Anyone interested - perform this check: Connect the output of an amplifier to the Iyonix/Aria "Audio-in" socket. Switch or connect amplifier to any source (CD, radio or mic) and set the gain so that it is audible through the internal speaker. ************************************* Warning - be careful not to set the gain too high - as this may destroy the audio circuitry on the motherboard. I am sure that protection is built in but hey - lets not take chances! ************************************* The application - AudioIn can then record the source (source set to line in) and save it as a WAV file.
