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.

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

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.
