voodoochili12 Posted March 24, 2022 Share Posted March 24, 2022 I was at a rehearsal and forgot my HX Effects DC-3 wall wart. I had my old M9's PX-2g power supply with me, and used that instead. The HX Effects turned on and seemed to be functioning normally for a few minutes, but then it started resetting every ~10 seconds when I used the expression pedal. About 10 years ago, my M9 crapped out on me because of power supply issues, and I just want to be sure I didn't do irreparable damage to my HX Effects. Thanks!

phil_m Posted March 24, 2022 Share Posted March 24, 2022 The PX-2g is 9V AC, and the HX Effects uses 9V DC. There may be a rectifier at the HX Effects’ power input jack as a safety measure, but using 9V AC could result in an undervoltage. It’s probably not damaged, but it’s generally not good to just hook up power supplies you don’t will work. Quote Link to comment Share on other sites More sharing options...

It's more likely to have a reverse polarity protection diode than a rectifier so it would have been running on low voltage so you probably got away with it. A friend did a similar thing with a Kurzweil piano and that did a lot of damage because it didn't have the protection diode, it does now!

PierM Posted March 24, 2022 Share Posted March 24, 2022 Just don't do it again. :) Quote Link to comment Share on other sites More sharing options...

Craig Good point… I do remember Frank from Line 6 saying they had that reverse polarity protection now that I think about it. Quote Link to comment Share on other sites More sharing options...

It would act as a half wave rectifier if you fed it with AC. Quote Link to comment Share on other sites More sharing options...
