OK-I feel like a real knucklehead, as I have been reading through the various threads on attenuators and have not seen the light....
I am replacing some Bourne 10k linear pots installed into a pair of eq boards with 24 step Elma switches....and I need to find a calculator to determine resisitors values for the zero position, boost and cut. I only want ~6 db in either direction, so .5 db or 1db steps are what I'm after.
Would anyone be so kind as to help out and point me in the right direction? There must be a thread on this already...
for the curious the boards were apparently made by 'T de P' for someones [defunct] custom mixer project, and I got them on Evilbay.....after tracing them out, they are exactly the same as the control section of his 825 (schemo on Gyraf site), minus the low and high shelves. I intend to implement similar to this: http://forsselltech.com/schematics/EQ1A.PDF
Shame the elmas won't fit in the direct mount scenario..
