A steady low hum usually comes from a ground loop (equipment plugged into different power points), a poor or unbalanced cable, or mains interference from lighting dimmers and chargers. Work through it in order: unplug sources one by one to find the culprit, use balanced cables over long runs, plug all audio gear into the same power strip, and keep audio cables away from power cables.
Key takeaways
- Unplug sources one by one to find the cause.
- Use balanced cables on long runs.

05Frequently asked questions
Is the hum dangerous?
Hum itself is not, but a tingle or shock from equipment is a safety issue: stop and have the wiring and earthing checked.
Why does it hum only when the phone is charging?
Cheap chargers add noise. Use the original charger or unplug while playing.
Can long speaker cables cause hum?
Speaker cables rarely do; long unbalanced signal cables are more often the cause.
When should I call a technician?
If the hum remains after you have isolated each device, or if there is any shock.
