I have a velodyne F-1500 sub and lately it screams a high pitch note everytime I turn it on. At first it was only occasionally but now it is constant. I unplugged the input jack from my receiver and it still does it. If anyone has any idea what the problem could be I would really appreciate it. TIA
Hate to say it, but it sounds like you're going to need to have your dealer or Velodyne fix it. Sounds like a problem with the amp. I doubt that it is user repairable.
