Distributed System Design (DSD) v3.6.2 v3.6.2 (Windows)

Note: this is an old version. The current version is: Distributed System Design (DSD) v3.7 (Windows). ×

The DSD program is a system design engineering tool that calculates and displays the number of ceiling and/or pendant loudspeakers needed to cover a room.

The user inputs a rectangular room with the approximate floor space of their project, along with the ceiling height (or trim height for pendant speakers). They select a starting-point loudspeaker and tap setting, and a density (to set the allowable sound level variation within the space). The DSD program computes the resulting number of speakers that are required for covering that listening space, along with a general layout in rows and columns and the target spacing distance between speakers. It computes the resulting performance parameters: Maximum continuous SPL for music and/or speech, maximum continuous peak SPL, expected level variation within the space, and the recommended amplifier power to utilize for powering the system. The Subwoofer Utility suggests a model and quantity of subwoofers to go with the system for instances where subwoofers are desirable.

DSD allows the user to change the design for “what if” scenarios: What will happen if we change the design to a different loudspeaker model, to a different tap setting, to a different density factor, etc? What happens if we trim the pendant speakers at a different height? What impact would different changes have on the number of speakers required, the layout distance between speakers, the resulting sound level, the level variation throughout the space, the required amplification, etc?

DSD gives the system designer the information they need for specifying their distributed loudspeaker system design.

Installing -- DSD needs to be "installed" via an automatic installation process. To do so, double-click on SETUP.EXE. If your system doesn't have the Microsoft DOTNET framework, you be prompted to install it automatically.
