Just got that one, and using the example for AnalogSerialInput, but I only get 500+-, no reaction what so ever.

How come?

It doesn't look like the output of that board is rectified. Try using a diode, connect the anode to the audio output and the cathode to the arduino input.

Seeing as the OP Amp is powered from a single voltage rail  and is DC coupled there is no need for a rectifier.

However, are you sure that you are powering the electret insert correctly?
