Hey everyone!
My powerrack is a welcome tool! When it works it's awesome. However, I have experienced on a couple of occasions that there is no output - or well, no sound comes out of my cabinet. That is problem number 1 (it might relate to problem number 2). Here's the setup:
A) I plug my engl vintage 30 4x12 into the poweramp out on the kemper (I have checked that vol is up, and that the poweramp i turned on)
B) I tune the guitar and check there is signal going in - and when I strum the guitar, the output LED lights up.
C) I go to browser mode and start to play
D) Nothing happens. No sound.
I've checked all cables are good, all connections are good, there are no muted signals and volume is up. When i run into this problem, I have to turn if off and wait 5-10 minuttes - and then sometimes I will have an output sound again.
It might relate to the second problem: if I need to turn up the master volume, the setting will flick back and forth and won't stay any specifik setting. I have experienced that sometimes I can turn it up very slowly, and it seems to work better. Often, the sound will increase dramatically within a few minuttes after I set and lock a volume level (having been lower than expected on that setting). For example: I put the master vol to 5.6 - and this will be a good volume in the rehearsal room. But sometimes it just doesn't get to that level - and I turn it up to say 7.5 - without the volume actually increasing. After a few mins of playing, it'll come in full throttle though.
Does anyone have any idea what might be causing this?
NB: a third problem is that whenever I switch between rigs, it takes a full second or so before it actually changed (the prior rig "bleeds" into the newly choosen). Kinda annoying if you have to change from metal to clean in an instant...any advice?
I hope this is understandable - please let me know if I need to clarify anything.! Thanks in advance!
