bwata Posted August 24, 2018 Share Posted August 24, 2018 Hi everyone, When I connect my HD500X in the USB port of an IMAC, I can hear a lot of noises and hums in every speakers plugged in the Pod (monitoring, guitar amp...) Drivers seem ok, the HD works well the rest of the time. Any idea ? Quote Link to comment Share on other sites More sharing options...
codamedia Posted August 25, 2018 Share Posted August 25, 2018 Sounds like a grounding problem. Is the guitar amp plugged into the same circuit as the computer and POD? If you disconnect the amp, do the computer speakers still hum? Quote Link to comment Share on other sites More sharing options...
bwata Posted August 25, 2018 Author Share Posted August 25, 2018 Yes all the speakers hum if they are directly connected to the pod, when the pod is connected to the IMAC with USB. For example, if i connect the Pod in my soundcard by XLR cable and in the computer with USB, the speakers connected to the soudcard don't hum. Speakers or amps have to be connected directly to the pod when it's plugged with USB if i want they hum (and I don't want...) Quote Link to comment Share on other sites More sharing options...
bruce_collins Posted August 25, 2018 Share Posted August 25, 2018 Its a ground and typical issue - mine used to change output volume with laptop connected. spent 6 months fighting the hd500x and sold it - never sounded good (thin and digital) and did not impress replaced with HEADRUSH - buy used and you never need a pc except to load updates fir the firmware but everything else is easy on the tablet interface Quote Link to comment Share on other sites More sharing options...
