Trying to debug an issue. Not implying there is something wrong with the Kemper yet. Just asking for debugging help.
I have a 1/4" TS cable plugged from my Kemper Monitor Out to my QSC K10 input. I think that's the right cable, but the output does not have a label of TRS vs TS on it so who knows. Manually says "TRS unbalanced" which I've not heard of.
The last couple of practices, about 45-60mins into the practice, I've had crackling and fading output on the Monitor output. It actually sounds like a fading tube going bad or something or like I'm clipping the shit out of the K10 - which I'm not because the volume is really low and drops. Does Kemper actually profile a breaking tube amp?
Initially I suspected my cable. Practice ended and went about my way.
Last practice, same thing happened about an hour into it. This time, I played my keyboard through the other K10 channel - sounded perfect. That took the issue down to the Kemper, the cable, the input on the K10. The K10's speaker was fine.
I swapped cables and the output was still low. Weird. Takes it down to Kemper and K10.
Then I maxed out the Master Output knob on the front of the Kemper taking it from 8.5 to 10.0. BAM! The sound came back to normal.
Freaks me out that I could fix the problem by tweaking a knob on the Kemper. Fixing it like that rules out a cable problem doesn't it?
Anyone else had any Monitor Output fading issues or crackles?
