That's how most of us are using it, Ed. It's the entire reason for being of this recorder as far as I'm concerned.
Hello All,
All the reviews I've read, mention recording four tracks using the internal mics and line in, nowhere have I seen a mention of recording line in and external mic's, recording to four tracks. I am assuming from the comments here, that if a pair of mic's are plugged into the ext mic socket, and a pair of mic's via a preamp are plugged into the Line in socket, they can be recorded on two stereo track's.
If this is correct, I'm wondering why nobody has mentioned this in reviews, or is it something that is not documented, and has been discovered by a user.
