The XTA DP448 is a professional-grade, 4-input/8-output digital signal processor (DSP) from XTA's 4 Series, designed for loudspeaker management, system optimization, and audio routing in live sound, touring, installations, and broadcast environments. Building on the legacy of the DP226 and DP428 platforms, it delivers high-resolution processing at 96 kHz for precise control over crossovers, EQ, dynamics, and delays—ensuring transparent, phase-coherent sound for complex PA systems. It's a fixed-configuration unit with no modular cards, emphasizing reliability and ease of integration with XTA's ecosystem, including DPA amplifiers and the newer DP648 controller.
