Last week my Kabinet was working fine. Whenever I check on the poweramp on Output page 9, I would here a click inside the profiler and a light audible pop from the kabinet -- which I knew it was on. Today I checked on the poweramp and I heard the click inside the profiler but no "light pop" from the Kabinet and thus no guitar sound. Guitar sound is working fine outputing to my studio monitors from interface. I tried messing around with my volume levels and it seems that now I can get the Kabinet to give a light pop again when the poweramp is on, but this light pop is much quieter than normal. I also hear a hiss from the Kabinet with poweramp engaged but no guitar sound. Hiss is gone with poweramp off. So, I assume the speaker cable is fine.
Last week I was messing with rig and master volume levels and global EQ settings with the poweramp off. Could I have checked or unchecked something incorrectly?
