Since the input is mono, the recording is normally performed 
as a mono recording onto one track. Press one of TRACK [1]–
[6] at REC TRACK to select the one track to which to record. 

However, if you want to record in stereo to increase the effect 
of insert effects, you can simultaneously press the [1] and [2], 
[3] and [4], or [5] and [6], REC TRACK buttons for stereo 
recording onto two tracks.

In addition, Tracks 7/8 are stereo tracks, so they always 
produce stereo recordings.
