PRE-AMP Research

When i first realise i would need a preamp to get the microphone signal to line level for my interface (Behringer UCA202),  I initially thought i would use a LM358. However upon more research i found that although this would be adequate a more appropriate intergrated circuit would be the NE 5532, which is a high performance low noise operational amplifier.

Consideration to the potential of need two preamps with phantom power to support condenser microphones:
