The Pleiades studio

at the moment consists of the following signal path:


Mic - Uher 4200 report - JVC Nivico radio used as subtle bass boost compensating amplifier for using a small speaker - Pleiades linoleum Auratone type 5C speaker


First recording of a demo of It's the Summer Time sounds somewhat good on male voice (when not singing softly) and average of female voice.


This is good news as the case may be that this setup at once reveals a fault in the recording process. Voices sounded muddy.


But it is not a problem of the Uher, neither the JVC radio, nor the Pleiades Linoleum Auratone type 5C monitoring speaker as when recording or playing back a commercial recording from CD for example the sound is not only nice but impressive, full of detail including extended high frequency.


The mic used so far is an AKG MI 201-100, a plastic omni.


The reason of the bass heaviness should be the Fletcher, Munson equal loudness curves, voice effort curves.


So next time, a Pleiades (R,L) gentle slope low cut filter will be used in order to make the frequency response flat from producer's brain to listener's brain [Lowe, Morgan].
