The microphone is 7' far from the source. The source produces pressure of 100dbSPL at 4'. So until 7' there will be a reduction of

20log(7/4) = 20log1.75 = 4.86dB

So the sound pressure level at mic will be

100 – 4.86 = 95.14dB SPL.

We know that 94db SPL corresponds to 1Pa of pressure, and on this mic 1Pa yields -46dbV. The sound pressure level at mic is 95.14dB SPL, which is

95.14 – 94 = 1.14dB SPL   

more. This means that there will be 1.14dBV more on the mics output also.

-46 + 1.14 = -44.86dBV

Between the mic and mic preamp there is a 10dB loss on mic pad, so the input to the preamp will be

-44.86 – 10 = -54.86dBV...
