Some user feedback from Sinbosen customers

Sinbosen recently launched a new digital audio processor, the LA548. Like the Sinbosen LA448, the LA548 is a 4-input, 8-output DSP digital amplifier; however, the LA548 features AES, Auto-EQ, and Auto-FIR capabilities, though it lacks Wi-Fi functionality.

When using the DSP D4-2000 and DSP D4-3000 to drive the TN-24 and BN-30 combination, precise DSP tuning of crossover, delay, and limiting ensures stable and reliable performance results.

Sinbosen offers a custom white version of the KA15 15-inch line array speaker, suitable for small venues such as home theaters, weddings, and churches.
