Members pgtcobra Posted January 12, 2011 Members Share Posted January 12, 2011 Hello! anyone have a new ADJ quad phase?? I have a problem with my light ... high-pitched sound that surely comes the power supply .. ADJ say this a engine sound but i have a ADJ Tri-phase and ADJ Quad Phase, which, however, uses the same engine I am not even able to run the QUAD PHASE at low volume in a small room without being told from where is the high-pitched continuous sound. The engine noise is the same as the tri-phase But the high-pitched noise of the power is really disturbing ... anyone have a same problem?? ThankDavidSorry for my english...

Members drummer762 Posted January 12, 2011 Members Share Posted January 12, 2011 Sounds like your unit might be defective. I would suggest bringing it to the dealer where you bought it and see if they have another. Plug theirs in and see if it makes the same sound.
