Introduction The Digitally Steerable DSA Series Arrays represents EAW’s latest innovation in advanced, acoustic modeling and applied technology in designing loudspeakers. The DSA250 full-range and DSA230 voice-only or low frequency system are small format, column-type loudspeaker systems with a user-variable vertical beamwidth. The easy-to-use DSAPilot software allows accurate adjustment of the loudspeaker’s coverage area from a fixed, vertical mounting location. In addition to excellent vocal p

1.2.1 GENERAL PRECAUTIONS 1. Read and Follow Instructions — Before installing and operating this loudspeaker, read and follow all instructions and safety precautions in this manual and on the loudspeaker. Retain them for future reference. 2. Ventilation — The sides and rear of the enclosure form the heat sink for the internal amplifiers and may reach high temperatures during use. As such, adequate ventilation is required to ensure proper operation. Allow a minimum of 2 inches of clearance betwe

Chapter 3 Quick Start This section provides basic installation requirements. Refer to Chapter 5 for detailed instructions. Loudspeaker refers to either a DSA230 or DSA250. Cluster refers to any of the permissible arrangements of single or multiple DSA230s or DSA250s as defined in DSAPilot. Whether they consist of a single or multiple loudspeakers, all DSA clusters function as a single loudspeaker. 3.1 Description The EAW DSA Series loudspeakers are variable directivity, self-powered line

Chapter 4 Description 4.1 System Overview DSA Series loudspeakers are variable directivity, self-powered line arrays. Each loudspeaker’s vertical beamwidth is determined by the settings of an internal DSP (digital signal processor) and power amplifier for each transducer. This provides complete, on-site control over the range of possible vertical beamwidth patterns. EAW’s Windows-based DSAPilot is used to set the coverage required for each loudspeaker or loudspeaker cluster. The user-friendly D

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 showed that, by using different signal delays on the input to each transducer in a simple line array, the array’s main output lobe could be effectively “steered”. While this concept has certainly been used before, the design of the DSA Series goes far beyond this simple concept. The engineering design for the DSA Series is certainly capable of “ste

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

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 over traditional solutions. 4.8 Designing DSA Systems DSA loudspeakers can be used individually, in multiples, or in various cluster configurations to satisfy a wide range of design requirements. By using different configurations, DSA performance can be
