What should I look for in a DSP processor?
Quick answer
Look for high-quality AD/DA converters, low latency, sufficient I/O, robust DSP power for EQ, crossover, delay, limiting, and reliable network control.
When selecting a DSP processor for professional audio, the core criteria are audio quality, processing power, and reliability. High-quality 24-bit or 32-bit converters with low noise and distortion are essential for preserving signal integrity. Latency should be minimal (typically under 1 ms) to avoid phase issues, especially in live sound.
Processing capabilities must include parametric EQ, crossover filters (Linkwitz-Riley, Butterworth), delay alignment, and peak/RMS limiting. Look for enough DSP horsepower to handle your system's complexity without choking. Network control (Ethernet, USB, or proprietary protocols) is vital for remote tuning and monitoring. SSOUNDS DSP processors are engineered with these priorities, offering precise filter shaping and robust control for demanding applications.
Also consider I/O flexibility: balanced XLR or Phoenix connectors, analog and digital inputs (AES3, Dante), and expandability. For touring, rugged build and redundant power supplies add reliability. Always verify that the DSP's firmware and software are stable and user-friendly for your workflow.
Key things to consider
- Prioritize high-quality AD/DA converters with low noise and distortion.
- Ensure low latency (under 1 ms) and sufficient DSP power for EQ, crossover, delay, and limiting.
- Check for flexible I/O (analog, AES3, Dante) and reliable network control.
- Look for robust build quality and redundant power for touring reliability.
- Choose a DSP with stable software and firmware that matches your system tuning needs.
