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