The radical new design of the 2166 compressor proved to be too difficult to get to work 100%, even though I have tried numerous mods to make it succeed. It should work (according to the datasheet) and it does work most of the time. However, some extreme settings of the controls would send it into weird oscillations. Therefore, I’m scrapping this design and will make a pcb run of the more conventional Q&D version that has long been on the web site (though updated slightly).
(Edit: This version was never released for sale.)
Cool. I have3 one or two of the old chips packed away somewhere. A RTS board might be just the thing to get me moving. As always, my request would be for a separable sidechain input, if feasible. (So I can put a compressor somewhere in the signal chain other than first without noise issues.)
[…] At last! After a pcb layout error, and then the maker of the prototype pcbs dropping the ball on the revised boards, I have finally […]
Just a quick note:
This was a test prototype of one of the revised designs and was never made into pc boards for sale, nor was the schematic ever released.
