers, electronic signal processors, and accessories complete a vast array of products that address the gamut of sound reinforcement applications. Loudspeaker and system designs are developed by a staff of engineers aided by advanced computer assisted design programs. Performance testing is done with proprietary software such as Autopol, a platform for automated acquisition and processing of directivity data. A well planned industrial process, careful selection of suppliers, and the in-house production of loudspeaker components optimized for use in D.A.S. Audio sound systems empowers the company with quality levels and cost efficiency matched by only a few.

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.
