I'm not sure if this is the right area or not but i was wondering if anybody has built wired a partyline intercom system or no of a simple and fairly cheap one to buy?

Thanks,

Wow. Cool! :)

Once for a small 3-camera shoot I was asked to construct an intercom. I used an old Tascam M-06ST mixer that I had laying around. Combined with some $5 computer analog headset mics, unbalanced mic cables, headphone extension cables, and the most expensive items- plug-in-power-boxes for the mics, it worked perfectly for 4 people.
In fact we all agreed it had the best sound of any intercom we had ever used.
However, it was a "contraption". Not convenient or professional looking and the maximum distance it ran was 50-feet to the director in another room (2x25-foot cables each for both mic and headphone return).
If you were willing to have better combo cables made and used dynamic mics that didn't require power and you have an old mixer laying around it could be done and be very workable. But it would be up to you if that was a satisfactory solution versus a real intercom. It was a fun project and got the job done but it was the one and only use of the "JayCom 9000".

Jay,
What where the plug-in-power-boxes for the mics you where talking about?

Thanks,
Matt

I got them from SoundProfessionals online. They ran on 2 AAA batteries.
I can post the part number later.
