6.5 How To Set Up The FBX Section Of Your True Mobility TM System
Follow these steps to obtain the maximum gain and protection from feedback.
1. Place the speakers in the positions where they will be used during the program.
2. If there is any equipment with a noise gate in the signal path, you MUST DISENGAGE the noise
gate(s) prior to the setup procedure. You may reengage these noise gates upon conclusion of your
FBX setup.
3. Patch your Sabine receiver into the mixer or amp channel. Set the amp master output gain to a
normal operating position.
NOTE: The level of your power amplifier should be set to a
level that allows a healthy gain structure prior to the ampli-
fier. If your amplifier is turned up fully, and your mixer meters
show little movement when signal passes through, you will
improve the performance of your sound system and lower
system noise by reducing the gain on your power amp and
increasing your mixer gain.
4. Turn on your wireless transmitter or
handheld microphone, then the wire-
less receiver, then the mixer, then any
other accessories, and finally the
power amp. If you are using a graphic
EQ, adjust only for the desired tonal
qualities, but DO NOT NOTCH FOR
FEEDBACK.

6.4.2 Default FBX filter settings
The Sabine True Mobility
TM
Wireless System provides a total of ten filters for feedback control. The
default setting makes seven of these Fixed and three Dynamic. This can be changed to eight Fixed and
two Dynamic by changing an internal DIP switch position (see Appendix 11.1 FBX Configuration DIP
Switch).
6.4.3 FBX filter width
A default setting of .10 octave has been calculated to eliminate feedback without affecting music
program. If, with all filters properly set, feedback is still occurs, the FBX filters may be set to .20-octave
width. This wider filter setting will help to eliminate feedback trouble areas, but may also affect music
program slightly. The wider setting is generally considered to be appropriate where speech is the primary
usage of the Sabine Wireless. This is to say it will not audibly affect desired program, only feedback.
If the Sabine Wireless is used for music program, we recommend using the default setting of .10 octave
be used. You can change FBX filter width by repositioning an internal DIP switch (see Appendix 11.1
FBX Configuration DIP Switch).
