Well I plan to build a little box with $20 transformers, not the
expensive ones that Beachtek use (their box costs $293 here). It needs
to go from a line level to a mic level for the camcorder. Where do I get
information on how to pad the line level down to mic level? What is the
input impedance of the camcorder's mic level input?
Also if you put a cap in series with the audio line, doesn't it impact
the frequency response?
