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.

DSA loudspeakers can be used individually, in multiples, or in various cluster configurations to satisfy a wide range of design requirements. By using different configurations, DSA performance can be varied according to the type of audio program, the frequency range for the vertical control desired, the maximum output levels, the audience location relative to the loudspeaker, and for meeting the requirements for special applications.
Chapter 5 | Installation |
This chapter details the requirements for installing the loudspeaker. Specific details may require some variation depending on the particular situation. However, the basic requirements are the same in all cases.
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.

The configuration and orientation of the loudspeakers will determine where signal, computer, and AC mains cabling must be connected to
CABLE CHANNELSthe loudspeakers. For certain cluster configurations it may be necessary to route cabling from one end of a loudspeaker to another.
The main cable routing method is to use the channels in the heat sink extrusion that forms the rear of the DSA250 and DSA230 enclosures. These channels are intended to be used to route and conceal cabling the length of the enclosure as required. In this way, single wall outlet locations for audio, computer, and AC mains can easily service a single loudspeaker or loudspeaker cluster.
| To facilitate cable routing, clusters have been arranged, where possible, | |
| so the Power Ends of the enclosures are adjacent. This minimizes the | |
