Welcome back, Omrat! I hope you had a great vacation.
After the tests you did, we know that your power amp is behaving as it should (just as it did before). Thta means there is a problem with the wiring: either the cables or inside the cabinet.
I know you've tested your cables, so I don't think that is a likely problem. It's possible, though, that the problem is intermittent — sometimes a good connection, sometimes not. Maybe a plug that is almost, but not completely, inserted into the jack.
Is it possible that one of your speaker cables is still reversed? Have you tested that the red banana plug goes to the tip of the 1/4" cable for both connectors?
If the cables are correct, we are left with either the jacks in your cabinet or the wiring in your cabinet. If you have your ohmmeter available, I can walk you through a test to see whether the jacks are working properly and whether there are wiring problems. Whatever the problem is, it is probably a simple one, and when we find it, we will both wonder why we didn't find it sooner.
In this case, patch cord = two-conductor shielded audio cable with a 1/4" plug on each end. Guitar cables will work fine.
Cool. Here are some tests to do.
- Plug one end of one of your patch cords into the mono jack on your cab (leave the stereo jack empty). Measure the resistance from tip to sleeve on the free end of the patch cord.
- Unplug the first patch cord, then plug it into the stereo jack on your cab. Measure the resistance from tip to sleeve on the free end of the patch cord.
- Now leave the patch cord in place, and plug a second patch cord into the mono jack of your cab. Measure the resistance of each of the two cables from tip to sleeve.
Aiii! This is all normal. Everywhere we look, there is nothing to explain the problem of losing one channel when both are plugged into your cab. And yet the problem is there (true?).Results:
1. resistance ~4,4 Ohm
2. resistance ~8,1 Ohm
3. mono ~8,1 Ohm; stereo ~8,2 Ohm

Tarmo

Have you verified that this problem exists with all patches?
It's good to know your name. "Tarmo" I understand. It's a good Estonian name. "Omrat" doesn't sound so Estonian.
Just use a mono preset. If you don't have one, you can build one by using an amp sim and a cab sim. You should get sound from both speakers if both channels are hooked up.Ok, now I'm strating to believe that maybe it is Axe FX ( preset or I/O settings ). Do You have some random stereo preset, that You can share ? If the problem still exist, I will do more tests with ohmmeter.

I just realized that when I said to use a shielded audio cable, I was confused. The cables you used for the test were fine, but shielding was not necessary. Your speaker cables would have worked just as well. Sorry... I think I was asleep.
