If you bought the VXI Bias Box this does 3 things (I think) Supplies
3volts to electret mics (ie most VR mics). This is actually needed
rarely as most sound cards supply the 3 volts. It also matches impedence
of the mic to the sound card (also not usually needed). It also is a
booster (preamp). The preamp function is the one most often needed.
You might get the same effect by just manually setting the Windows Mic
Volume control higher than the audio setup wizard sets it.
