What should I look for in a DSP processor?
Quick answer
When choosing a DSP processor, prioritize processing power, low latency, high-quality converters, and flexible routing for precise system tuning and protection.
A DSP processor is the brain of a professional sound system. The most critical factors are processing power (to handle complex FIR filters, multiband compression, and delay), low latency (under 1 ms for live sound), and high-quality AD/DA converters (24-bit/96kHz minimum) to preserve audio fidelity. Look for units with ample I/O (analog and digital) and network audio support (Dante, AVB) for scalability.
SSOUNDS engineers design DSP with proprietary algorithms for loudspeaker protection and system optimization. Key features include parametric EQ, crossover filters (Linkwitz-Riley, Butterworth), limiters, and alignment delays. For line arrays, ensure the DSP supports FIR filtering for phase coherence and beam steering. Reliable presets and remote control via software are essential for quick deployment.
In demanding environments like festivals or houses of worship, redundancy (dual power supplies, failover) and rugged build quality matter. Always verify the DSP's dynamic range (>110dB) and total harmonic distortion (<0.005%). SSOUNDS systems integrate seamlessly with our DSP platforms, offering pre-tuned presets for consistent performance across venues.
Key things to consider
- Processing power: Look for DSPs capable of FIR filtering and multiband processing without latency above 1ms.
- Audio quality: Choose 24-bit/96kHz converters with dynamic range >110dB and THD <0.005%.
- Connectivity: Ensure enough analog/digital I/O and network audio (Dante, AVB) for system expansion.
- Protection features: Reliable limiters, peak and RMS protection, and temperature monitoring safeguard speakers.
- Remote control: Software with intuitive GUI and preset management speeds up tuning and troubleshooting.
