yeah - you can do it, but you need an adapter. The earphone jack on a pad is a special jack with stereo headphone uot put and a seperate mic in channel. The adapters i have seen are usually built to accomodate a standard 1/4 in - into the pad, like the one in the attached link. In theory, you could use the lineout on the mac, to a 1/4 in male - then into this adapter to get it back into the pad. Some probably makes the cable you need with the 1/4 shift, but I couldn't find one.
Options - in you notes, insted of copying the file, put a link to the podcast
