voltage out of a ps-2
« on: October 26, 2005, 06:01:13 PM »
i asked a question in another thread http://taperssection.com/index.php?topic=37690.30 but it may have gotten buried.  so i thought i would pose the question here and see if i could get an answer.

i tested the voltage for my ps-2 on the mic in side and got a nice 51.7vDC... what should i get on the mic out side?  also which pins should i test across and which one is the hot one (red) and which is the black...

thanks
chris

There shouldn't be any DC voltage going out on the other side of that phantom power supply. To measure the voltage on the microphone side, Pin 2 (positive) to Pin 1 (negative), should be around 48 v DC. Also, the voltage, Pin 3 (positive) to Pin 1 (negative) should also be around 48 v DC. There should be no voltage measured from Pin 2 to Pin 3. The PS-2 is a pretty good phantom power supply if used with microphones that don't have a high current need.
