Hi, I have a (probably) dumb question about profiling.
I've had my KPA for a couple of years now, used it for gigs and rehearsal many times, but I never had the time to do a proper profile of my rig.
Today I finally got the chance to spend some time in the studio with a friend - the owner of such studio - who was very curious to see the kemper in action and the profiling process, so I loaded all my rig in the car and went there.
We set up the rig properly, mic'd the cab with thee microphones (my own Sennheiser e906, a shure sm 57 and a ribbon microphone), everything went into a Thermionic Culture Fat Bustard (a valve mixer) and back into the Kemper.
Since I was in the studio I spared no volume and pushed my amp where I set it for big gigs. It's a Reeves Super '78 50 watt head, not exactly a bedroom amp, I put the master at 50%, which is quite loud indeed.
The "problem" was that we could only keep the "return level" parameter on the Kemper almost all the way down, at -32 db. Ideal level ended up being -31,6 db. I tried entering both with the xlr cable and with the 1/4 inch input, and the result was the same.
I'm pretty confident I wasn't overloading the signal via the Fat Bustard: going into the mixer the sound was absolutely right.
So I want to ask: is there some other setting I should have tweaked before? Something in the input section? Or is it the normal behaviour of the KPA?
The profile ended up sounding good anyway but it wasn't exactly the tone we had mixed before connecting the kemper and I think dropping the return level so much might have had something to do with it.
