This sounds like useful progress.

For a quick test you should be able to feed the microphone into the IA10 (which is a balanced analogue input card if I recall correctly).

There are plenty of articles on the web to help guide you how to wire things up: you won't get an ideal impedance or gain match but you should be able to get something. In any case, it looks like the IA00 card would have been excessively loading your power supply and you may well get some noise now on starting room correction even though it won't proceed if the microphone signal is too weak.

Good luck.
