If you know balanced and unbalanced connections , this is for you!

[Joao]

I found two old capacitors philips microphones that were hidden in junk and I thought I'd take advantage of them. but I noticed that the microphones had an unbalanced cable! in the image below I will expose my problem

Try it. Let us know.

What's the question?

I wouldn't worry about balanced/unbalanced as long as the cable is shielded and not going very far.

The bigger question is "What impedance do they expect for a load?"

You connect the positive to pin 2 on the xlr, and connect the shield to pin 1 & 3. However it will probably be a high impedance mic (Hz) so the levels may be a bit off.

They used to come with the 4 track stereo recorders Phillips sold in the 70s - They worked well enough, but they're not exactly exciting by today's standards - and being a permanently charged diaphragm mic, they could well have suffered a bit and might be a bit dull.

I think is around 800ohms the impedance!

thank you guys

I take it the labels are misleading and it's only stereo because you have a pair?

There'd be some head scratching going on if you only had one of them.

Since it's an electret mic and uses a battery, its internal preamp will be powered by the battery, hence no phantom power.

If it's 800 Ohms, it'll do fine in most mic inputs. Just follow witzendoz's advice and change it to an XLR connector.

they are two mic, indeed xd the other microphone have the internal wires melted due to old batteries. i need to fix it. I am gonna use this mic just for lo-fi voices, blues harmonicas etc.

I would expect them to overload and sound very nasty on close up harmonica, especially as has been mentioned, some of the electret charge will have been lost.

N.B. Modern "back electret" mics can be very good indeed and some top names make them such as Rode.
