PC Mic, I/O question.

[sonaiko]

I want to connect the PC's mic into the door intercom so i can talk with visitors while im setting on my pc. The mic inputs voice signal into PC. Whats next to do? Shall i use that option in windows that makes anything said on the mic to be output on the speakers? In this case all i have to do is connect the speaker output into the intercom's mic???

Was I clear enough?

Plz suggest.

Hmm, I would have thought it easier to connect the PC mic directly to the intercom, and just buy another to use with the PC, they are dirt cheap usually. Alternatively, you could just hack the intercom, and extend the wires going to the electret capsule using shielded cable. This may be helpful for you:

It is more than likely the mic in the intercom is an electret, so a suitable power supply will be available from that already.
