Default Does anybody sell pre-made resistor "gizmos" for sm57/58 mics?

Surely all passive ribbon mics have output transformers, and the optimal

model or brand ?

Let me repeat: Microphone preamp input impedances should be 2K ohms or greater to *avoid* loading ribbon mics. "Optimal loading" would be NO loading whatsoever.


Let me repeat - FAKE NEWS !

Input impedance that a ribbon mic works into should be whatever is
specified optimal for the specific model of ribbon mic. They have either
a transformer (which should reflect the specified load optimally to the
ribbon), or an active preamp will will isolate the ribbon element
totally with a known and controlled load, and have its own specified load Z.

A passive ribbon mic with its inherent transformer may have markedly
different response into normal range versus very-high-to-none-at-all
loading.

But I could be wrong - Scott, Don ?
