Hum is usually a grounding or cable problem. Check cables and power first, then isolate the source. A message nobody hears is a message you never sent. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Unplug sources one by one to find the cause. - Use balanced cables on long runs. - Plug audio gear into the same power strip. Quick answer 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.

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. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
