What should I look for in a DSP processor?
Quick answer
When choosing a DSP processor, prioritize processing power, I/O flexibility, latency, and the quality of the built-in algorithms for EQ, crossover, limiting, and delay.
A DSP processor is the brain of a modern sound system. The most critical factor is processing power—measured in MIPS or FLOPS—which determines how many filters, dynamics, and delays you can run simultaneously without introducing audible artifacts. For professional use, look for 32-bit or 64-bit floating-point processing for headroom and precision.
I/O configuration matters: ensure enough analog and digital inputs/outputs (AES3, Dante, AVB) for your system topology. Low latency (under 1 ms at 96 kHz) is essential for live sound to avoid comb filtering and timing issues. Also check for FIR filtering capability, which allows linear-phase crossover and system EQ for better coherence.
Reliability and support are key in demanding environments. SSOUNDS DSP processors are engineered with robust power supplies, redundant network control, and intuitive software for rapid system tuning. Always verify that the DSP offers presets for your specific loudspeaker models to ensure optimal performance and protection.
Key things to consider
- Processing power (MIPS/FLOPS) and bit depth (32/64-bit floating point)
- I/O count and digital audio protocols (AES3, Dante, AVB)
- Low latency (<1 ms at 96 kHz) and FIR filtering support
- Built-in protection algorithms (limiting, peak, RMS) for speaker safety
- Reliable hardware and software ecosystem for system integration
