DASaim

DASaim, a FIRmaker technology for advanced line array systems, is a high-tech solution that designs customed FIR filters for each cabinet in an array.

 

With DASaim, the magnitude and phase response of every frequency of each cabinet can be individually adjusted. The performance of your arrays can easily be upgraded to a new level, providing a more adaptive and flexible audio solution for your live events and installations.

 

DASaim makes the future of audio available today. Thanks to the powerful DSP units employed, no external multi-channel processors or processed amplifiers are needed. This key advantage of the DAS Audio systems over others equates to a very significant reduction in cabling costs and set-up time. This delivers a host of new features to arrays for enhanced flexibility and versatility. Once the array has been installed with DASaim, the vertical dispersion pattern of the array can be adapted to your needs without physically having to change the array’s height or splay angles. Here is an example of the typical behavior of a line array system. After setting the height and splay angles of the cabinets, variations in the SPL with distance and differences in tonal balance from front to rear are perceivable.

 

Optimizing the system’s performance is a now a simple process. The acoustic predictions and FIR filter designs are ready to be performed after introducing precise venue information into EASE focus, providing a fast and easy way to compare the results of different filter sets.

 

Finally, simply export the FIR filters from EASE focus to ALMA/DASnet to send them directly to the cabinets in just a few clicks. With DASaim, the systems can be configured to match the desired performance objectives, and being able to adapt the vertical dispersion pattern of the array makes it possible to control the decrease in SPL level at a distance. Uniform frequency response from front to back can also be achieved. We can lower the SPL created by the array if there is no audience there.
