Modulating channel without being connected.

A few days ago my Soundcraft ui24r started modulating channels 17, 23 and 24 without having any device connected to the respective inputs. And when you increase the volume there is a very loud noise. The signal indicators are there showing as if there is a signal coming.

    This sounds like a hardware issue. I would suggest contacing tech support for your country. If you're in the USA you can call 844 776 4899. You might also check about in on the Soundcraft Ui24R Facebook Group.

  • I´m having the same problems! The channel 17, without any devices connected to any input, have a very loud noise and the indicators shows as if there is a signal coming.
