I was wondering about this for a while, couldn't find any info on how much LDC can produce (modulate pol.V. to be specific).
So i made this simple OPAlice circuit with opa1641 which is configured as buffer, and scoped output to see how large transient i can produce. For people not understanding what i'm talking about the output shows the same value as the input of the opamp - the output of the capsule, maybe tiny bit less. I polarized the capsule with 60v.
Here are the results, transient of a snare, and loud vocal scream in front of the capsule. One thing to note is that plosives of a vocal create easily peaks just as large as snare hit.
Notice that snare transient is asymmetrical due to the nature of the instrument, so a source capable of producing this kind of level with symmetrical waveform would give almost 12v peak to peak.
The opamp can take quite large input without distorting at all, so there is no clipping whatsoever. It can take much more than fet or a tube in plate out configuration.
