Sennheiser KE4 capsule wiring

Hi everyone!

I'm a PhD in acoustics, particularlly in the subjective perception of room acoustics. So I know quite a bit about psychoacoustics, room acoustics and digital signal processing but I'm a complete noob about electroacoustics...

Anyway... For a binaural system that I have to assemble for my experiments I've got some Sennheiser KE-4 capsules http://www.music.mcgill.ca/caml/lib/exe/fetch.php?media=equipment:ke_4_211_2_gb.pdf that I have to wire.

In the datasheet you can see the recommended wiring for plug-in power but I really need to wire each of the mikes to be connected to XLR (with Phantom). I don't know how should I proceed to run this mikes with XLR and Phantom.

Could anyone enlighten me? I'm not looking for a very fancy circuit, just a circuit that allows me to capture up to 100dB without clipping.

Kind regards and thank you.

The Naiant PFA should work fine with these. 3-wire 9 volt configuration would be best. You would simply wire it as follows:

pin 1: shield
pin 2: source
pin 3: drain (9 volts)

You would still use the 18 K Ohm source resistor shown in the drawing. You don't need the coupling capacitor shown.

Yes, I have one of those, but since it's formy thesis, I don't have any budget for that and I have like 10 pairs of mikes to wire, I'd prefer to keep it cheap. I was thinking about some circuit to put inside the XLR connector.

Anyway, thank you for the answer!

I have experience with this microphone.
You can power with "plug in power" from most portable recorders.I put a 2.2KR resistor between source and ground.I power with Sony PCM-M10, Edirol R09, etc. plug in power.
You are welcome to contact me by PM for my email.

This items is out of stock to-day but it was not some weeks ago.

FWIW.
