Hi
Is this page of any help?

We have a Room 70 Dual G1 which comes (with a Codec Plus and 3.5mm input), in a large conference room. We used the 9m extension cable and then the mic cable itself so took us pretty far. I think the room is 13 mtrs, but with running it under the floor etc we still had ample length and it worked fine. Just make sure the join isn't yanked by someone where they pull the microphone itself which could disconnect the extension cable. We taped the extension cable and mic cable join securely to ensure the join stays firm.
Not sure about 100m length maybe someone else can confirm.

The max length that you will achieve will largely depend on how many cables and connectors you have in your path, the impedance of the cable and the voltage drop over that length of cable.  The more loss in the cable, the shorter distance you will be able to achieve.  Using quality cable and connectors can assist greatly in this.  It is possible to go very long distances (well over 100m) if you use the right products.
