Phantom Power Adapter
« on: May 18, 2009, 05:09:17 PM »
Can anyone tell me what the output of a phantom power adapter is....

I know they take anywhere between 11-52volts at input but what do they put out to the mic...

is it 9volts?

Peace ook...

It's the other way around... most a powered with a 9v battery (or several) and output the 48v to the mic.

OtheroneK,

I think they send 9V or so to the capsule. It can be less too. The 11-52V from the phantom power is reduced inside the adaptors.

Chuck in this forum used the AT8533 with his "Franken-Naks". They dropped the output by about 10dB. There is an balancing output transformer inside the AT8533 (just like the one inside the Nakamichi CM-100 and CM-300). Chuck got some adaptors from Naiant, that have an actively balanced output giving a hotter output.

All these adaptors should be close to the capsule as the cable between the capsule and the adaptor is unbalanced.
