PA System Setup Part 2
Wiring the system
- Don’t run all amplifiers / equipment off multi blocks. Be aware of total power drain (all electronics must state power consumption). A 230V, 13A wall socket provides around 3000W. This is enough for around 1500W of amplifiers. If more power is needed, use different mains circuits or ideally a higher current supply (many venues have 32A supplies, but these require special connectors also). Overloading a mains socket is potentially dangerous, and likely to cause a power out during use.
- Ensure all connections are the correct kind of cable
- Ensure all connections are between correct points (sources to mixer inputs, mixer line outs to amp inputs, amp outputs to speakers.
- Keep lighting cables away from ALL sound including mains, use separate circuit if possible.
- Run all cables neatly, use cable ties to tidy excess cable length.
- Tie up excess cables in figure ‘8’ shapes, not circles to avoid induction loops and noise pickup.
