I have two 6100 powerheads. So far no problem.
Today I started controlling them ( I have a Profilux aquarium controller)
to make sinus waves.
Now, with every sinus waves the motor controllers hum in the same frequency. Is that normal? Can I do something about that?
The controllvoltage is 1 - 8V

Thanks for any help

No one had similar experience? With single/multicontroller from Tunze or Neptune Sys or any other controller?
