OPA134: Line in stage op-amp

Part Number: OPA134

Need help calculate general purpose line in stage op-amp, Inverting op-amp, single Power Supply +12V

This stage should accept input audio signal from various audio line out.

Since line out output levels usually can vary between 0.3 and 1.2  VRMS, depending on impedance, there is no standard, that stage may have no overall gain, i.e. op-amp can work as unity gain buffer (voltage buffer), or can have minimal gain, limited to 2V on the output.
