Given: AT4040 has an open circuit sensitivity of -32dB/25.1mV in relation to 1 volt / 1 Pascal. Amplifying this signal, or raising it +32dB to 0dB produces a 1 volt output. Question: does this mean the amplifier must provide 32dB of gain to amplify the mic output to near line level? If so, then the mic sensivity specs are a good indication of the preamp gain requirements. Taking a worse-case example, the Beyer M201 dynamic full-range mic. It is rated at -58dB/1.2mV. Does this mean the preamp must have 60dB of gain to accomodate this mic?
