Performing Level Selection

The Double-Press
To reselect a level, first deselect the level, then select the level. That is, press the level button twice.
You can considered this action a “double-press.”

A double-press gives the level precedence over other selected levels.

In the example of Figure 13-7, If you double-pressed A12, the result would again be like Figure 13-
6.

Standard Mode Summary
Rule 1:
when all levels are selected, the sources and destinations that are enabled are those that
include the level that is controlled by the level button with the lowest button number.

Rule 2: when not all levels are selected, the sources and destinations that are enabled are those that
include the level that you select last.

‘Takes’ occur on all selected levels. Destinations (and sources) are enabled by the level with prece-
dence:

• (Rule 1) precedence given by the lowest level button number.
• (Rule 2) precedence given by the most recently pressed level button.

‘Takes’ can occur only for enabled destinations and sources.

Level Selection in Enhanced Mode

In enhanced mode, level buttons do not enable or disable levels, but select levels.What enables and
disables the levels is the destination: whatever levels the destination includes are enabled when you
press the destination button
to begin a take. These levels remain enabled during the take. Other lev-
els are disabled and remain disabled during the take.

Enhanced mode has two submodes: hold and no-hold. The submodes affect breakaway. In fact,
level selection applies only in breakaway:

• In no-hold mode, the selected levels persist only until you press a breakaway source. Then they

revert to the levels of the destination.

Not pressing a level button before pressing a source results in a normal take from that source. It
clears the breakaway condition during the take.

• In hold mode, the selected levels persist until you change the level selection or you press

another destination. (This allows the operator to try different sources.)

Clearing a breakaway condition during the take requires more effort in hold mode than in no-
hold mode.

Clearing a breakaway after a take (perhaps after many intervening ‘takes’ to other destinations) is
as simple as performing a normal take to a destination that has breakaway.

For normal ‘takes’ in enhanced mode, the levels selected are always exactly those included in the
destination’s level list.

In enhanced mode, all defined sources and destinations remain enabled without regard to level
selection. Button ordering (spatial or temporal) is not a factor in enhanced mode.
