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. Any units received without a Return Authorization Number assigned and written prominently on the outside of the carton will be refused.

Chapter 3

Quick Start

This section provides basic installation requirements. Refer to Chapter 5 for detailed instructions.

Module refers to either a DSA230i or DSA250i loudspeaker.

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.

3.1 Description

DSAi modules are variable directivity, self-powered line arrays. EAW’s easy-to-use DSAPilot provides computer control for the module’s vertical beamwidth pattern. This allows customizing the coverage on-site to fit the application. Modules are controlled via standard EIA-485* or optional CobraNet™/Ethernet networking.

*Also known as RS-485 (Recommended Standard 485)

Model DSA250i is a full range module. Model DSA230i can be employed as a voice-only module or as low frequency module to supplement a DSA250i’s low frequency output and pattern control.

3.2 Audio Signal Connection

NOTE: Using DSAPilot, the two input channels may be summed to mono, used separately, or set up for a priority override function: Audio B overrides Audio A. Equalization, compression, and level are separately adjustable for each input. Overall signal delay for each module and cluster is also provided.

Audio A and B (each): 2-conductor shielded audio cable/supplied Phoenix Contact terminal block plug
