Powered Mixer issue

[kia_forte]

I have one of those inexpensive Rockville Powered Mixers that I use with my trio at smaller gigs.

Noticed an issue when plugging a cord into the line out and into a powered monitor - that sometimes cuts out the mains.
Unplugging it and powering on/off usually resolves the issue.
It's an annoying quirk - Anyone else ever have an issue like this?

Line out from what and plugged into where on the mixer?

Maybe there is a big signal spike and the mixer is going into protect mode?????

I'm going to be the guy to say it....being Rockville and inexpensive you may have gotten what you paid for.

Simple line out from the mixer line out jack to input on a powered mixer silences the mains. Intermittent issue. Very strange?
What I paid was $137 about 5 years ago and this mixer has at least 200 gigs under its belt. It has been stellar. I bought two of them.
I'm retiring it soon but this problem is just a mystery to me?..

If your plugging into an XLR jack is the phantom power turned on in the powered mixer?

If resetting (unplugging, on/off) consistently fixes the issue, then usually its an electronics/internal problem rather than a wiring (xlr/1/4 cable issue) problem... so a board on the mixer might be going.
