appropriate menu. Then press Enter. To descend a menu level (go deeper into the
tree), press Enter. To ascend a menu level (go back toward the top of the tree),
press ESC.
The Meter button will also access the Meter tree directly. The menu trees are
structured in levels, such that the first level (top of the tree) branches into multiple
subcategories (see Figure 2.7). These branches typically end when an adjustable
parameter or viewable value is reached.
Adjusting a value
To adjust a parameter, first verify that it is flashing. If the parameter is not flashing,
it cannot be adjusted until you press Enter. If the parameter is flashing, adjust the
value with the Up and Down buttons. As the value is adjusted, the parameter is
updated immediately. For example, if you adjust input gain, you should be able to
hear the difference as it changes. To store the new value, press Enter. To discard the
change and revert back to the old value, press ESC. In general, while adjusting
parameters, numerical values do not wrap around when the end is reached. However,
parameters that toggle between two values (or are a list of values) will wrap around.
When adjusting a parameter, press and hold the Up or Down button for more than
two seconds to scroll through the values at a faster rate.
