Neutric 3382 phantom power

[jallday]

Hello everyone. I hope that this is the correct forum for this question.

I have a elderly but excellent condition Neutric 3382 measurement microphone that I would like to use for speaker testing.

However, I do not have the original phantom power supply. I believe that the specs called for 15-30V, but I can only seem to get 48V supplies these days. I have found one internet comment from someone who seems to have run the mic. from such a supply to no ill effect, so I wonder if anyone can confirm that it should work OK?

Many thanks

Jonathan

48V is a standard, but I'm not sure about older mics.

Search for a manual of the Neutrik Audiograph 3300. That will probably make things clear. My memory fails me here, I thought it had 48V...

Or give NTI a call, they are the company these days that inherited the legacy of the Neutrik measurement equipment.

Wait. It’s 15V on the Audiograph. So build a voltage source fed by the 48V phantom power (some resistors and a zener maybe?) into a XLR connector and use that on a regular preamp.
