4.4 Engineering Design The core acoustical design of the DSA Series dates back to the late 1930s in Harry Olson ’ s book, “ Acoustical Engineering ” . He show ed that, by using different signal delay s on the input to each transducer in a simple line array , the array ’ s main output lobe could be effectively “ steered ” . While this co[...]

The required signal processing, accomplished by DSP (digital signal processing), involv es parametric equalization, signal delay , frequency filtering, gain, and limiting. These parameters are individually adjusted by the DSAPilot for each transducer in each loudspeaker . The a vailable DSP resources provide a broad range of possible co verage patt[...]

additional benefits in reduced installation costs and operation. The flexibility of the DSAPilot to automatically optimize the acoustical performance for multiple DSA Series loudspeakers in a single larger space further enhances their advantage o ver traditional solutions . 4.8 Designing DSA Sy stems DSA loudspeakers can be used individually , in m[...]
