Audio board for the Camera A2D project

Started working on the audio board prototype for the Camera A2D project. 
It's based around a pair of NE5532 op amps. The input stage converts the balanced line input from the microphone, and the second stage acts as a preamp with level control to supply the correct levels to the nNovia.
Should be on to some audio tests shortly so time to dig the signal generator and scope out.
