Yesterday I had an unexpected unpleasant problem
while I was creating a patch directly on my HD500 suddenly developed a distorted noise (a sort of wild feedback) that in a matter of seconds has gradually risen exponentially in volume to impressive levels, unfortunately I was using headphones and it was quite unpleasant and painful..
the first thing that came to my mind was to take off the headphones and turn down the master volume of the HD500, but the volume had no effect at all, so while the headphones were continuing to fry I finally disconnected them, and I believe I saved them, at least I hope so, I don't know if they have suffered some damages, but at least it seems they still work ..
when this happened, the HD500 was connected to the PC, I was not using the HD500 Edit application, in practice the POD was working also as a PC audio interface, to eventually listen to audio tracks using the headphone output of the POD ..
in that unlucky moment, I was moving a delay in the chain to hear where I liked the most, and suddenly happened the shock, the headphones seemed gone mad ..
later, I moved the effect again, timorously I tried to reconnect the headphones and I could not hear anything, neither noise nor sound, and I thought: s.h.i.t! .. I burned my headphones or my POD!...
.. but hopeful I tried to select the next stored patch, and then returned to the previous one, and everything was normal and running again..
it was an unpleasant experience, it might be handy to know what was the cause
anyway if it were to happen to you, remember!!.. the first thing to do is: unplug the headphones!!..
if I remember correctly, I think I read about a similar problem in the past in this forum, but I don't know if it was solved
