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 that matches the power requirements of your audio gear, including dedicated circuits for subwoofers and line arrays, and using quality power conditioners and generators when needed.
Powering a live show reliably starts with calculating the total current draw of all equipment—loudspeakers, amplifiers, lighting, and backline. For professional audio, SSOUNDS recommends using a three-phase power distribution system with separate circuits for audio to avoid noise from lighting dimmers or motors. Always consult a qualified electrician to ensure your setup meets local codes and provides adequate headroom (typically 20–30% above peak draw).
For outdoor or remote events, use a silenced generator with automatic voltage regulation (AVR) and a clean sine wave output. SSOUNDS amplifiers feature intelligent power management and PFC (power factor correction) to handle voltage fluctuations, but a stable supply is critical. Use heavy-gauge, balanced power cables (e.g., 32A or 63A CEE connectors) and distribute power via distro boxes with individual breakers per circuit.
Best practices include powering up amplifiers last and powering them down first, using a sequenced power-on system to avoid inrush current spikes. SSOUNDS DSP presets include voltage monitoring to alert operators to issues. For large-scale shows, a dedicated power technician should monitor load and voltage throughout the event.
Key things to consider
- Calculate total current draw and add 20–30% headroom for safety.
- Use three-phase distribution with separate circuits for audio and lighting.
- Employ silenced generators with AVR and clean sine wave output for outdoor shows.
- Use heavy-gauge, balanced power cables and distro boxes with individual breakers.
- Power amplifiers last and power them down first; use sequenced power-on systems.
