The picture below shows these connections:
The audio path should be broken at the input to the audio amplifier just before the volume
control. The only requirement at this point is that a minimum of 10 millivolts RMS and a
maximum of 150 millivolts RMS will appear at this point when using the Low Power
version of the ADSP

. Normally, there is a capacitor at this point (0.1 uf is a typical
value) to couple the stages together. Remove this capacitor and connect the ADSP

board
in its place. The board has coupling capacitors on its input and output.
