Profiling problem, need help!

Painfulpenetration · Feb 10th 2012

Hi folks,

I've a poor english lvl, i hope you'll understand me...
I don't know if it's a real problem, or if it's just me, but when i want to profile a amp, i don't have any sound in my monitor.
First i switch to the Profiler section, then i go to the Reference amp. Here i should ear something ( the kemper is correctly wired and have the last firmware version) but nothing... My amp isn't very loud ( voice lvl, i live in an appartment, but even with the return knob to +32db i don't ear anythng and the kemper can't make a profile.
Should i crank my amp very loud, use an external preamp to boost the mic signal? or my kemper have a problem?

Thx, and congratz if you've understand me!
Simon.

Are you using a condensator mic?

Painfulpenetration · Feb 10th 2012

I have a SM57

Try a different mic cable. You'd be surprised how often the cable is the problem - whether USB, midi, 1/4 in or XLR.

+1, check your cable

Painfulpenetration · Feb 10th 2012

Done, but nothing change, when i put the return knob to +32db i ear a thing, but it's very low and my SM57 is in good condition

Have you tried holding down the system key for the duration of startup when you switch-on the KPA, as I was told by Kemper support that doing this resets something, quite what I've no idea

Correct, it resets the System cache. Was a fix after the update, no need to do it every time, just the first time after update.

Not quite as simple as that. I just updated mine and did the system key startup thing, but mine will not profile now

guitarnet70 · Feb 11th 2012

Let me quick check it....10 min to setup things .....the rig you're on doesn't have a loop, right?

oops, correction, it is working, I didn't have the amp volume up high enough

Go to the support page of the main Kemper site and click on "older operating system versions"

Everybody else is working, how is exactly your signal chain?
