Hi;
I just build a equalization circuit for my old Beyerdynamic DT 990 after reading the http://headwize.com/projects/beyer_prj.ht...

The reason I built this curcuit was to tame the exessive highs in my DT 990. However, the Equalization Circuit - Version 1 did tame the high frequencies to much.

I would like to build a similar circuit with only 30 - 60 % of the attenution.

Can anyone advise me, what values of the Equalization Circuit needs to be changed to achieve less attenution?

Thanks
