On Compensating for Flat Frequency Responce from Singer's to Listener's Brain by Adjusting the Primary Inductance of the Microphone Input Transformer

In music industry as in any industry what matters is the perception of the consumer's brain.


For example when producer Bones Howe recorded Aquarious - 5th Dimension feedback or experience to his brain made him choose the V1 low cut setting on the RCA 77DX microphone [1]. The V1 switch connects an inductor (reactor) in parallel with the microphone output. Combined with the mic's output impedance it creates a low cut slope of 6dB per octave. the turnover defined by Zout and L.


The V1 turnover  setting was chosen because this sounded correct to his brain at the given playback intensity and ultimately to the consumer's brain.


It is known that flat frequency responce from microphone to loudspeaker does not in general produce a flat frequency responce from singer's vocal chords to listener's brain. [2]


Generalizing we may state that the ultimate goal of production and reproduction is flat frequency responce from artist's brain to listener's brain.
