And, while the status-bar indicator 27) is on, channel
indicators (28) and LVL (29) will not be displayed. Also, if
adjustments are done in a mode where a certain channel is
not available, the adjustment step for that channel is

level cannot be adjusted since Phantom does not have a
center channel. In stereo, neither the center nor the
surround levels can be adjusted since Stereo does not
feature surround speakers or a center speaker. A seventh
press of the Level button will exit the ESC333 from its
