I'm getting more confused the more I read about this subject.
I bought a BDS condenser mic which takes a single aa battery.
When I use it, It definitely works better with the phantom power on but it has a 1/4 inch jack into the keyboard and not the three pin xlr connection.
Now, some sites say It must have the xlr jack for it to work and some sites make no mention of the jack end being important. Others say it might even damage the mic.
I know it's a cheapie but I bought it to see if the vocal side of the pa3x was worth pursuing. I can see it is. The mike is supplied with a high quality lead which I assume is shielded(balanced). A three pin connector goes into the back of the Mic.
