Hi, I've solved his problem by cutting out some eva foam. Because I use the amplifier less than a meter away, I think sound is good for me.

-Does it matter wether an instrument is connected or not to the SonicBar? -if I connect an instrument the noise is always present Does connecting the headphone jack kill the signal to speakers? -Yes, if I connect the headphones to the headphone jack, the sound is only heard through the headphones. Does the noise appear in the headphones at healthy listening levels or when cranking the headphone amp? -If I connect the headphones, the hiss noise is heard. I do not know if it's healthy or not, but I do not like it, so what I do is connect the headphones to the rear mixing outlet and then I do not hear the hiss sound. When I need it. Are you using a quality pair of headphones capable of reproducing 20htz to 20khtz? -my headphones are the model Sennheiser hd515, with frequency response 14-26,000 hz In short, the sat of korg says that it is normal so I will try a trick to hide the hiss with rubber eva. Later I will post results and photos...

This is my sonicbar but if you are less than a meter away you can hear the noise. Korg's technical service tells me it's normal sound. With headphones is a horrible noise. [video:youtube]https://youtu.be/uXA5nBJGUg4 It has been difficult to dismantle. Here some photos.
