Hey all,
I've been needing to tame 4 channels of vox for a small PA rig that I use with my brothers band and this seemed interesting.- http://silonex.com/audiohm/compressor.html - see fig. 4 I already have a dozen of their NSL-32SR3 optocouplers on hand for use in my guitar amps. This little comp should fit the bill.
I added the current mirror from fig. 6 and a full wave rectifier that feeds the Attack/Release RC network. RV1 will be panel mounted and labeled "Squeeze". RV2 and RV3 will be trim pots which will be adjusted during testing, although they could be brought to the front panel also. I couldn't find any info on subs for the 2SC3068 but it doesn't appear to be anything special so I'll be using BC550Cs since I have a large stock of them. Any ideas or suggestions would be much appreciated.
thanks,
James
