5. Now you are ready to set FBX filters. Press and hold Setup (far left button) on the wireless receiver,
until the LEDs flash four times, then release it (the Setup LED will come on). This will clear any
FBX filters already in place. You should do this each time you move your sound system,
change a sound system component, or relocate your microphone. Your Sabine True Mobility
TM
Wireless System will remember its settings from the last time you turned the unit off.
6. When the Setup light comes on, your receiver is ready to set FBX filters. With the microphone
turned on, raise the Output Level of the receiver slowly until a strong input signal at the mixer is
apparent (for starters, try the 12:00 position). The microphone should now be audible.
7. During Setup mode, do not talk into the microphone or pass audio program through a transmitter.
This may cause the Sabine True Mobility™ system to set inappropriate filters. The only appropri-
ate use of the setup mode is to create and filter feedback.
8. Slowly raise the mixer channel gain to the point of feedback—and then slowly beyond until you
hear the chirping tones of feedback quickly being eliminated by FBX filters setting. Stop raising gain
after 2 or 3 feedback tones have chirped and corresponding FBX filters have set. Rest assured that
any feedback that occurs will be at a quiet volume, and very short in duration.
9. Move the microphone to another area of use and slowly raise gain until FBX eliminates a few more
feedback tones (2 or 3). Repeat this step until the Setup indicator automatically goes off and the
Ready indicator comes on.
Any feedback that occurs after setup
will be eliminated by Dynamic filters. In
most instances you will experience an
additional gain of 6-9 dB before feed-
back when using the Sabine True
Mobility
TM
System. Precise results will
depend on system and acoustical con-
siderations.
All fixed filters in place will remain set until the Setup button is pushed and held as described in step
5. All dynamic filters will remain in place until new feedback occurs (wherein they will move to the new
frequency), or until the Setup button is pushed and held.
6.6 Bypass Button
The Bypass button bypasses only the FBX Section, and not the additional signal processing (de-
essing and compression) available in the Targeted Input Processing section of the Sabine True Mobility
TM
Wireless Receiver.

You may quit Setup mode at any time prior to its automatic exit by simply pressing the Ready
button. This will lock all fixed FBX filters, including those not set at the time of your manual
exit—in other words, only the filters set at the time you pushed Ready will be engaged. Dynamic
FBX filters will still work in the event of feedback during performance.
If you quit Setup prior to the FBX Section’s automatic exit (i.e.., after all fixed FBX filters are set),
and later decide you need more gain before feedback (i.e., more fixed filters), you must begin the
Setup process again. See Step 5 above.
