sorry, i'm sure this has been answered before, but i'm still unclear on some issues...
i'm unclear on some of the terminology used ever since i built these ke4 capsule mics.
from naiant site
<In standard configuration, the PFA supplies +9V across 5.6KΩ resistors to each microphone channel.>
-does this have anything to do with input impedance or is it specific to the plug-in power circuit?
-do all battery boxes provide the same 5.6k load?
-on the ke4 datasheet it says that the capsule wants 5.6k at voltages between 2.5 and 5v, but at 9v it wants 18k,
so is the ke4 an exception?
-is the 5.6k resistor the same thing as a source resistor?
not sure what load the oscartech or 4060 mics want to see
so i'm gathering that there is no standard for plug-in power and loads. on average i'm guessing that 5.6k through 9v works well, but
this is possibly not optimal for every mic?
to optimize each of these mics then is it best to use a preamp designed specifically for them? or does the load not play too big a part in the sound. i know that for ribbon mics the loading makes a big difference in sound. when i emailed oscartech they recommended one particular mic based on the impedance of the pcm-m10, so i'm inclined to think that impedance does matter from mic to mic.
when people are running balanced high ouput outboard preamps, what is the best way to unbalance the signal to connect with consumer recorders without loss of quality? or is it best to mate balanced outboard pres with balanced recorders.
