Recording with a Philips CCS 400 Conference Unit... How?

Tweakers' Asylum

Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ.

Hello all,
I recently got my hands on a Philips CCS 400 Conference unit, like the one they use in the UN for interpreters and such.
CCS 400
Microphone
Talk Button and DIN 8
Back Panel
The microphone probably isnt the best, but I would like to give this little project a try... that is I want to use the microphone on the unit as a recording microphone.
I have looked everywhere, I have even contacted Philips and a host of others in the lower hierarchy, as the section of Philips that made these, were sold to Bosch, if I am not mistaken. None of the contacted will provide schematics, they cant even tell me what the prongs on the DIN 8 connector are for.
So here I am, without a clue as to where to start.
This leads me to you.
I have now opened the unit, and I took some pictures.
I figure the most important elements of inquiery are:
- operating voltage(since it is probably a small condenser mic)
- prong identity - where can I get the signal from the mic
Wiring out of PCB
PCB Top
PCB Bottom(1.4MB)

If anyone has advice or knows something about this unit and its wiring, I would be very happy to hear from you!
And of course thank you for the attention.
