What is the right power frequency for events, 50Hz or 60Hz?
Quick answer
The right power frequency for events depends on your location: 50Hz is standard in most of the world (Europe, Africa, Asia), while 60Hz is used in North America and parts of South America and Asia. Always match your PA system's power supply to the local mains frequency to ensure safe and reliable operation.
For professional audio events, the power frequency is determined by the local electrical grid, not by the equipment choice. Most countries operate on either 50Hz or 60Hz mains, and SSOUNDS loudspeakers and amplifiers are designed to work with both frequencies (typically 50/60Hz auto-sensing) within their specified voltage range. However, you must verify that your specific equipment is rated for the local frequency, as some older or specialized gear may be frequency-sensitive.
Using the wrong frequency can cause transformers to overheat, motors to run at incorrect speeds, and electronics to malfunction. For touring productions, SSOUNDS recommends carrying a power distribution system that can handle both frequencies, or using a frequency converter if operating outside your home region. Always check the label on your amplifiers and DSP units for their rated frequency range.
In Africa, where SSOUNDS has a strong presence, the standard is 50Hz (e.g., Nigeria, Ghana, South Africa). If you're importing equipment from a 60Hz region, ensure it's switchable or use a step-down transformer that also converts frequency if necessary. For most modern SSOUNDS systems, the power supply is universal and will work on either frequency, but it's always best to confirm with the manufacturer's specifications.
Key things to consider
- 50Hz is standard in Europe, Africa, Asia, and Australia; 60Hz is standard in the Americas and parts of Asia.
- Most modern professional PA equipment, including SSOUNDS systems, is designed to work on both 50Hz and 60Hz (check the label).
- Using the wrong frequency can damage transformers and cause equipment failure.
- For international touring, use a power distribution system that accommodates both frequencies or a frequency converter.
- Always verify your equipment's rated voltage and frequency before connecting to a local power source.
