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.
Chapter 1 1.1 Safety Safety Precautions The terms “Caution,” “Warning,” and “Danger” are used throughout this manual to alert the reader to important safety precautions.

Chapter 4 4.1 Description 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.

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 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.
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.

5.3 AC Mains Power Connection This section details the requirements for the AC mains which is the AC power connection required by each DSA loudspeaker. 5.3.1 A C M A I N S S U P P LY CAUTION: Read all cautionary notes concerning electrical power in Chapter 1. Each DSA Series loudspeaker is rated for a particular nominal AC Mains voltage: 115 V or 230 V.
The LED should then go off. See Section 6.1.2 for other LED indications. If it is desired to completely power off (de-energize) the loudspeaker, a conveniently located AC mains disconnect must be supplied or the power cable must be unplugged from the loudspeaker or the AC mains supply. The PowerCon connector is a locking connecter. To lock, twist 1/4 turn clockwise after fully inserting into the jack. It is recommended the connection be made at the loudspeaker before connection to the AC mains supply.
5.5 Physical Installation This section details the physical requirements and methods for installing the loudspeaker. Specific mounting procedures detailed herein may require some variation depending on the particular situation. However, the basic methodology is the same in all cases. Basic installation tasks include: Installing the Enclosure and Wall Brackets Mounting the loudspeaker 5.5.
orientation and, when multiple loudspeakers are used, the correct location of each. For the DSA250, the Power End is the end with the HF subsystem and Signal End is the end with the LF subsystem. 5.5.3 M U LT I P L E LO U D S P E A K E R S A N D C LU S T E R C O N F I G U R AT I O N S CAUTION: Only clusters included in DSAPilot may be used. Any other configurations will result in poor to unusable performance. Several cluster configurations are shown in Figure 5.5.3.

That means for a steering angle of 0 degrees “on-axis” is the physical center of the cluster. The elevation entered into DSAPilot refers to this point.
8.5 in MIN IMUM TO CEILING Critical Dimensions: 1. Spacing between the Wall Brackets for a single loudspeaker must be within 0.1 in / 3 mm of the dimensions in Figure 5.5.7a. In order to lift a loudspeaker onto its wall brackets, spacing between the top wall bracket and ceiling, or other overhead obstruction, must be 8.5 inches minimum. NOTE: 8.5 inches allows only 0.25 inches extra clearance. DSA250 38.1 in 968.3 mm DSA230 23.9 in 606.3 mm Figure 5.5.7a Wall Bracket Spacing 2.
5.5.8 E N C LO S U R E B R A C K E T I N S TA L L AT I O N Insert each supplied Enclosure Bracket into its slot near each end of the enclosure, verifying the proper orientation of the enclosure. Insert a supplied 3/8-16 x 2 in Enclosure Bracket Bolt with its lock washer into each bracket bolt hole in the enclosure. Thread each bolt into the weld nut on its Enclosure Bracket and hand-tighten.
1/4-20 X 3 LG HEX HEAD SCREW & LOCK WASHER 1/4-20 WELD NUT 1. Install at least one of the supplied 1/4-20 X 3 in Retainer Bolt with its lock washer through the side of either the top or bottom Wall/Enclosure Bracket and snugly tighten. The bolt threads into a weld nut on the side of the Wall Bracket. This Retainer Bolt prevents the enclosure from being lifted off the Wall Brackets without first removing the bolt. Note that the Retainer Bolt does not “clamp” or support anything.
5.6 Initial Set-Up 5.6.1 V E R I F Y LO U D S P E A K E R O R I E N TAT I O N A N D P O S I T I O N LED INDICATOR Using the DSAPilot, and with communications established with the loudspeakers, click on each loudspeaker in DSAPilot. The LED in both the DSAPilot graphic and on the actual loudspeaker will illuminate. Ensure that the physical orientation and position of each loudspeaker corresponds to that shown in the DSAPilot graphic. See the DSAPilot help file for further information.
Chapter 6 Operation The general operation of a DSA loudspeaker is similar to the operation of most loudspeakers. Initial system set-up and overall tuning adjustments detailed in this Chapter must be made using DSAPilot. For details about using DSAPilot functions refer to the DSAPilot Help File.
2. Input Clip: If this indication is enabled, random flashing shows that the audio input signal is clipping the A to D converters at the input. To correct this condition, reduce the input signal level at the source. Because the input gain is after the A to D converters, the DSA input gain adjustment will have no effect on this condition. NOTE: This is likely an unusual condition because the LED will respond only if the input signal levels are greater than +24 dBu.
6.2 Operational Check List To operate a DSA loudspeaker, pre-performances checks and adjustments should be made. In typical permanently installed applications, these checks would normally be one-time, set-up adjustments that may only need to be periodically verified. All of these steps require using DSAPilot. 1. Set the Power Management function as appropriate for your application. 2. Select each cluster in the DSAPilot design and verify the LED indicator illuminates on the corresponding physical cluster.
6.3.3 O P E R AT I O N Operate DSA similarly to any other loudspeaker. This normally involves setting the source levels to achieve the desired output as well as applying external equalization or other signal processing to achieve certain desired results. DSA’s internal signal processing, set using DSAPilot, should not be used for in performance adjustments. 6.4 Operational ‘DOS’ and ‘DONTS’ 6.4.

Distorted sound Excessive levels Using the DSAPilot, monitor the DSA signal path to check for clipping at all monitoring points. Distorted sound Bad input signal Use a substitute amplifier and loudspeaker to check the quality of the input signal to the DSA Series loudspeaker.
8.3 EIA-485 Network EIA-485 network cabling has certain limitations that these notes summarize. Improper set-up of an EIA-485 network can result in faulty or no operation. To use EIA-485 network configurations or cabling schemes not addressed in this manual, consult a qualified network professional. 8.3.1 CABLING NOTES: 1.
8.3.2 T E R M I N AT I O N N O T E S : 1. The DSA Terminate Switch connects a 120 ohm resistor as a load on the EIA-485 cabling. 2. Normally, USB to EIA-485 or RS-232 to EIA-485 converters also have a termination resistor connected as a load on the computer end of the EIA-485 cabling. If optional, this termination should be switched on. Both this termination resistor and the one in the loudspeaker at the far end of the EIA-485 cabling from the computer are required to ensure proper network operation. 3.
