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 D e s c r i p t i o n

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

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

Model DSA250 is a full range loudspeaker. Model DSA230 can be employed as a voice-only loudspeaker or as low frequency loudspeaker to supplement a DSA250’s low frequency output and pattern control.

NOTE: Using the 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 loudspeaker cluster is also provided.

Distances up to 2 ft / 0.6 m are for connecting multiple loudspeakers in a single cluster while distances over 2 ft / 0.6 m are for connecting physically distributed clusters.

Up to 1 ft / 0.3 m: Supplied Cat-5 Signal Link Cable

Connect between Signal Link jacks (Neutrik® EtherCon®) on vertically adjacent loudspeakers within a multi-loudspeaker cluster.

Up to 2 ft / 0.6 m: User-supplied, Cat-5 Ethernet crossover cable

Connect between Signal Link jacks (Neutrik® EtherCon®) on horizontally adjacent loudspeakers within a multi-loudspeaker cluster.
