Video interference with sound?

[DusX]

Any chance it's the bass vibrating the projector.

Hi DusX

No is the short answer I guess, the image is stationary (the edging of the image stays still). 

You can tell it's internal and within the cables which is the first thing I will change when I go in tonight, starting with my video cable.

Thanks for your reply :)

It seems some ground problem. Try to pur a couple of d.i.boxes in audio chain, between PC and mixer or between mixer and loudspeakers .

Thanks Maximortal

That sounds like good advice and worth trying.

Cheers

are you in a theatre with an induction loop for the hard of hearing? i once discovered a Sennheiser system was interfering with the projector, but only with certain sounds.

Hi dbini

No, we don't have an ILoop,.... 

and no radio mics in use.

Thanks

@goodboy,

Yeah, outside of something really bizarre, ground loop would be the first thing to check.

Best Wishes,

Thanks for all the help,

I will try the di box fix tonight.

Thanks Maximortal

That worked! (di's between sound mixer and speakers)

Thank you all
