Chapter 1 Introduction The DSA250i full-range and DSA230i voice-only or low frequency system are small format, column-type loudspeaker systems with a user-variable vertical beamwidth. The loudspeakers, known as modules herein, can be used as singly or combined in multiples as clusters. The easy-to-use DSAPilot software allows accurate adjustment of a module's or a clusters's coverage area from a fixed, vertical mounting location. In addition to excellent vocal performance, the DSAi Series is ful

2.3 Returning Products to EAW If the loudspeaker must be returned to EAW, contact the EAW Service Department for a Return Authorization (See Chapter 7). Use the original shipping carton and packing materials. If the shipping carton is lost or damaged, contact EAW for a new carton, for which there will be a small charge. EAW will not be responsible for damage caused by inadequate packing when returning the loudspeaker for service. All units returned must have a factory Return Authorization Number

3.6 Physical Installation LED INDICATOR 3.6.1 ORIENTATION ON FRONT SURFACE AC MAINS CONNECTOR 1. When installing the enclosure, there is a correct “top” and “bottom”. This cannot be assumed from the physical appearance. Instead, orientation depends on application and desired acoustical performance determined using DSAPilot. 2. Ensure the enclosure is oriented correctly by verifying which ends are supposed to be the top and bottom for the intended application. The Signal End is the end wit

3.7 Signal Processing The vertical coverage is determined by programming the module’s digital signal processing. Use DSAPilot to determine the desired coverage. DSAPilot calculates and optimizes the signal processing required to achieve the desired results. High pass/low pass filters, parametric EQ, delay, and gain are user adjustable for each of the two inputs.

4.3 Applications The DSAi Series provides a significant advance for cost-effective implementation of line array technology in a variety of applications. As is typical for line arrays, the DSAi Series is an excellent choice for voice- only applications. However, unlike typical voice-only line arrays, the DSAi Series can also provide the wide frequency range, fidelity, and output levels needed for excellent music reproduction. This significantly extends its range of applications to a wide range of

Multiple DSAi modules arrayed as a cluster at a single location allows a greater range of beamwidths, SPL, pattern control, and low frequency output than a single DSAi module can provide. DSAPilot treats the cluster as if it were a single loudspeaker, precluding the complexities normally associated with designing and tuning clusters. The major advantage of DSAi its radiation pattern which is quite different than simply angling down a loudspeaker with the same horizontal and vertical beamwidths.

4.5 DSAPilot DSAPilot, used to set the module 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 required 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 calculate the signal processing to achieve the

Chapter 5 Installation This chapter details the requirements for installation. Specific details may require some variation depending on the particular situation. However, the basic requirements are the same in all cases. Module refers to either a DSA230i or DSA250i. Cluster refers to any of the permissible arrangements of single or multiple DSA230i or DSA250i modules as defined in DSAPilot. Whether they consist of a single or multiple modules, all DSAi clusters function as a single loudspeaker.
