I have enttec usb open.
But I found this generates DMX-signal noise such that 10ch or 11ch varies when 9ch is adjusted.
Please recommend dmx interface without noise...

Well you have one. The devive it's self will not create 'noise' on the dmx line unless it is faulty.
Please check all the connecting cables from the device to the fixtures.
Also could actually be you computer thats is causing the problem. I have seen laptops with poor sound cards putting out audiable noise when connected to a large PA so perhaps the same is possible here ?
Enttec Open device is good. Pro is better.

Hmmm. I found it with DMX tester that is lite-puter cx-1c.
CX-1C displayed the noise clearly.
Daslight didn't generate the noise.

Take a look at the DMXking ultraDMX range, we don't make anything that doesn't have an onboard microprocessor since there are so many potential problems with designs like the enttec open.
For the same price as the enttec open you can get the ultraDMX Micro which is actually 100% compatible with the enttec pro protocol.
