phantom 48 V t o 2.5 V converter

I need to design a circuit to convert a 48 V phantom mic input in a 2.5 V to use it with a imic-w. ( see that in http://www.mic-w.com/products.php?cid=46)

It´s possible to do? in a easy and inexpensive way!

The questión is related to a experience with no professional equipment of audio in an architectural acoustic course.



Thanks in advance
