Phantom Power via 1/4" TRS Balanced Patch Bay

[paulpatras]

I've searched on the DUC and elsewhere and have found several opposing opinions on this. Is anyone doing this or something similar?
Here is my situation...I have a project studio in my home which has a great sounding room about 40 feet away from my 001 setup. I'm thinking about using a 12 channel / 4 input snake cable (1/4" balanced TRS to Female XLR) from the room to my patch bay, to my preamp, into my 001.

I am hoping to use condensor mics in this room. First of all, will the 48V phantom power continue over that long of a distance? Will a 1/4" Balanced TRS Patch Bay accept and send the power?

If you have successfully done something similar, please let me know. If you have other suggestions, I would appreciate any input you may have.

Thanks a lot for your time and consideration.

Phantom power is capable of driving 1000's of feet of good wire with good quality connections (it is DC and does not suffer from the inductance issues of AC in wire).

You can run phantom power through a patchbay with no problem, but you have to be carefull about a couple of things:
If you are using normaled thru's make sure there is a ground connection between the to jacks that are normaled (other wise no phantom).

Be careful what you plug in. For the most part newer equipment can handle being plugged into phantom power because new gear tends to have very low impedence outputs. The phantom power is delivered via a 6.8k ohm resistor from you preamp or console, so if it is connected to a low impedence there will be very little voltage across the low impedence output (voltage divides proportional to the resistance).

I do it in my studio, but you do have to be careful.
