Kemper Amp Hiss

jpattjpatt · May 16th 2023

Hello, I recently acquired a used kemper powered rack. I have been trying to diagnose if the amp hiss I am experience is normal or excessive?

Here is the link to the audio file: Amp Hiss

0 Noise Gates , 0 gain, Mesa Lonestar Clean Channel 1 profile. My Clean Tone.

First play through is single coils, second is noiseless. The noise you hear in the second play through occurs even when nothing is plugged into the input of the amp.

What cabinet type did you record from?

Any amplified speaker at loud levels is going to have some hissing noise. I played your track at around 76db and did not hear the hiss until I raised the volume to 86db at 2 feet away. I think it sounds normal.

BayouTexan Thanks for giving it a listen, Im using a York Creamback IR. Just sounds a bit more noisy than my actual mesa boogie, but I guess I can do some more Eqing.

Did you record with your phone? Or the signal directly in the digital domain?

What I meant was what "physical cabinet" you used? The Kemper Kabinet is not meant to be mic'd or recorded. When recording directly from the profiler into DAW you will be able to omit any hiss.
