f. "Remember Fixed on Reboot" Speakers are sometimes used in the same setup for extended times.
During this time speakers may be powered on and off multiple times. Turning on "Remember Fixed on
Reboot" sets the fixed AFS filters to maintain their found frequency assignments on next speaker bootup.
In general, most users will leave this setting turned on, in case power is accidentally dropped in between
the soundcheck AFS Fixed filter setup and the event. Groups that move speakers to new locations often
may desire to set this feature off, as each location has different feedback challenges, which previous Fixed
filters would not assist.
5. The Master EQ is a package of filter adjustments on the main mix before the audio feeds to the amp and
speaker. It includes a collection of easy to select preset curves for common speech and music styles. Each
preset can also be loaded into the Custom preset for detailed user-adjustable of output parametric EQs. The user
has adjustments for individual band level, frequency, and width ("Q").
a. "Master EQ" On/Off enables or bypasses the current settings in the Master EQ processor.
b. "Reset" selection resets the Master EQ to flat, as the default Master EQ setting when shipped.
c. "Presets 8x" enables rotation of the Master/Menu knob to view and select from the Master EQ presets.

Turn off the "Live AFS" while operating the Learn Fixed setup.
When all fixed frequencies have been filled, the "Learn AFS" will automatically turn off and the Fixed
Filters are locked on for the event.
If the user is unable to get all the fixed AFS filters to complete frequency assignments, the user can
manually turn off "Learn AFS" by clicking the "Learn Fixed" setting again. Turning off "Learn AFS"
automatically leaves on the Fixed AFS On/Off setting.
After completion of the Learned Fixed setup, turn on "Live AFS" for additional feedback suppression
during a live event.
