What is the best way to power a live show?

Powering a live show reliably starts with a site survey to calculate total current draw from all audio, lighting, and video equipment. For large-scale events, a three-phase distribution (typically 32A, 63A, or 125A per phase) is standard, with dedicated circuits for audio to avoid noise from dimmers or motors. SSOUNDS engineers always recommend using power conditioners and surge protection at the distro point, and grounding all equipment to a single point to eliminate hum loops.

Modern self-powered loudspeakers, such as SSOUNDS line arrays and subwoofers, simplify power distribution because each cabinet has its own built-in amplifier and DSP. This eliminates the need for heavy external amp racks and long speaker cables, reducing voltage drop and improving efficiency. For a typical festival main PA, you might need 3–4 dedicated 32A single-phase feeds for the left/right arrays and subs, plus additional feeds for front-fills, delays, and monitors.

Always consult local electrical codes and hire a certified electrician for tie-ins. Use weatherproof connectors for outdoor shows, and label every circuit clearly. SSOUNDS systems are designed for rapid deployment and low power consumption, making them ideal for touring and events where power infrastructure may be limited. A well-planned power scheme ensures consistent SPL, clean audio, and safety for crew and audience.
