Single battery as dual power supply

power

I assume that you want to use a single 12V battery to produce +12VDC and -12VDC at the same time to power an amplifier. By itself the single battery cannot make both +12V and -12V relative to local "ground" at the same time. One solution is to use the battery directly to provide eg +12VDC and us a switch mode power supply ("SMPS") to make -12VDC.
