Professional Digital Speaker Processor for PA Systems

The Dragon Stage Digital Speaker Processor Series is designed to optimize the performance of professional loudspeaker systems by providing advanced digital signal processing, loudspeaker management and system protection. Built on a powerful 56-bit DSP platform with 192kHz sampling and 24-bit AD/DA conversion, these processors deliver precise crossover control, equalization, delay and loudspeaker protection for touring, fixed installation and rental applications.

Available in multiple configurations—including 2×4, 2×6, 3×6 and 4×8 input/output options—the DSP processor can easily manage everything from compact conference systems to large-scale concert PA installations.

For complete audio solutions, the processor integrates seamlessly with Power Amplifiers, Line Array Speakers and Subwoofers.
