how can i measure condenser capsule to match ?

[tuprimo]

Hello. I am going to buy several "unmached" primo272 capsules and I would like to know how to measure their sensitivity to match them.

What is the fastest and easiest way?

My idea is to place them at the same distance from a speaker and with REW measure their response.

First question, the capsules need "pip", how could I connect them to a sound card? I guess phantom power can destroy the capsules because there are too many volts...
I have an Olympus LS-10. Could I just connect the capsules to the recorder, and send the earphone output (ear) to the sound card? This would degrade the signal, but since it will be the same degradation for all the capsules, wouldn't it be a problem?

I don't want to know their exact measurements, just compare them to match them.

any other alternative? I suppose I could add a battery to power the microphones but I don't know how to connect it.

thank you so much.

Most 3.5mm headphone and headset inputs provide Plug-in Power, including your LS-10.

If you want to use an audio interface instead, then you need to buy an appropriate adapter:

These will convert 48V Phantom Power into Plug-in Power for your Electret capsule.
