I also use the H2.
I've been using it to record my gigs using my 3K.
The setting I've been using is MP3 320Kbps coming out of the headphones jack into the H3 and it sounds good.
I tried coming out of the Aux Output, but the level is fixed and it was total distortion in the H2.
Is there a better way to record like maybe as a Wav file?
