What is the best way to power a live show?
Quick answer
The best way to power a live show is with a properly designed, high-current electrical distribution system matched to your PA's power requirements, using dedicated circuits, quality cabling, and professional-grade amplifiers with built-in power conditioning.
Powering a live show reliably starts with understanding your system's total power draw. Calculate the combined current demand of all amplifiers, consoles, and backline gear, then ensure your distro provides sufficient amperage per phase. SSOUNDS engineers recommend using a dedicated power distribution unit (PDU) with overcurrent protection and voltage monitoring to safeguard equipment.
Amplifier choice is critical. Modern, efficient amplifiers like SSOUNDS' own designs deliver high output with low current draw, reducing strain on generators or venue power. Always use balanced, shielded power cables and avoid daisy-chaining multiple devices on a single circuit. For outdoor or touring shows, a generator with automatic voltage regulation (AVR) and sufficient headroom is essential.
Grounding and safety cannot be overlooked. Use a star-ground scheme to prevent hum and ensure all equipment is properly earthed. SSOUNDS systems include robust power supplies that tolerate voltage fluctuations, but a professional power conditioner or UPS for sensitive digital gear adds an extra layer of protection. Finally, test all connections with a multimeter before show time.
Key things to consider
- Calculate total current draw and use a distro with adequate amperage per phase.
- Choose efficient, high-quality amplifiers to minimize power consumption and heat.
- Use dedicated circuits and avoid overloading single outlets or extension cords.
- Implement proper grounding to eliminate hum and protect equipment.
- For outdoor shows, use a generator with AVR and sufficient capacity for peaks.
