LINE IN/OUT: LINE IN is a special connection that is compatible with any LINE OUT (or headphone jack),commonly found on portable CD players,
AM/FM/shortwave receivers,computer audio output, etc. LINE LEVEL Refers to a low level audio that does not change when you increase the Volume of the receiver or other audio device. You can connect the LINE OUT of any device through the supplied audio cables into the VersaCorder's LINE IN and record the audio from that device. The headphone jack of a radio or other device can be used if there is not a LINE OUT available. Since the headphone jack will vary with the volume control, it is best to do a test recording and play back to obtain best results.
MIC IN:
Just about any microphone will work well with the Versacorder. The jack is a 1/8" (3.5mm). VersaCorder Page 19
