Hi all...
I have built a vacuum tube vari-mu comp and to control the amount of signal through the side chain I use a 6pos/ 2pol switch with resistors. This is to get as accurate balance as possible. Everything is working perfect and the comp has very fine values and sounds very good.
But... I wonder how to proceed to set specific threshold values. It is not extremely important but it would be nice to know how to measure or calculate these values.
I do not have a complete schematic to post at the moment because I have it on another laptop and it has been changed quite a lot and is therefore not "updated" But I guess that the question could be answered in a more common way.
The comp has a gain of 26dB but since it has to handle signals from a previous preamp I guess that the signal from the preamp sets the threshold. I guess (again) that I could use a preamp measure the output signal of... lets say 50dB and then connect the comp and elaborate with a pair of resistors until the comp show gain reduction and so on? It will take som serious time to do it of course
Sorry for a maybe stupid question.
Best regards
/John
