  • Hi Terry,

    Thanks for posting. 

    Can you please provide me with some more information about your setup? If you're using your speakers with other devices, please tell me how these are all configured. If your speakers are connected to a surge protector, please make sure that the surge protector isn't being overloaded. If things like lights are connected to that same surge protector, this could introduce noise into the signal and should be connected separately. 

    Check out this helpful guide below that will walk you through how to properly gain stage your setup - Gain Staging 101 - How to get a clean loud signal

    I hope this helps! Let me know if you have any additional questions.

    I have 2 x Alto Black speakers, a pioneer ddj-sb2 controller and a new Dell laptop using Serato. The hum only exist when either I connect both speakers to controller via xlr to phono leads or if I connect both speakers together via a dmx cable. It basically only happen when both speakers are linked in anyway. On there one there is no hum.

    Thanks

    Terry
