I realize that there are a number of threads involving new Kemper users' experiences of "fizz" with high-gain tones -- however, I felt my situation was unique enough that it did merit its own thread. Apologies if this is redundant (although I did use the search function here).
My issue is this: through headphones, with the headphone "space" parameter set fairly high, everything sounds *amazing.* Guitars have no right to sound this good over headphones! However, I have a single studio monitor (new KRK Rokit 6", G3) which I connect directly to the Kemper like this:
Kemper main output jack -> 1/4" TS -> XLR input of the monitor (i.e., connected via a single TS->XLR cable).
Through both the headphones and the monitor, clean profiles sound amazing.
But this isn't the case for the monitor with distorted/high-gain profiles; for whatever reason, things sound a bit digital and fizzy, sort of the way the Line 6 POD HD sounds. I'm sure there's no problem with this specific KPA unit as the headphones sound fabulous. Nothing sounds damaged or alarmingly bad, but the monitor doesn't sound nearly as good as the headphones, and it seems that the opposite should be the case!
Another thing to note: I don't turn the monitor up very loud at all, as I'm in a small-ish apartment (by necessity). Again this is a *single* studio monitor -- perhaps this is some problem that could be remedied by buying a second monitor, or switching to smaller monitors that I could get away with cranking louder?
One final possibility to note is that the LED above the "MASTER" button does turn red often while playing.
My guitar pickups are fairly high-output (DiMarzio Crunchlab/Liquifire combo).
Cheers, and thanks for your patience! This is an excellent forum!
