audioforge said:I ve just finished a Gssl with a "clintrubber" 12 positions filter.
(simple hi pass filters + api 2500 filter)
as calibration of the 2 trimpots for loud and medium position were not described (except for threshold variation)and they are frequency dependant here a simple way to have them working "properly" as in the "original" api design.
First: threshold max(+15) output 0.
compressor ON
Simple hight pass filter (stephen/greg).
as designed it couldn t be adjust as unity gain.
so if you want unity gain change 10K trimpot for higher value or the 1K resistor to a 2K or 2K7.
apply a 0db signal 1Kz measured at the L R greg pcb inputs.
adjust the trim so you have 0db at the filter pcb output.
hope it can help
