In live sound systems, tuning a line array using DSP (Digital Signal Processing) is a critical step in achieving consistent, clear sound from the stage area all the way to the back of the venue.

When implemented correctly, DSP tuning helps the system reach optimal audio performance, minimizes unwanted reflections, and ensures a uniform listening experience across all audience areas.
