How to correctly connect a microphone to Marantz PMD 430 CP 430 Uher 4200

This applies to transistor inputs of 10KΩ.


The moving could microphone of 200Ω impedance is stepped by a microphone input transformer.


The high resulting signal voltage of low noise is fed to a high impedance JFET or electron tube input.


The 10KΩ output impedance of the single ended class A (electrons flowing all the time) of the JFET or electron tube is a perfect match.


The signal input to the recorder is high and big (like that of a Neumann U47 microphone).


So there is no hiss on the analog recorder at reproduction.


And the sound quality is so good.


Every detail of the sound source like an electron microscope information extraction. The singer does not need to force at all.
