8.11. Auto-Leveler Settings (only when the auto-leveler mode is selected in Section 8.9.)
The auto-leveler function performs to keep the output level constant by suppressing the change of sound
volume. Setting the target level (the constant level to be automatically adjusted to) and the maximum gain (the
amount of gain to bring the lower level to the target level) automatically compensates for the input level. Note
that setting an excessive amount of gain increases the input sensitivity, easily causing feedback.
Note: No following displays appear when the compressor mode is selected.
ON When any of the following screens is displayed, the auto-leveler function for the displayed channel
can be enabled or disabled with the function ON/OFF key. When enabled (ON), the function
ON/OFF Indicator lights.
