I use 12V battery + 240V/220V (Pure sine wave) inverter to run sound gear. I have tried connecting 12V to 9V DC/DC converter for my 9V pedals (instead of using DC power adapter - the object being reduce my heavy load with one less transformer) straight to the same battery as inverter is connected to and I get hiss/noise. Any suggestions to eliminate this noise? Is there an electronic component I can add that will address this problem?
P.S. No I dont want to use another battery (more weight) and using the small 9V batteries is an added cost I dont want. I would be happy if I could use a DC to DC converter as I outlined above. Its light and one time cost.
