Those are DIN connectors. DIN line-level signals expect a different impedance than is usual for RCA or XLR connections. IIRC you can put a resistor in series to convert to RCA.
I'm not sure what signal level and impedance DIN microphones use. I'll see what I can dig up.
It looks like this is a dictation microphone. One of the connectors allows you to ...

The sound reminds me of Roland synths. I have a vague memory of a friend with an old Juno that had a patch like this. I can sort of mimic it with my DX7. The key is that there should be some high pass filter opening as part of the attack envelop (if you are using subtractive synthesis).
For FM, if you start with a decent brass patch (has some internal ...
its a trumpet sound with some sort of damping/volume reduction, maybe even a compressor... easily achievable in any synthesizer that has a trumpet preset on it. It might even be sidechained to the pad or beat. Try these ideas out and get back to me if nothing works.
Well, derjur beat me to it as I was going to suggest doing it for real as well!
Cassette players are cheap on eBay, I got one last year for futzing things and it was about £9. Tapes are cheap too as no one wants them anymore!
You should be careful of your choice of microphones and recording medium here. Although it may be tempting to use all vintage equipment, you may run into problems later such as tape hiss, preamp noise, and general signal-to-noise issues that cannot be easily fixed with modern tools like CEDAR or WNS. A smarter approach would be to record your foley with ...
Very interesting project. I have seen these plans posted in other places. The weakness of this design is that you will actually need a separate microphone at the end of each tube, instead of a single mic at the end of the funnel. The tubes may resonate and amplify, but whatever gain they have is lost in the "collector"--i.e. the area inside the funnel where ...
