Me again.
Try this, boost 5K high shelf to +15 db and then check the
difference between the roll off control on 6 and then on 24.
The high end will turn to something like 1.2K boost.
please be patient, I used the eq for about 2 months and
never noticed it was not working properly!
thank you for your help.

P.D. I have the latest Vegas realease available today.
