Stetsom STX2448 Floating 4-Channel DSP Crossover & Equalizer

The new STX2448 Floating processor brings new design and state-of-the-art features, designed to improve and optimize the audio system in a vehicle. It acts as a digital signal processor (DSP), allowing fine, personalized adjustments to the characteristics of the audio played through the car’s sound system. These adjustments include equalization, crossover, time delay, and other parameters that influence audio quality.
