Remote right button configuration menu

[chrisc]

The right button, when pressed, cycles through the tone controls, then you end up with a menu with which you can toggle on/off with the volume control, ie:

MUTE          OFF/ON
PHASE         +
SUBSONIC    ON/OFF
ICM             OFF/ON
DPM            OFF/ON
PREOUT       OFF/ON

The booklet offers no explanation.  While it is obvious what MUTE, PHASE, PREOUT are for, what function or alteration to the sound do the other headings make?

Perhaps it has been explained on the forum, but I did not really know what to look for

Thank you
