We have already installed 3 powerpacks to control some "tivoli" flexiline lights working at 220v. Total installation is 70A by phase.

When the dimmers are executing the light program we have video interferences at our proyectors.

But when we put all the light channels to the top, the interfarence seems to disapear.

As the dimmer curve can be set to On-Off at the menu of the digital dimmer pack, I wonder if we will fix it as some people says that interference is greater at the middle value of the dimmer (50%)

I remmember I had a similar problem with a proyector in another location when we used all our blinder light at time very quickly and we "fix it" by disconnecting the ground wire at the proyector power plug.

I dont like to do this even if the proyector can not be touched by the audience as it is fixed at the roof.

Any help will be welcome

Thanks.
