This building used to be really noisy with the old magnetic ballasts.   Getting hum out of the mic in one studio was fruitless.   And even heard buzzing in a hallway phone handset that got loud when you walk under one hallway light fixture.

Just to be aware, the ballasts may be driving the T8’s with a supersonic frequency that might cause interference.

We have several T12 fluorescents wired to old external magnetic ballasts mounted in another room electric box to minimize studio hum.

 

Is it OK to replace these with T8 wired to new external electronic ballasts mounted in the same place?
