Hi folks!
Wonna open one more CL-oneB opto compressor thread.
Who used this device know how good it is.
Original schematic can be found in tech docs page.
Main audio path looks pretty typical:
input transformer > threshold/ratio/gain pots > gain reduction element (aka GRE) > tube output amp (pretty typical for all tubetech gear)
The most interesting part of all compressors is a side-chain/detector schematic.
I redraw this schematic in a more visual and understandable way. Check it out.
In the future I'm planning to emulate it in LTspice.
The most "magic" element is a GRE which is a complex opto element (black box in the real device).
as I read in the previous threads:
GRE contain LED/LDR combination and "gain-change-linealizing" circuitry.
Any ideas how to test/create/emulate a such GRE for getting correct compression curve from a such side-chain/detector schematic?)
