Why is there hum or noise coming from my Vision SP-1400P?
- LLisa ParkerAug 10, 2025
Hum or noise can occur if a poor-quality cable with uneven shielding introduces noise. To resolve this, check that all input cables are shielded properly. Also, ensure all source devices are connected to the same power source. If disconnecting a laptop from power resolves the issue, then the laptop's power connection is likely the cause.
