Hello People!
I am in the process of knocking together a 8 into 2 line mixer as seen in this article, and the +24 volt power supply has been causing a few headaches. If I want to put in things like headphone outputs and other gimmicks later, every other circuit I have runs on bipolar +/-15 volts or thereabouts.
The schematic for the JFP gain module can also be seen at the same LINK, upper centre of the page.
What would happen if I hooked up a JFP module to +12v instead of +24v and -12v instead of ground? I know some smart alec is going to say 'Just wire it up and try it!' but I would like to know if there is are theoretical grounds for possible problems. The main thing I can think of is that (and my understanding of JFets is very basic) perhaps the Gate would not like being at 12 volts higher that in the unipolar power supply scenario. Perhaps a capacitor in front of the gate would block DC voltage and prevent this problem.
Advice would be greatly appreciated. I think a Bipolar PSU powered JFet gain module would very useful to have!
Thankyou in advance!
