Enhancements related to operation
If you rotate the MONITOR knob without pressing [SELECT],
you will adjust the volume level. If you are attempting to adjust
pan and inadvertently rotate the MONITOR knob toward the right
without pressing [SELECT], high-volume sound capable of
damaging your amp or speakers could be output.
When you release [SELECT] after adjusting the pan, the edit
screen of that channel may appear, but the MONITOR knob
will adjust the pan only for the channel whose [SELECT]
button is being pressed. For example even when the edit
screen for track 1 is displayed, rotating the MONITOR knob
while holding down the track 2 [SELECT] button will adjust
the track 2 pan.
The faders of two or more channels (inputs/tracks) can now
be assigned to groups, so that when the fader of any channel
is operated, the fader levels (volume levels) of all channels in
that group will be adjusted as well.
When fader group settings have been made, you can adjust
the overall volume of a group while preserving the volume
balance of the channels included in that group.

group will adjust all faders of that group.
If you select "Off," the fader will not be assigned to any
group (normal operation).
