FBX-1020 CONTROLS
A/C Power Input
The FBX-1020 is factory configured to operate at either 115 VAC
or 230 VAC. Using the wrong input voltage may cause perma-
nent damage to the unit and will void the warranty.
Audio Inputs & Outputs
1/4" TRS and XLR balanced and unbalanced.
Active/Bypass Switch
Bypass mode takes the unit out of the signal path so that it will
have no effect on the program. In active mode, the unit controls
feedback automatically. The red BYPASS LED lights when the
unit is in bypass mode.
Signal Level
The LED ladder indicates the signal strength relative to the
FBX's input clip level. The red CLIP LED indicates clipping; it
also indicates the unit is in TURBO mode.
Reset
To reset ALL filters, hold the reset button for 4 seconds until all
filter LEDs are off.
Set Total Number of Filters
To set the total number of filters, depress the button for 4
seconds and then release. The LEDs will begin to light in
sequence. When the LED corresponding to the desired
number of filters lights, press the button to register your
selection.
Set Fixed
To set fixed filters, hold down the button for 4 seconds and then
release. The LEDs will begin to light in sequence. When the
LED corresponding to the desired number of fixed filters lights,
press the button to register your selection. (Factory default is
nine fixed and three dynamic filters.)
Lock Fixed Filters
When the LOCK FIXED button is pressed, its LED will light to
indicate that the FBX is in LOCK FIXED mode. LOCK FIXED
mode can be activated at any time after system setup and will
stay on until the button is pressed again and the LED turns off.
Engaging the LOCK FIXED button also takes the FBX-1020 out
of ClipGuard's TURBO setup mode.
Fifth Octave
Press the button at any time to select wider filters for any new
filters to be set. It is possible to have both 1/5 and 1/10 octave
Constant Q filters active in one channel simultaneously.
Filter Stage Activity
When one of the unit’s 10 filters is activated, the corresponding
LED lights. A blinking LED indicates the filter that was most
recently activated.
Power Switch
The ON/OFF switch is a two-position push button switch. The
power indicator LED will light when the FBX is operational.
