Title: Help? SWA1801 sub quit after 4 seconds
Post by: Loren Richards on July 11, 2016, 02:59:46 PM
I moved and hadn't turned on my Mackie SWA1801 sub in about 3 years.   As soon as I powered it on, the LED lights lit up and then there were some slight popping or weird static-y sounds for about 4 seconds and then the lights went off and you could tell it was no longer powered.   I've unplugged it and plugged it back in and it won't show any signs of life.  I took off the back panel and checked the 3 fuses that I can see and they were all good.   Any tips on getting this baby back to work?

Power supply failure.  It needs the sound doctor.

Did you check the fuses or just look at them?  Blown fuses are not always visble to the naked eye.

I seem to remember that it is a known issue that they die after a while, possibly an amp failure.
