Hi guys, I'm new hear.
Im in no way an electronics expert, but i do dabble swapping out faulty capacitors in power supplies, and faulty pots in amps etc.
So i have a few QSC RMS 2450 amplifiers. Only one of them has this strange issue.
When i turn it off, after a few seconds, the clip lights light up and distorted audio can be heard. After maybe 6 seconds of this, the clip lights go out and none distorted/ clear audio can be heard. I can even turn the volume pots up and down and it controls this audio as if the amp is still on, although it's not putting out the same sort of volume as when the amp is on.
This will carry on for maybe 30 seconds or so, untill the amp completely goes off and silent.
I'm guessing it's something to do with discharging of capacitors, but can anyone explain why this is happening, why this is the only one of maybe 8 of these amps I've had over the years and how i fix / solve it? Thanks
