Figure 9.13.1: Menu mode view
Most PLM operating functions are accessed via the menu system in MENU mode. These include adjust-
ment of gain, selection of input type, limiter settings, network setup, etc. MENU mode may be accessed at
any time by pressing the
MENU
button on the front panel.
The menu system follows a conventional tree-and-branch structure: The ‘top page’ of the menu system (dis-
played when
MENU
is first pressed) gives access to various submenus, with the title of each in the seven
‘blocks’ of the display. Pressing the adjacent soft button selects that submenu, and the display changes to
a set of further options within the submenu. The top left block always indicates the current position in the
menu tree. These options may then be selected in a similar fashion, which in some cases may involve a
further ‘level’ of selection. When ‘parameter level’ is reached, individual PLM parameters may be selected
for adjustment by pressing the adjacent soft button. The displayed parameter value is highlighted (appears
in inverse video), and is adjustable by the rotary encoder. (The ring around the encoder knob illuminates to
confirm this.) Note that it may be possible to adjust two or more parameters on the same parameter level
page simultaneously simply by selecting all those to be adjusted. Any offsets in present values are retained.
Some of the PLM parameters assume multiple selection as the default setting, so all inputs or outputs are
normally adjusted simultaneously. Pressing
EXIT
at any time reverts the displays to the ‘next level up’, and
any altered parameters are retained automatically.
Note that soft button 1 does not have any options associated with it at any of the submenu levels. The text
in block 1 confirms Menu mode, and also the submenu and further options selected.
