Beyerdynamic DT 990 equalization circuit - need help

post #1 of 7
Thread Starter 
Hi;
I just build a equalization circuit for my old Beyerdynamic DT 990 after reading the http://headwize.com/projects/beyer_prj.htm

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

fixed. by the way budgie, did you notice you have 666 posts?

He probably won't answer, because he wants to preserve his 666 status for as long as possible...either that or he's dead...

Is this thread dead yet?

Capt Z- change the value of the resistor to ground - a higher value will reduce the amount of highs the circuit removes. Try removing the 22 ohm resistor and see if that gets you going in the right direction.
