The required signal processing, accomplished by DSP (digital signal processing), involves parametric equalization, signal delay, frequency filtering, gain, and limiting. These parameters are individually adjusted by the DSAPilot for each transducer in each loudspeaker. The available DSP resources provide a broad range of possible coverage patterns and SPL control over distance as well as the “voicing” required for exceptional music reproduction.

The DSA allows multiple loudspeakers to be arrayed as a cluster at a single location. This allows a greater range of beamwidths, SPL, pattern control, and low frequency output than a single DSA loudspeaker can provide. The DSAPilot treats the cluster as if it were a single loudspeaker, precluding the complexities normally associated with designing clusters.

The DSAPilot, used to set the loudspeaker signal processing parameters, is based on software originally developed by EAW engineers for the KF750, KF760, and, in particular, the KF900 Series products. These products require precise but variable pattern control and a high degree of fidelity for speech and music in projects that range from small houses of worship to the newest super-stadiums. Sophisticated mathematical algorithms were developed to determine the necessary adjustments to achieve these results for both multiple transducers and multiple loudspeaker clusters. This math was incorporated into highly user-friendly software. Thoroughly tested and refined in successful, real-world applications, these techniques have been applied to the DSA Series to achieve the same high degree of pattern control, musicality, and ease of setup.

Though highly complex, the DSAPilot’s mathematics work behind the scenes. Because of this, the DSAPilot makes adjusting the signal processing deceptively simple. In fact, no acoustical knowledge is required to set up and adjust one or multiple DSA Series loudspeakers. The only information needed for the DSAPilot to perform its magic is the physical layout of the listening area, loudspeaker mounting location, and desired coverage area.

While the DSA250 is designed as a full-range loudspeaker, addition of the companion DSA230 increases directionality, and output at lower frequencies. DSA230s extend directional control to lower frequencies using classical line array theory by extending the length of the overall array. This is done by mounting the DSA230 directly below or above a DSA250 to form a longer line of low frequency transducers. In addition, the increased number of low frequency transducers couple to increase the low frequency output capability.

A major benefit of the DSA Series is achieving desired down angle coverage

 

from a line source that is mounted flat to a vertical surface. The inclusion

 

of power amplifiers and dedicated signal processing to each transducer

 

provide the DSA Series with performance and capabilities well beyond

 

those of typical multi-way loudspeakers and traditional, voice-range line

 

arrays. The DSA Series can provide much better directional control, higher

 

output, and wider frequency response at less cost. Significantly smaller

 

sizes and weights, plus straightforward mounting and wiring options pay
