K-LA28-DSP Active Digital Line Array

Core Technology

K-LA28-DSP uses customized Beyma 1.7 HF drivers with a horn coverage of (H°×V°) 100°×20° and customized Beyma 8 LF drivers. The angle between the modules can be adjusted accurately to ensure Hi-Fi sound quality and a clear sound dynamic. The K-LA28-DSP can be either suspended vertically (maximum of 12pcs) or stacked.

To ensure that K-LA28-DSP has perfect sound and excellent stability, even at maximum SPL, K-LA28-DSP is with passive 3-way crossover design to make each frequency band handled by independent driver, and decrease the mutual interference between frequency on off-axis. This not only maximizes the efficiency of the driver, but also ensures the good sound dynamic. Moreover, K-LA28-DSP is with built-in DSP processor with 48KHz signal sampling frequency and 56bit precision for more accurate control on the sound. And with the SMPS and Class D technology, K-LA28-DSP is very light weight and very easy for usage.
