Output Distortion

philamelian · Post by **philamelian** » Mon Feb 13, 2012 10:36 am

I am experiencing a distortion when volume is at top level in Kronos 88 but there is still some distorted sounds when its at lower levels but not that much. This is quite handy for me to use the volume knob this way, in performance especially. Distortion is especially appearent in piano sounds and while playing in forte. I read there are some issues about piano samples. But only few people were mentioning about this. I have checked this with headphones pluged directly to Kronos and in different venues and in my studio all the same. Patches are not peaking as well, checked it. Quite annoying problem and effects my comfort of playing. I don't have any problem with my Roland fantom keyboard under same circumstances.

It is a very stupid issue with this 3000 pound device, I would consider such a device faulty. Is there anyone has a solution for this or who knows the what cause this?

Hmm, how come all dissapointed first time posters have to refer to other gear by other manufacturers to "prove" their point?..

What's the name of that being in Scandinavian mythology?

In another topic, someone mentioned that the Set List EQ may be causing the distortion. I don't know if that's the case or not, but do check out page 671 of the Kronos Parameter Guide for how it all works.

Do you experience this problem also with preload Programs or Combis?

Yes I have this with factory programs as well.

Fair enough Phil, sorry for being a bit harsh.

You caught me on a bad day!

In my opinion you have to contact your Korg provider for service. Did you installed an additional RAM memory? Maybe this can be a problem. I don't know but isn't something normal to have distortion using headphones with the factory programs.

Good luck to find a solution.

Thanks andreidelait, that is in the plan. Unfortunately I will need to wait for it for a month at least as I am on tour now. Unfortunately we will be shooting DVD in one of the dates. This will cause a lot of headache to me....

Do you experience the same phenomenon if you use the optical output? What if you record your performance to a WAV file (by pressing the sampling record button whilst playing) and then playing the resulting WAV file back on another device?

OK, one more thing to check then before calling Korg's service dept. Check the "Internal Headroom" parameter in Global Mode - Basic. (pg 756 of the parameter guide.)

Internal headroom is at 48. It should be ok I think. I have also updated to the OS 1.5 with a possible hope to solve it but didn't work.

If you read the manual, it will tell you that you are most susceptible to distortion with the 48 dB setting. You should lower it to prevent distortion.

I have checked the online manual several times, maybe I keep overlooking but couldn't find what you mentioned. Can you please send me the the page number and link of the manual you are looking.

I remember I checked with the standard headroom setting before but recheck it again though. If this is the issue still it's a bit weird because this device comes with +48db as default.

This answer was posted over a week ago. The section on Internal Headroom is in the Parameter Guide, not the Operator's Manual. It starts on the bottom right corner of page 756 and continues on page 757. Reduce the setting to a lower value to increase the D/A overload margin.
