Power Cycle
Current mixing and audio processor settings — the current state of the device — are saved
in nonvolatile memory. When the unit is powered off, all settings are retained. When the
unit is powered back on, it recalls settings from the nonvolatile memory. If a configuration
was in process during the power down, these saved mix, audio level, and audio DSP
processor settings become active.
On power up, the power/reset LED (

) lights solid when the unit is available for operation
or configuration.
