Casio FX-602P

Great you got that working - nice hack with Audacity /afplay!

Interesting that the recording is coming out so low. Just to be clear, when you play it back it in Audacity, it's showing that it's about 20dB below peaking out (0 dB) on the level meter?

I couldn't find an English FA-2 manual, only German, but I was able to glean that the FA-2 output is at a very low, microphone level (3mV). Is is possible that the input on your recorder is expecting a line level (around 1000 mV)? The manual should tell you. If it's a microphone input is there's some way to adjust the input level / sensitivity? Sometimes there's a switch or software setting for the input gain.
