azw Posted September 22, 2019 Report Share Posted September 22, 2019 Have an odd one.... Trying to power an Earthworks Periscope mic with a PSC pH48 supply and then go to a zaxcom Transmitter. Not working. What’s the output amperage of the PSC? Too low? Can’t find that out. The Periscope needs 10ma and 48v. Not a film job.... 😂 -Avi Quote Link to comment Share on other sites More sharing options...
azw Posted September 22, 2019 Author Report Share Posted September 22, 2019 Update - these might just be busted mics. I plugged them right into my Maxx and got the same result. Crackles and pops. Quote Link to comment Share on other sites More sharing options...
Ty Ford Posted September 23, 2019 Report Share Posted September 23, 2019 10ma is a lot, right? Quote Link to comment Share on other sites More sharing options...

Hi Ty, That would give you a 34 Volt drop on a DIN standard 48 Volt supply, i.e., 14 Volts at the mic pins. As I remember, the Earthworks mic is a high current draw mic with one leg being a current mirror of the other leg. We had to sell a pin flipping adapter for our HM series plug on transmitters.
