here's some interesting info from countryman...
<< i'll be using a sony pcm-m10 to record to. i read that they provide 3v with no load and slightly less with a load. if it is slightly less then it's ok for me to sacrifice a little headroom. if that doesn't work as planned then i have preamp that will supply 9v plug-in power, but i think i'll be ok with moderate volume levels just going straight into the m10 since other people have done it successfully.>>
The PCM-M10 provides 3V through 4.7kOhms to the mic, which is not enough power for the B3. I would highly recommend going with an EMW instead. So the following will be my suggestions for an EMW -- approximately the same cost as the B3 (maybe even slightly lower), and very similar performance specs.
<< i'd be wiring these into a single stereo mini mini plug, one mic left, one mic right. i thought that the wireless mics had two wires, maybe i'm mistaken.>>
They have three wires, but they are often used in three-wire mode. By tying black and shield to ground, you are effectively turning it into a two-wire mic.

<<some people are using a source resistor, either 2.2k or 4.7k depending on how loud their material is, to prevent overloading. i'm not sure if i need to do this, but that was one of my questions.>>>********
There is already a source resistor internally in the recorder, which is already providing barely enough power to operate our mics (and not enough for the B3), so I would strongly discourage the addition of an extra source resistor.
<<<<< XXXXX (named hidden) also goes a step further in measuring each individual mic's resistence and calculates a source resistor value accordingly. what do you think about this? is it necessary?>>>
This could be for other mics, or possibly other recorders. It is not necessary, and I would even recommend against it since you are already in a very low voltage / low current mode of operation.
<<< the people who have used these mics in the same manner that i intend, stereo connector into an m10, also report asymmetrical waveforms when not using a source resistor.>>>
Not sure what you mean by assymmetrical waveforms. The mics will not be a matched pair (we don't sell them that way) but will be close in their frequency response and gain.
<<<also, when ordering the microphones from a vendor, does countryman supply the connector and put it on, or would i have to solder the connector on myself.>>>
We can definitely wire the mics for you into the 1/8" plug. Please just call us first to get the part number and pricing, then you can order through your normal dealer or directly through us if you do not have a dealer. But I strongly recommend going with EMW or B6 mics rather than B3 mics for this application.

so the emw might be the better way to go. anyone have opinions on the sound vs the b3?
or i could just go b3 and only expect it to work in medium volumes.
does the emw use the same capsule as the oscarsoundtech mics?
i'll edit this post after replies because i probably got some technical things wrong...
