Good Day. So, let's stipulate I tried to match an inexpensive 60v condenser driver board with first, a 25 mm condenser capsule, and second, a 34mm condenser capsule ... and the results were vastly divergent. In the first case, volume, tonality, clarity, etc., were all within expectations. In the second case, output signal levels were substantially lower and while it sounded fairly natural, there was no verve, presence, excitement, articulation - in a word, dull.
Might this have something to do with a) size of capsule relative to b) 60 volts phantom voltage from the board, or c) none of the above - something else is going on? The smaller capsule seems to work with just about any condenser driver board. The larger capsule patterned after one or another famous design works well with some, but not other boards - for example it is a nice drop in replacement for a Behringer B-1 capsule, and it works well with the popular JLI OPA Alice board, but not all boards - say the original BM-500 type boards which produce varying results from good to disappointing. Why 60 v and not the usual 9-48 v requirement?
Any ideas? What makes these larger capsules so finicky or selective? Or ... is it ... ahem ... just me? JHR
