AN920 Posted May 16, 2007 Report Share Posted May 16, 2007 Employ a current limit circuit and power your voice circuit before the current limiter. Quote Link to comment Share on other sites More sharing options...
audioguru Posted May 16, 2007 Report Share Posted May 16, 2007 Please provide more detail, maybe on an attached schematic.What is a "dual power supply"? Is it a positive supply and a negative supply? Shorting one does not affect the other. Quote Link to comment Share on other sites More sharing options...
LostViking Posted May 23, 2007 Report Share Posted May 23, 2007 Treat the two supplies and the two circuits as such. Don't connect between them and they can't affect each other. Quote Link to comment Share on other sites More sharing options...
