Models:

  • Distributed System Design [DSD]

Overview:

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.


Installation: 

DSD is only available for Windows

 

 

  • Go to the Distributed System Design product page, download and install it.

How to Use It: 

  1. Open the application from your start menu. 
    The following screen will appear:

  1. Click on Distributed System  Design > New Design

  1. Name your project and choose the dimensions (ft) of your room.

For pendant speakers choose the height from the floor to the grill, not to the ceiling.

 
  1. Choose the Speaker Mode along with the configuration it will be set to (8ohms or 70v).
  2. Next, choose the intended type of array [square or hexagonal] and the coverage for the room. 
    The bigger the coverage, the more speakers it will use with a smaller dB level variation between sections.

  1. When all the parameters have been filled, click OK. A top view plot will show up with a proposed distribution.

 

If you wish to modify any parameters of your design, simply click on Revise Design on adjust accordingly.
