TURBO MODE
Turbo Mode is designed to allow maximum
feedback sensitivity for setting fixed filters
during setup only. This default setup mode
allows the FBX to grab feedback much
faster and at a much lower level, making
setup faster and quieter. When a channel
of the 2020Plus is in Turbo mode, the clip
level light flashes. DO NOT ENTER TURBO
MODE DURING A PERFORMANCE.
