Asymetric Pre-amp Scheme for Single or Dual Power Supply

Asymetric pre amp scheme for single or dual power

Concatenation of the two previous schemes Asymmetric Pre amp and Asymetric pre amp with dual supply voltage.

Power supply
As already stated, a single or dual power supply is required to power this circuit. You can do with a single +15 V power supply as described on page single supply, or a dual power supply as described on page Asymetric pre amp with dual supply voltage.

But any other single power supply delivers a regulated DC voltage value between 12 V and 24 V appropriate very well (max 30 V). If symmetrical power supply, do not exceed + /-15V (absolute maximum of + /-18V). If you absolutely want to use a power higher value, then you should choose a double op amp that is able to handle this voltage. If you want to integrate this set into a AF amp and use existing power to the amp.
