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.
