We are having a grounding issue with our SX20. Currently we are using a ground lift plug and that is working at the moment. This issue is a buzz/humming nice. We have swapped every piece of equipment out and still have the issue. Ground in the confrence room itself has been checked.
The only thing i can think of is a compatablity issue.
The system was orginally a C60 Dual Profile 52
We swapped out the C60 and installed the SX20.
For about a month everything was fine then we started to hear this noise. Again when we use the ground block we no long hear the noise.
Do you find any difference when not connecting the presentaion cable to a pc or laptop with audio connected.
Are you taking out the audio via Dnam or external speakers.
Most common reason for the humming buzz is speaker wire. Make sure no on changed the input and output ports for audio at the back of the codec. Have u connected two monitors on both the hdmi out or just one.
